Respondent Rock Against Racism (RAR), furnishing its own sound equipment and technicians, has sponsored yearly programs of rock music at the Naumberg Acoustic Bandshell in New York City's Central Park. The city received numerous complaints about excessive noise at RAR's concerts from users of the nearby Sheep Meadow, an area designated by the city for passive recreation, from other users of the park, and from residents of areas adjacent to the park. Moreover, when the city shut off the power after RAR ignored repeated requests to lower the volume at one of its concerts, the audience became abusive and disruptive. The city also experienced problems at bandshell events put on by other sponsors, who, due to their use of inadequate sound equipment or sound technicians unskilled at mixing sound for the bandshell area, were unable to provide sufficient amplification levels, resulting in disappointed or unruly audiences. Rejecting various other solutions to the excessive noise and inadequate amplification problems, the city adopted a Use Guideline for the bandshell which specified that the city would furnish high quality sound equipment and retain an independent, experienced sound technician for all performances. After the city implemented this guideline, RAR amended a pre-existing District Court complaint against the city to seek damages and a declaratory judgment striking down the guideline as facially invalid under the First Amendment. The court upheld the guideline, finding, inter alia, that performers who had used the city's sound system and technician had been uniformly pleased; that, although the city's technician ultimately controlled both sound volume and mix, the city's practice was to give the sponsor autonomy as to mix and to confer with him before turning the volume down; and that the city's amplification system was sufficient for RAR's needs. Applying this Court's three-part test for judging the constitutionality of governmental regulation of the time, place, and manner of protected speech, the court found the guideline valid. The Court of Appeals reversed on the ground that such regulations' method and extent must be the least intrusive upon the freedom of expression as is reasonably necessary to achieve the regulations purpose, finding that there were various less restrictive means by which the city could control excessive volume without also intruding on RAR's ability to control sound mix.
Held: The city's sound-amplification guideline is valid under the First Amendment as a reasonable regulation of the place and manner of protected speech.
(a) The guideline is content neutral, since it is justified without reference to the content of the regulated speech. The city's principal justification -- the desire to control noise in order to retain the sedate character of the Sheep Meadow and other areas of the park and to avoid intrusion into residential areas -- has nothing to do with content. The city's other justification, its interest in ensuring sound quality, does not render the guideline content based as an attempt to impose subjective standards of acceptable sound mix on performers, since the city has expressly disavowed any such intent and requires its technician to defer to the sponsor's wishes as to mix. On the record below, the city's sound quality concern extends only to the clearly content-neutral goals of ensuring adequate amplification and avoiding volume problems associated with inadequate mix. There is no merit to RAR's argument that the guideline is nonetheless invalid on its face because it places unbridled discretion in the hands of city enforcement officials. Even granting the doubtful proposition that this claim falls within the narrow class of permissible facial challenges to allegedly unconstrained grants of regulatory authority, the claim nevertheless fails, since the guideline's own terms in effect forbid officials purposely to select an inadequate system or to vary sound quality or volume based on the performer's message. Moreover, the city has applied a narrowing construction to the guideline by requiring officials to defer to sponsors on sound quality and confer with them as to volume problems, and by mandating that amplification be sufficient for the sound to reach all concert ground listeners.
(b) The guideline is narrowly tailored to serve significant governmental interests. That the city has a substantial interest in protecting citizens from unwelcome and excessive noise, even in a traditional public forum such as the park, cannot be doubted. Moreover, it has a substantial interest in ensuring the sufficiency of sound amplification at bandshell events in order to allow citizens to enjoy the benefits of the park, in light of the evidence that inadequate amplification had resulted in the inability of some audiences to hear performances. The Court of Appeals erred in requiring the city to prove that the guideline was the least intrusive means of furthering these legitimate interests, since a "less-restrictive-alternative analysis" has never been -- and is here, again, specifically rejected as -- a part of the inquiry into the validity of a time, place, or manner regulation. See Clark v. Community for Creative Non-Violence , 468 U.S. 288, 293; Regan v. Time, Inc. , 468 U.S. 641. The requirement of narrow tailoring is satisfied so long as the regulation promotes a substantial governmental interest that would be achieved less effectively absent the regulation, and the means chosen are not substantially broader than necessary to achieve that interest. If these standards are met, courts should defer to the government's reasonable determination. Here, the city's substantial interest in limiting sound volume is served in a direct and effective way by the requirement that its technician control the mixing board. Absent this requirement, the city's interest would have been served less well, as is evidenced by the excessive noise complaints generated by RAR's past concerts. The city also could reasonably have determined that, overall, its interest in ensuring that sound amplification was sufficient to reach all concert ground listeners would be served less effectively without the guideline than with it, since, by providing competent technicians and adequate equipment, the city eliminated inadequate amplification problems that plagued some performers in the past. Furthermore, in the absence of evidence that the guideline had a substantial deleterious effect on the ability of performers to achieve the quality of sound they desired, there is no merit to RAR's contention that the guideline is substantially broader than necessary to achieve the city's legitimate ends.
(c) The guideline leaves open ample alternative channels of communication, since it does not attempt to ban any particular manner or type of expression at a given place and time. Rather, it continues to permit expressive activity in the bandshell and has no effect on the quantity or content of that expression beyond regulating the extent of amplification. That the city's volume limitations may reduce to some degree the potential audience for RAR's speech is of no consequence, since there has been no showing that the remaining avenues of communication are inadequate.
The city's regulation requires bandshell performers to use sound-amplification equipment and a sound technician provided by the city. The challenge to this volume control technique comes from the sponsor of a rock concert. The trial court sustained the noise control measures, but the Court of Appeals for the Second Circuit reversed. We granted certiorari to resolve the important First Amendment issues presented by the case.
Rock Against Racism, respondent in this case, is an unincorporated association which, in its own words, is "dedicated to the espousal and promotion of antiracist views." App. to Pet. for Cert. 3. Each year from 1979 through 1986, RAR has sponsored a program of speeches and rock music at the bandshell. RAR has furnished the sound equipment and sound technician used by the various performing groups at these annual events.
Over the years, the city received numerous complaints about excessive sound amplification at respondent's concerts from park users and residents of areas adjacent to the park. On some occasions RAR was less than cooperative when city officials asked that the volume be reduced; at one concert, police felt compelled to cut off the power to the sound system, an action that caused the audience to become unruly and hostile. App. 127-131, 140-141, 212-214, 345-347.
Before the 1984 concert, city officials met with RAR representatives to discuss the problem of excessive noise. It was decided that the city would monitor sound levels at the edge of the concert ground, and would revoke respondent's event permit if specific volume limits were exceeded. Sound levels at the concert did exceed acceptable levels for sustained periods of time, despite repeated warnings and requests that the volume be lowered. Two citations for excessive volume were issued to respondent during the concert. When the power was eventually shut off, the audience became abusive and disruptive.
The following year, when respondent sought permission to hold its upcoming concert at the bandshell, the city declined to grant an event permit, citing its problems with noise and crowd control at RAR's previous concerts. The city suggested some other city-owned facilities as alternative sites for the concert. RAR declined the invitation and filed suit in United States District Court against the city, its mayor, and various police and parks department officials, seeking an injunction directing issuance of an event permit. After respondent agreed to abide by all applicable regulations, the parties reached agreement and a permit was issued.
The city then undertook to develop comprehensive New York City Parks Department Use Guidelines for the Naumberg Bandshell. A principal problem to be addressed by the guidelines was controlling the volume of amplified sound at bandshell events. A major concern was that at some bandshell performances the event sponsors had been unable to "provide the amplification levels required and 'crowds unhappy with the sound became disappointed or unruly.'" Brief for Petitioners 9. The city found that this problem had several causes, including inadequate sound equipment, sound technicians who were either unskilled at mixing sound outdoors or unfamiliar with the acoustics of the bandshell and its surroundings, and the like. Because some performers compensated for poor sound mix by raising volume, these factors tended to exacerbate the problem of excess noise.1 App. 30, 189, 218-219.
The city considered various solutions to the sound-amplification problem. The idea of a fixed decibel limit for all performers using the bandshell was rejected because the impact on listeners of a single decibel level is not constant, but varies in response to changes in air temperature, foliage, audience size, and like factors. Id., at 31, 220, 285-286. The city also rejected the possibility of employing a sound technician to operate the equipment provided by the various sponsors of bandshell events, because the city's technician might have had difficulty satisfying the needs of sponsors while operating unfamiliar, and perhaps inadequate, sound equipment. Id., at 220. Instead, the city concluded that the most effective way to achieve adequate but not excessive sound amplification would be for the city to furnish high quality sound equipment and retain an independent, experienced sound technician for all performances at the bandshell. After an extensive search the city hired a private sound company capable of meeting the needs of all the varied users of the bandshell.
The Use Guidelines were promulgated on March 21, 1986.2 After learning that it would be expected to comply with the guidelines at its upcoming annual concert in May 1986, respondent returned to the District Court and filed a motion for an injunction against the enforcement of certain aspects of the guidelines. The District Court preliminarily enjoined enforcement of the sound-amplification rule on May 1, 1986. See 636 F. Supp. 178 (SDNY 1986). Under the protection of the injunction, and alone among users of the bandshell in the 1986 season, RAR was permitted to use its own sound equipment and technician, just as it had done in prior years. RAR's 1986 concert again generated complaints about excessive noise from park users and nearby residents. App. 127, 138.
After the concert, respondent amended its complaint to seek damages and a declaratory judgment striking down the guidelines as facially invalid. After hearing five days of testimony about various aspects of the guidelines, the District Court issued its decision upholding the sound-amplification guideline.3 The court found that the city had been "motivated by a desire to obtain top-flight sound equipment and experienced operators" in selecting an independent contractor to provide the equipment and technician for bandshell events, and that the performers who did use the city's sound system in the 1986 season, in performances "which ran the full cultural gamut from grand opera to salsa to reggae," were uniformly pleased with the quality of the sound provided. 658 F. Supp. 1346, 1352 (SDNY 1987).
Although the city's sound technician controlled both sound volume and sound mix by virtue of his position at the mixing board, the court found that "[t]he City's practice for events at the Bandshell is to give the sponsor autonomy with respect to the sound mix: balancing treble with bass, highlighting a particular instrument or voice, and the like," and that the city's sound technician "does all he can to accommodate the sponsor's desires in those regards." Ibid. Even with respect to volume control, the city's practice was to confer with the sponsor before making any decision to turn the volume down. Ibid. In some instances, as with a New York Grand Opera performance, the sound technician accommodated the performers' unique needs by integrating special microphones with the city's equipment. The court specifically found that "[t]he City's implementation of the Bandshell guidelines provides for a sound amplification system capable of meeting RAR's technical needs and leaves control of the sound 'mix' in the hands of RAR." Id., at 1353. Applying this Court's three-part test for judging the constitutionality of government regulation of the time, place, or manner of protected speech, the court found the city's regulation valid.
The Court of Appeals reversed. 848 F.2d 367 (CA2 1988). After recognizing that "[c]ontent neutral time, place, and manner regulations are permissible so long as they are narrowly tailored to serve a substantial government interest and do not unreasonably limit alternative avenues of expression," the court added the proviso that "the method and extent of such regulation must be reasonable, that is, it must be the least intrusive upon the freedom of expression as is reasonably necessary to achieve a legitimate purpose of the regulation." Id., at 370 (citing United States v. O'Brien , 391 U.S. 367, 377 (1968)). Applying this test, the court determined that the city's guideline was valid only to the extent necessary to achieve the city's legitimate interest in controlling excessive volume, but found there were various alternative means of controlling volume without also intruding on respondent's ability to control the sound mix. For example, the city could have directed respondent's sound technician to keep the volume below specified levels. Alternatively, a volume-limiting device could have been installed; and as a "last resort," the court suggested, "the plug can be pulled on the sound to enforce the volume limit." 848 F.2d, at 372, n. 6. In view of the potential availability of these seemingly less restrictive alternatives, the Court of Appeals concluded that the sound-amplification guideline was invalid because the city had failed to prove that its regulation "was the least intrusive means of regulating the volume." Id., at 371.
We granted certiorari, 488 U.S. 816 (1988), to clarify the legal standard applicable to governmental regulation of the time, place, or manner of protected speech. Because the Court of Appeals erred in requiring the city to prove that its regulation was the least intrusive means of furthering its legitimate governmental interests, and because the ordinance is valid on its face, we now reverse.
Music is one of the oldest forms of human expression. From Plato's discourse in the Republic to the totalitarian state in our own times, rulers have known its capacity to appeal to the intellect and to the emotions, and have censored musical compositions to serve the needs of the state. See 2 Dialogues of Plato, Republic, bk. 3, pp. 231, 245-248 (B. Jowett transl., 4th ed. 1953) ("Our poets must sing in another and a nobler strain"); Musical Freedom and Why Dictators Fear It, N. Y. Times, Aug. 23, 1981, section 2, p. 1, col. 5; Soviet Schizophrenia toward Stravinsky, N. Y. Times, June 26, 1982, section 1, p. 25, col. 2; Symphonic Voice from China Is Heard Again, N. Y. Times, Oct. 11, 1987, section 2, p. 27, col. 1. The Constitution prohibits any like attempts in our own legal order. Music, as a form of expression and communication, is protected under the First Amendment. In the case before us the performances apparently consisted of remarks by speakers, as well as rock music, but the case has been presented as one in which the constitutional challenge is to the city's regulation of the musical aspects of the concert; and, based on the principle we have stated, the city's guideline must meet the demands of the First Amendment. The parties do not appear to dispute that proposition.
We need not here discuss whether a municipality which owns a bandstand or stage facility may exercise, in some circumstances, a proprietary right to select performances and control their quality. See Southeastern Promotions, Ltd. v. Conrad , 420 U.S. 546, 570-574 (1975) (Rehnquist, J., Dissenting). Though it did demonstrate its own interest in the effort to insure high quality performances by providing the equipment in question, the city justifies its guideline as a regulatory measure to limit and control noise. Here the bandshell was open, apparently, to all performers; and we decide the case as one in which the bandshell is a public forum for performances in which the government's right to regulate expression is subject to the protections of the First Amendment. United States v. Grace , 461 U.S. 171, 177 (1983); see Frisby v. Schultz , 487 U.S. 474, 481 (1988); Perry Education Assn. v. Perry Local Educators' Assn. , 460 U.S. 37, 45 (1983). Our cases make clear, however, that even in a public forum the government may impose reasonable restrictions on the time, place, or manner of protected speech, provided the restrictions "are justified without reference to the content of the regulated speech, that they are narrowly tailored to serve a significant governmental interest, and that they leave open ample alternative channels for communication of the information." Clark v. Community for Creative Non-Violence , 468 U.S. 288, 293 (1984); see Heffron v. International Society for Krishna Consciousness, Inc. , 452 U.S. 640, 648 (1981) (quoting Virginia Pharmacy Bd. v. Virginia Citizens Consumer Council, Inc. , 425 U.S. 748, 771 (1976)). We consider these requirements in turn.
The principal inquiry in determining content neutrality, in speech cases generally and in time, place, or manner cases in particular, is whether the government has adopted a regulation of speech because of disagreement with the message it conveys. Community for Creative Non-Violence , supra, at 295. The government's purpose is the controlling consideration. A regulation that serves purposes unrelated to the content of expression is deemed neutral, even if it has an incidental effect on some speakers or messages but not others. See Renton v. Playtime Theatres, Inc. , 475 U.S. 41, 47-48 (1986). Government regulation of expressive activity is content neutral so long as it is " justified without reference to the content of the regulated speech." Community for Creative Non-Violence , supra, at 293 (emphasis added); Heffron , supra, at 648 (quoting Virginia Pharmacy Bd. , supra, at 771); see Boos v. Barry , 485 U.S. 312, 320-321 (1988) (opinion of O'Connor, J.).
The principal justification for the sound-amplification guideline is the city's desire to control noise levels at bandshell events, in order to retain the character of the Sheep Meadow and its more sedate activities, and to avoid undue intrusion into residential areas and other areas of the park. This justification for the guideline "ha[s] nothing to do with content," Boos v. Barry , supra, at 320, and it satisfies the requirement that time, place, or manner regulations be content neutral.
The only other justification offered below was the city's interest in "ensur[ing] the quality of sound at Bandshell events." 658 F. Supp., at 1352; see 848 F.2d, at 370, n. 3. Respondent urges that this justification is not content neutral because it is based upon the quality, and thus the content, of the speech being regulated. In respondent's view, the city is seeking to assert artistic control over performers at the bandshell by enforcing a bureaucratically determined, valueladen conception of good sound. That all performers who have used the city's sound equipment have been completely satisfied is of no moment, respondent argues, because "[t]he First Amendment does not permit and cannot tolerate state control of artistic expression merely because the State claims that [its] efforts will lead to 'top-quality' results." Brief for Respondent 19.
While respondent's arguments that the government may not interfere with artistic judgment may have much force in other contexts, they are inapplicable to the facts of this case. The city has disclaimed in express terms any interest in imposing its own view of appropriate sound mix on performers. To the contrary, as the District Court found, the city requires its sound technician to defer to the wishes of event sponsors concerning sound mix. 658 F. Supp., at 1352-1353. On this record, the city's concern with sound quality extends only to the clearly content-neutral goals of ensuring adequate sound amplification and avoiding the volume problems associated with inadequate sound mix.4 Any governmental attempt to serve purely esthetic goals by imposing subjective standards of acceptable sound mix on performers would raise serious First Amendment concerns, but this case provides us with no opportunity to address those questions. As related above, the District Court found that the city's equipment and its sound technician could meet all of the standards requested by the performers, including RAR.
Respondent argues further that the guideline, even if not content based in explicit terms, is nonetheless invalid on its face because it places unbridled discretion in the hands of city officials charged with enforcing it. See Lakewood v. Plain Dealer Publishing Co. , 486 U.S. 750, 769-772 (1988) (4-to-3 decision); Heffron v. International Society for Krishna Consciousness, Inc. , supra, at 649; Freedman v. Maryland , 380 U.S. 51, 56 (1965); Thornhill v. Alabama , 310 U.S. 88, 97 (1940). According to respondent, there is nothing in the language of the guideline to prevent city officials from selecting wholly inadequate sound equipment or technicians, or even from varying the volume and quality of sound based on the message being conveyed by the performers.
As a threshold matter, it is far from clear that respondent should be permitted to bring a facial challenge to this aspect of the regulation. Our cases permitting facial challenges to regulations that allegedly grant officials unconstrained authority to regulate speech have generally involved licensing schemes that "ves[t] unbridled discretion in a government official over whether to permit or deny expressive activity." Plain Dealer , supra, at 755. The grant of discretion that respondent seeks to challenge here is of an entirely different, and lesser, order of magnitude, because respondent does not suggest that city officials enjoy unfettered discretion to deny bandshell permits altogether. Rather, respondent contends only that the city, by exercising what is concededly its right to regulate amplified sound, could choose to provide inadequate sound for performers based on the content of their speech. Since respondent does not claim that city officials enjoy unguided discretion to deny the right to speak altogether, it is open to question whether respondent's claim falls within the narrow class of permissible facial challenges to allegedly unconstrained grants of regulatory authority. Cf. 486 U.S., at 787 (White, J., Dissenting) (arguing that facial challenges of this type are permissible only where "the local law at issue require[s] licenses -- not for a narrow category of expressive conduct that could be prohibited -- but for a sweeping range of First Amendment protected activity").
Even if the language of the guideline were not sufficient on its face to withstand challenge, our ultimate Conclusion would be the same, for the city has interpreted the guideline in such a manner as to provide additional guidance to the officials charged with its enforcement. The District Court expressly found that the city's policy is to defer to the sponsor's desires concerning sound quality. 658 F. Supp., at 1352. With respect to sound volume, the city retains ultimate control, but city officials "mak[e] it a practice to confer with the sponsor if any questions of excessive sound arise, before taking any corrective action." Ibid. The city's goal of ensuring that "the sound amplification [is] sufficient to reach all listeners within the defined concertground," ibid., serves to limit further the discretion of the officials on the scene. Administrative interpretation and implementation of a regulation are, of course, highly relevant to our analysis, for "[i]n evaluating a facial challenge to a state law, a federal court must . . . consider any limiting construction that a state court or enforcement agency has proffered." Hoffman Estates v. The Flipside, Hoffman Estates, Inc. , 455 U.S. 489, 494, n. 5 (1982); see Plain Dealer , 486 U.S., at 769-770, and n. 11; United States v. Grace , 461 U.S., at 181, n. 10; Grayned v. City of Rockford , supra, at 110; Poulos v. New Hampshire , 345 U.S. 395 (1953). Any inadequacy on the face of the guideline would have been more than remedied by the city's narrowing construction.
The city's regulation is also "narrowly tailored to serve a significant governmental interest." Community for Creative Non-Violence , 468 U.S., at 293. Despite respondent's protestations to the contrary, it can no longer be doubted that government "ha[s] a substantial interest in protecting its citizens from unwelcome noise." City Council of Los Angeles v. Taxpayers for Vincent , 466 U.S. 789, 806 (1984) (citing Kovacs v. Cooper , supra); see Grayned , supra, at 116. This interest is perhaps at its greatest when government seeks to protect "'the well-being, tranquility, and privacy of the home,'" Frisby v. Schultz , 487 U.S., at 484 (quoting Carey v. Brown , 447 U.S. 455, 471 (1980)), but it is by no means limited to that context, for the government may act to protect even such traditional public forums as city streets and parks from excessive noise. Kovacs v. Cooper , 336 U.S., at 86-87 (opinion of Reed, J.); id., at 96-97 (Frankfurter, J., Concurring); id., at 97 (Jackson, J., Concurring); see Community for Creative Non-Violence , supra, at 296 (recognizing the government's "substantial interest in maintaining the parks . . . in an attractive and intact condition, readily available to the millions of people who wish to see and enjoy them").
We think it also apparent that the city's interest in ensuring the sufficiency of sound amplification at bandshell events is a substantial one. The record indicates that inadequate sound amplification has had an adverse affect on the ability of some audiences to hear and enjoy performances at the bandshell. The city enjoys a substantial interest in ensuring the ability of its citizens to enjoy whatever benefits the city parks have to offer, from amplified music to silent meditation. See Community for Creative Non-Violence , supra, at 296.
The Court of Appeals recognized the city's substantial interest in limiting the sound emanating from the bandshell. See 848 F.2d, at 370. The court concluded, however, that the city's sound-amplification guideline was not narrowly tailored to further this interest, because "it has not [been] shown . . . that the requirement of the use of the city's sound system and technician was the least intrusive means of regulating the volume." Id., at 371 (emphasis added). In the court's judgment, there were several alternative methods of achieving the desired end that would have been less restrictive of respondent's First Amendment rights.
The Court of Appeals erred in sifting through all the available or imagined alternative means of regulating sound volume in order to determine whether the city's solution was "the least intrusive means" of achieving the desired end. This "less-restrictive-alternative analysis . . . has never been a part of the inquiry into the validity of a time, place, and manner regulation." Regan v. Time, Inc. , 468 U.S. 641, 657 (1984) (opinion of White, J.). Instead, our cases quite clearly hold that restrictions on the time, place, or manner of protected speech are not invalid "simply because there is some imaginable alternative that might be less burdensome on speech." United States v. Albertini , 472 U.S. 675, 689 (1985).
"We are unmoved by the Court of Appeals' view that the challenged regulation is unnecessary, and hence invalid, because there are less speech-restrictive alternatives that could have satisfied the Government interest in preserving park lands. . . . We do not believe . . . that either United States v. O'Brien or the time, place, or manner decisions assign to the judiciary the authority to replace the [parks department] as the manager of the [city's] parks or endow the judiciary with the competence to Judge how much protection of park lands is wise and how that level of conservation is to be attained." 468 U.S., at 299.
Lest any confusion on the point remain, we reaffirm today that a regulation of the time, place, or manner of protected speech must be narrowly tailored to serve the government's legitimate, content-neutral interests but that it need not be the least restrictive or least intrusive means of doing so.6 Rather, the requirement of narrow tailoring is satisfied "so long as the . . . regulation promotes a substantial government interest that would be achieved less effectively absent the regulation." United States v. Albertini , supra, at 689; see also Community for Creative Non-Violence , supra, at 297. To be sure, this standard does not mean that a time, place, or manner regulation may burden substantially more speech than is necessary to further the government's legitimate interests. Government may not regulate expression in such a manner that a substantial portion of the burden on speech does not serve to advance its goals.7 See Frisby v. Schultz , 487 U.S., at 485 ("A complete ban can be narrowly tailored but only if each activity within the proscription's scope is an appropriately targeted evil"). So long as the means chosen are not substantially broader than necessary to achieve the government's interest, however, the regulation will not be invalid simply because a court concludes that the government's interest could be adequately served by some less-speech-restrictive alternative. "The validity of [time, place, or manner] regulations does not turn on a Judge's agreement with the responsible decisionmaker concerning the most appropriate method for promoting significant government interests" or the degree to which those interests should be promoted. United States v. Albertini , 472 U.S., at 689; see Community for Creative Non-Violence , supra, at 299.
It is undeniable that the city's substantial interest in limiting sound volume is served in a direct and effective way by the requirement that the city's sound technician control the mixing board during performances. Absent this requirement, the city's interest would have been served less well, as is evidenced by the complaints about excessive volume generated by respondent's past concerts. The alternative regulatory methods hypothesized by the Court of Appeals reflect nothing more than a disagreement with the city over how much control of volume is appropriate or how that level of control is to be achieved. See Community for Creative Non-Violence , supra, at 299. The Court of Appeals erred in failing to defer to the city's reasonable determination that its interest in controlling volume would be best served by requiring bandshell performers to utilize the city's sound technician.
The city's second content-neutral justification for the guideline, that of ensuring "that the sound amplification [is] sufficient to reach all listeners within the defined concert-ground," 658 F. Supp., at 1352, also supports the city's choice of regulatory methods. By providing competent sound technicians and adequate amplification equipment, the city eliminated the problems of inexperienced technicians and insufficient sound volume that had plagued some bandshell performers in the past. No doubt this concern is not applicable to respondent's concerts, which apparently were characterized by more-than-adequate sound amplification. But that fact is beside the point, for the validity of the regulation depends on the relation it bears to the overall problem the government seeks to correct, not on the extent to which it furthers the government's interests in an individual case. Here, the regulation's effectiveness must be Judged by considering all the varied groups that use the bandshell, and it is valid so long as the city could reasonably have determined that its interests overall would be served less effectively without the sound-amplification guideline than with it. United States v. Albertini , supra, at 688-689; Community for Creative Non-Violence , 468 U.S., at 296-297. Considering these proffered justifications together, therefore, it is apparent that the guideline directly furthers the city's legitimate governmental interests and that those interests would have been less well served in the absence of the sound-amplification guideline.
Respondent nonetheless argues that the sound-amplification guideline is not narrowly tailored because, by placing control of sound mix in the hands of the city's technician, the guideline sweeps far more broadly than is necessary to further the city's legitimate concern with sound volume. According to respondent, the guideline "targets . . . more than the exact source of the 'evil' it seeks to remedy." Frisby v. Schultz , supra, at 485.
If the city's regulatory scheme had a substantial deleterious effect on the ability of bandshell performers to achieve the quality of sound they desired, respondent's concerns would have considerable force. The District Court found, however, that pursuant to city policy, the city's sound technician "give[s] the sponsor autonomy with respect to the sound mix . . . [and] does all that he can to accommodate the sponsor's desires in those regards." 658 F. Supp., at 1352. The court squarely rejected respondent's claim that the city's "technician is not able properly to implement a sponsor's instructions as to sound quality or mix," finding that "[n]o evidence to that effect was offered at trial; as noted, the evidence is to the contrary." App. to Pet. for Cert. 89. In view of these findings, which were not disturbed by the Court of Appeals, we must conclude that the city's guideline has no material impact on any performer's ability to exercise complete artistic control over sound quality. Since the guideline allows the city to control volume without interfering with the performer's desired sound mix, it is not "substantially broader than necessary" to achieve the city's legitimate ends, City Council of Los Angeles v. Taxpayers for Vincent , 466 U.S., at 808, and thus it satisfies the requirement of narrow tailoring.
The final requirement, that the guideline leave open ample alternative channels of communication, is easily met. Indeed, in this respect the guideline is far less restrictive than regulations we have upheld in other cases, for it does not attempt to ban any particular manner or type of expression at a given place or time. Cf. Frisby , supra, at 482-484; Community for Creative Non-Violence , supra, at 295; Renton v. Playtime Theatres, Inc. , 475 U.S., at 53-54. Rather, the guideline continues to permit expressive activity in the bandshell, and has no effect on the quantity or content of that expression beyond regulating the extent of amplification. That the city's limitations on volume may reduce to some degree the potential audience for respondent's speech is of no consequence, for there has been no showing that the remaining avenues of communication are inadequate. See Taxpayers for Vincent , supra, at 803, and n. 23, 812, and n. 30; Kovacs , 336 U.S., at 88-89 (opinion of Reed, J.).
The majority sets forth the appropriate standard for assessing the constitutionality of the Guidelines. A time, place, and manner regulation of expression must be content neutral, serve a significant government interest, be narrowly tailored to serve that interest, and leave open ample alternative channels of communication. See Frisby v. Schultz , 487 U.S. 474, 481-482 (1988); Perry Education Assn. v. Perry Local Educators' Assn. , 460 U.S. 37, 44 (1983). The Guidelines indisputably are content neutral as they apply to all bandshell users irrespective of the message of their music. App. 375; see Pacific Gas & Electric Co. v. Public Utilities Comm'n of Cal. , 475 U.S. 1, 20 (1985).1 They also serve government's significant interest in limiting loud noise in public places, see Grayned v. Rockford , 408 U.S. 104, 116 (1972), by giving the city exclusive control of all sound equipment.
The Court's past concern for the extent to which a regulation burdens speech more than would a satisfactory alternative is noticeably absent from today's decision. The majority requires only that government show that its interest cannot be served as effectively without the challenged restriction. Ante, at 799. It will be enough, therefore, that the challenged regulation advances the government's interest only in the slightest, for any differential burden on speech that results does not enter the calculus. Despite its protestations to the contrary, the majority thus has abandoned the requirement that restrictions on speech be narrowly tailored in any ordinary use of the phrase.4 Indeed, after today's decision, a city could claim that bans on handbill distribution or on door-to-door solicitation are the most effective means of avoiding littering and fraud, or that a ban on loudspeakers and radios in a public park is the most effective means of avoiding loud noise. Logically extended, the majority's analysis would permit such far-reaching restrictions on speech.
True, the majority states that "[g]overnment may not regulate expression in such a manner that a substantial portion of the burden on speech does not serve to advance its goals." Ibid. But this means that only those regulations that "engage in the gratuitous inhibition of expression" will be invalidated. Ely, Flag Desecration: A Case Study in the Roles of Categorization and Balancing in First Amendment Analysis, 88 Harv. L. Rev. 1482, 1485 (1975). Moreover, the majority has robbed courts of the necessary analytic tools to make even this limited inquiry. The Court of Appeals examined "how much control of volume is appropriate [and] how that level of control is to be achieved," ante, at 800, but the majority admonishes that court for doing so, stating that it should have "defer[red] to the city's reasonable determination." Ibid. The majority thus instructs courts to refrain from examining how much speech may be restricted to serve an asserted interest and how that level of restriction is to be achieved. If a court cannot engage in such inquiries, I am at a loss to understand how a court can ascertain whether the government has adopted a regulation that burdens substantially more speech than is necessary.
By holding that the Guidelines are valid time, place, and manner restrictions, notwithstanding the availability of less intrusive but effective means of controlling volume, the majority deprives the narrow tailoring requirement of all meaning.6 Today, the majority enshrines efficacy but sacrifices free speech.
The majority's Conclusion that the city's exclusive control of sound equipment is constitutional is deeply troubling for another reason. It places the Court's imprimatur on a quintessential prior restraint, incompatible with fundamental First Amendment values. See Near v. Minnesota ex rel. Olson , 283 U.S. 697 (1931). Indeed, just as "[m]usic is one of the oldest forms of human expression," ante, at 790, the city's regulation is one of the oldest forms of speech repression. In 16th- and 17th-century England, government controlled speech through its monopoly on printing presses. See L. Levy, Emergence of a Free Press 6 (1985). Here, the city controls the volume and mix of sound through its monopoly on sound equipment. In both situations, government's exclusive control of the means of communication enables public officials to censor speech in advance of its expression. See Southeastern Promotions, Ltd. v. Conrad , 420 U.S. 546, 553 (1975). Under more familiar prior restraints, government officials censor speech "by a simple stroke of the pen," Emerson, The Doctrine of Prior Restraint, 20 Law & Contemp. Prob. 648, 657 (1955). Here, it is done by a single turn of a knob.
The majority's implication that government control of sound equipment is not a prior restraint because city officials do not "enjoy unguided discretion to deny the right to speak altogether," ante, at 794, is startling. In the majority's view, this case involves a question of "different and lesser" magnitude -- the discretion to provide inadequate sound for performers. But whether the city denies a performer a bandshell permit or grants the permit and then silences or distorts the performer's music, the result is the same -- the city censors speech. In the words of Chief Justice Rehnquist, the First Amendment means little if it permits government to "allo[w] a speaker in a public hall to express his views while denying him the use of an amplifying system." FEC v. National Conservative Political Action Committee , 470 U.S. 480, 493 (1985); see also Southeastern Promotions , supra, at 556, n. 8 ("A licensing system need not effect total suppression in order to create a prior restraint").
As a system of prior restraint, the Guidelines are presumptively invalid. See Southeastern Promotions , supra, at 558; Bantam Books, Inc. v. Sullivan , 372 U.S. 58, 70 (1963). They may be constitutional only if accompanied by the procedural safeguards necessary "to obviate the dangers of a censorship system." Freedman v. Maryland , 380 U.S. 51, 58 (1965). The city must establish neutral criteria embodied in "narrowly drawn, reasonable and definite standards," in order to ensure that discretion is not exercised based on the content of speech. Niemotko v. Maryland , 340 U.S. 268, 271 (1951); see also Lakewood v. Plain Dealer Publishing Co. , 486 U.S., 750, 758 (1988); Shuttlesworth v. Birmingham , 394 U.S. 147, 150-151 (1969). Moreover, there must be "an almost immediate judicial determination" that the restricted material was unprotected by the First Amendment. Bantam Books, supra, at 70; see also Southeastern Promotions , supra, at 560.
The Guidelines contain neither of these procedural safeguards. First, there are no "narrowly drawn, reasonable and definite standards" guiding the hands of the city's sound technician as he mixes the sound. The Guidelines state that the goals are "to provide the best sound for all events" and to "insure appropriate sound quality balanced with respect for nearby residential neighbors and the mayorally decreed quiet zone." App. 375; see also ante, at 794. But the city never defines "best sound" or "appropriate sound quality." The bandshell program director-manager testified that quality of sound refers to tone and to sound mix. App. 229, 230. Yet questions of tone and mix cannot be separated from musical expression as a whole. See The New Grove Dictionary of Music and Musicians 51-55 (S. Sadie ed. 1980) (tonality involves relationship between pitches and harmony); F. Everest, Successful Sound System Operation 173 (1985) ("The mixing console . . . must be considered as a creative tool"). Because judgments that sounds are too loud, noiselike, or discordant can mask disapproval of the music itself,7 government control of the sound-mixing equipment necessitates detailed and neutral standards.
Second, even if there were narrowly drawn guidelines limiting the city's discretion, the Guidelines would be fundamentally flawed. For the requirement that there be detailed standards is of value only so far as there is a judicial mechanism to enforce them. Here, that necessary safeguard is absent. The city's sound technician consults with the performers for several minutes before the performance and then decides how to present each song or piece of music. During the performance itself, the technician makes hundreds of decisions affecting the mix and volume of sound. Tr. of Oral Arg. 13. The music is played immediately after each decision. There is, of course, no time for appeal in the middle of a song. As a result, no court ever determines that a particular restraint on speech is necessary. The city's admission that it does not impose sanctions on violations of its general sound ordinance because the necessary litigation is too costly and time consuming only underscores its contempt for the need for judicial review of restrictions on speech. Id., at 5. With neither prompt judicial review nor detailed and neutral standards fettering the city's discretion to restrict protected speech, the Guidelines constitute a quintessential, and unconstitutional, prior restraint.
"To provide the best sound for all events Department of Parks and Recreation has leased a sound amplification system designed for the specific demands of the Central Park Bandshell. To insure appropriate sound quality balanced with respect for nearby residential neighbors and the mayorally decreed quiet zone of Sheep Meadow, all sponsors may use only the Department of Parks and Recreation sound system. DEPARTMENT OF PARKS AND RECREATION IS TO BE THE SOLE AND ONLY PROVIDER OF SOUND AMPLIFICATION, INCLUDING THOUGH NOT LIMITED TO AMPLIFIERS, SPEAKERS, MONITORS, MICROPHONES, AND PROCESSORS.
6. Respondent contends that our decision last term in Boos v. Barry , 485 U.S. 312 (1988), supports the Conclusion that "a regulation is neither precisely drawn nor 'narrowly tailored' if less intrusive means than those employed are available." Brief for Respondent 27. In Boos we concluded that the government regulation at issue was "not narrowly tailored; a less restrictive alternative is readily available." 485 U.S., at 329 (citing Wygant v. Jackson Bd. of Ed. , 476 U.S. 267, 280, n. 6 (1986) (plurality opinion)). In placing reliance on Boos , however, respondent ignores a crucial difference between that case and this. The regulation we invalidated in Boos was a content-based ban on displaying signs critical of foreign governments; such content-based restrictions on political speech "must be subjected to the most exacting scrutiny." 485 U.S., at 321. While time, place, or manner regulations must also be "narrowly tailored" in order to survive First Amendment challenge, we have never applied strict scrutiny in this context. As a result, the same degree of tailoring is not required of these regulations, and least-restrictive-alternative analysis is wholly out of place. For the same reason, the Dissent's citation of Richmond v. J. A. Croson Co. , 488 U.S. 469 (1989), is beside the point. See post, at 806, n. 4. Croson , like Boos , is a strict-scrutiny case; even the Dissent does not argue that strict scrutiny is applicable to time, place, or manner regulations.
