                Synopsis
                I. NPRM
                1. In this Notice of Proposed Rulemaking, the Commission proposes to incorporate by reference a new 2019 ANSI Standard (ANSI C63.192019, American National Standard Methods of Measurement of Compatibility Between Wireless Communication Devices and Hearing Aids, August 19, 2019 (2019 ANSI standard)) into its rules and to make it the exclusive testing standard for determining hearing aid compatibility after a two-year transition. The Commission's rules presently incorporate by reference the 2007 version of this standard (ANSI C63.192007, American National Standard Methods of Measurement of Compatibility Between Wireless Communication Devices and Hearing Aids, June 8, 2007 (2007 ANSI standard)) and the 2011 version of this standard (ANSI C63.192011, American National Standard Methods of Measurement of Compatibility Between Wireless Communication Devices and Hearing Aids, May 27, 2011 (2011 ANSI standard)). In addition, to incorporating by reference the 2019 ANSI standard, the Commission proposes to extend a volume control deadline until the start of the exclusive use of the 2019 ANSI Standard. Finally, the Commission proposes to remove unnecessary or superseded rule provisions and seeks comment on ways to simplify and update the hearing aid compatibility rules.
                A. Codification of the 2019 ANSI Standard
                2. Consistent with past practice, the Commission proposes to incorporate by reference the 2019 ANSI Standard into its rules as the exclusive technical standard for evaluating the hearing aid compatibility of wireless handsets. The Commission has long recognized that its hearing aid compatibility rules should evolve as revisions to ANSI standards are developed over time. To this end, the Commission has encouraged the ANSI Committee to periodically work with relevant stakeholders to review hearing aid compatibility issues and determine whether improvements to the standard are warranted. Accordingly, the Commission proposes to amend its rules to use the 2019 ANSI standard as the exclusive standard for determining hearing aid compatibility after the expiration of a two-year transition period. After the expiration of the transition period, new handsets models would have to be certified under this standard as hearing aid-compatible in order for manufacturers and service providers to use these new handsets to meet their handset deployment requirements.
                
                    3. The Commission anticipates that using the 2019 ANSI standard to determine whether a handset is hearing aid-compatible for purposes of its rules will serve the public interest by establishing standards for new devices and operations over additional frequency bands. The 2019 ANSI standard includes volume control metrics for the first time, and covers newer technologies and devices operating in the frequency range of 614 MHz to 6 GHz, as compared to the 2011 ANSI standard's frequency range of 698 MHz to 6 GHz. New testing methodologies in the 2019 ANSI standard should also improve the measurement of potential hearing aid 
                    
                    interference. The new standard no longer uses the M/T category system, achieves harmonization with hearing aid standards that apply to other types of equipment, and changes several testing procedures meant to improve the consumer experience and reduce testing burdens.
                
                4. If the Commission adopts the 2019 ANSI standard, it proposes to treat handsets operating over multiple frequency bands or air interfaces in the same manner as under its current rules. That is, a handset operating only in the ranges specified in the 2019 ANSI standard would be required to satisfy that standard for all frequency bands and air interfaces over which it operates. But if a handset also operates in frequency ranges not addressed by the 2019 ANSI standard, it would be considered hearing aid-compatible as long as it satisfies the 2019 ANSI Standard for those frequencies covered by the standard.
                5. The Commission seeks comment on its proposal to adopt the 2019 ANSI standard. Do commenters agree that the new standard is consistent with the requirement that handsets produce sound levels suitable for persons with hearing loss (including persons with and without hearing aids), would improve the measurement of potential hearing aid interference, and would reduce the testing burden? Would adoption of the standard impose costs on manufacturers or service providers that are reasonable in light of its benefits?
                6. The Commission recognizes that the 2019 ANSI standard does not cover frequencies above 6 GHz, as the higher millimeter wave frequencies were not commonly used in mobile handsets at the time the standard was being developed. The Commission therefore takes this opportunity to fulfill its statutory obligation to assess whether to continue to exempt handsets operating in frequencies above 6 GHz from the statutory hearing aid compatibility requirements. Section 710 of the Communications Act of 1934, as amended, exempts telephones used with public mobile services from the hearing aid compatibility requirements but directs the Commission to assess periodically the appropriateness of continuing in effect those exemptions. The Commission has partially revoked the statutory exemption for wireless handsets operating below 6 GHz, but has not had occasion to assess the exemption recently for handsets operating above 6 GHz. Accordingly, the Commission seeks comment generally on whether to continue to exempt handsets operating with frequencies above 6 GHz from the hearing aid compatibility requirements. What is the effect, if any, on hearing aid users from mobile handset operations in the mmW frequencies? What is the impact on individuals with hearing loss of excluding frequencies above 6 GHz from the compatibility requirements? As a practical matter, do higher frequencies pose the same interference concerns as the lower frequencies for hearing aids? Is compliance with the hearing aid compatibility standards technologically feasible for devices operating over 6 GHz? What would be the additional cost of testing in higher frequencies used by 5G? Would these additional costs limit innovation for handsets operating in the higher frequencies?
                
                    7. As indicated above, the 2019 ANSI standard revises how hearing aid compatibility is determined between wireless handsets and hearing aids and, for the first time, requires handsets to meet a volume control requirement in order to be considered hearing aid-compatible under that standard. The new standard specifies testing procedures for new technologies and devices operating in the frequency range of 614 MHz to 6 GHz and replaces the present numerical M/T rating system with a simple set of requirements and thresholds. As a result of these changes, the new standard will improve the experience of hearing aid users, including those who use cochlear implants, while at the same time reducing testing burdens. The standard is available for inspection at the Federal Communications Commission (FCC), 445 12th St. SW, Reference Information Center, Room CYA257, Washington, DC 20554, (202) 4180270. The standard is available for purchase from IEEE Operations Center, 445 Hoes Lane, Piscataway, NJ 088544141, by calling (732) 9810060, or going to 
                    https://standards.ieee.org/.
                
                B. Transition Period
                
                    8. In its filing, the ANSI Committee urges the Commission to adopt an appropriate transition period for implementing the new standard, but it does not recommend a particular length of time. The Commission agrees that manufacturers and service providers will likely require some transition period in order to design, manufacture, and market equipment that satisfies the 2019 ANSI Standard for hearing aid compatibility, and the Commission seeks comment on how much time is reasonably needed. The Commission proposes to phase out the 2011 ANSI standard over a transition period of two (2) years from the date the order adopting the 2019 ANSI standard is published in the 
                    Federal Register
                    . The Commission used a two-year transition period before making the 2007 ANSI standard the exclusive testing standard for hearing aid compatibility and a two-year transition period before requiring the 2011 ANSI standard be used for meeting hearing aid compatibility requirements for newly covered frequency bands and air interfaces that were not covered by the 2007 ANSI standard. The Commission proposes a similar two-year transition period to appropriately balance the design, engineering, and marketing requirements of manufacturers and service providers with the needs of consumers with hearing loss.
                
                9. In assessing its proposed two-year transition period, the Commission seeks comment on the steps manufacturers must take to implement the 2019 ANSI standard and their implications for the length of the transition period. What is the scope and timeline of the design changes necessary to incorporate the 2019 ANSI standard into future handsets? Commenters should consider manufacturers' product fabrication cycles and the practicality of testing multi-band or multi-mode handsets in the near-term under the 2019 ANSI standard. Are there multi-band or multi-mode handsets planned for near-term introduction that meet the hearing aid compatibility criteria for their operations covered under the 2011 ANSI standard but do not meet those criteria for newly covered operations or revised testing procedures under the 2019 ANSI standard? What, if any, obstacles do manufacturers anticipate facing? Given the clear public interest in moving quickly to make advanced technology available to those with hearing loss, the Commission urges any commenters proposing a transition of longer than two years to provide specific information about why more time is needed.
                
                    10. The Commission further seeks comment on the effect its proposed transition period likely will have on the Commission's ability to decide by 2024 whether to require 100% of covered handsets to be hearing aid-compatible. Does a two-year transition period encourage manufacturers to increase the number of hearing aid-compatible handsets they produce or help them eventually achieve 100% hearing aid-compatibility? Or would the design changes required by the 2019 ANSI standard negatively affect the ability of device manufacturers to meet any requirement the Commission may determine to impose that all covered handsets be hearing aid-compatible by a certain date in the future? Are there any 
                    
                    issues related to the pending 100% proceeding that the Commission should consider with respect to making the 2019 ANSI standard the exclusive testing standard going forward? Commenters should fully explain any relationship between the adoption of the 2019 ANSI standard as the exclusive testing standard and the potential requirement for 100% of handsets to be hearing aid-compatible.
                
                11. Although the Commission proposes to allow a two-year transition period before requiring exclusive use of the 2019 ANSI Standard, including its volume control requirements, it notes that manufacturers currently have a deadline in less than a year-and-a-half to ensure that wireless handsets are equipped with volume control that produces sound levels suitable for persons with hearing loss (including persons with and without hearing aids). The Commission proposes to extend this volume control deadline so that it coincides with the start of the exclusive use of the 2019 ANSI standard. The Commission seeks comment on this proposal. Would retaining disparate deadlines for volume control and exclusive use of the 2019 ANSI standard effectively require manufacturers to develop new handsets to meet the volume control deadline and then develop a new batch of handsets to satisfy the 2019 standard? Commenters should be specific about the costs and benefits of their proposed approach.
                
                    12. Consistent with past transitions to new standards, the Commission proposes permitting new handset models to be tested for certification using 
                    either
                     the 2011 or 2019 ANSI standards during the transition period. Consistent with the 1988 Hearing Aid Compatibility Act and the current rules, the Commission proposes that all existing hearing aid compatibility certifications issued prior to and within the transition period, including certifications under the 2011 ANSI standard as well as any earlier versions of the standard, would remain valid. As a result, no existing handset models would need to be retested or recertified as hearing aid-compatible. The Commission seeks comment on this approach.
                
                13. The Commission notes that the Commission's existing handset certification procedures do not permit a handset model to be tested and certified partly under one version of the ANSI standard and partly under another. The Commission has taken this approach because each ANSI standard has its own complete set of testing procedures and mixing these procedures will result in a meaningless outcome. Consistent with this long-established certification practice, the Commission proposes that manufacturers continue to be required to test a new handset model exclusively under either the 2011 ANSI standard or the 2019 ANSI standard during the transition period. After the end of the transition period, the Commission proposes that new handset models be required to satisfy fully the 2019 ANSI standard, including its volume control requirements, for all of the frequency bands covered by the standard to be considered hearing aid-compatible. The Commission seeks comment on this proposal.
                C. Meeting Deployment Benchmarks
                14. Subject to a de minimis exception, handset manufacturers and service providers must offer minimum numbers of hearing aid-compatible handset models for each covered air interface over which its handsets operate. Depending on the type and size of an entity and the point in time, manufacturers and providers will need to ensure that either 66% or 85% of their handset models are hearing aid-compatible. Under the 2011 ANSI standard, this means that a handset must be rated M3 or higher and T3 or higher for any given air interface. With respect to the 2019 ANSI standard, for the handset to be hearing aid-compatible over a covered air interface, the handset must meet the requirements for both acoustic and inductive coupling modes for that air interface, including the volume control requirements.
                
                    15. If the Commission adopts the 2019 ANSI standard going forward, it proposes to allow manufacturers and service providers to meet the requirement to offer minimum numbers of hearing aid-compatible handsets by counting the models certified under the 2019 ANSI standard and handset models already certified under earlier versions of the standard (
                    i.e.,
                     the 2007 and 2011 versions of the standard) as long as those models are still being offered for sale. As more and more handset models become certified under the 2019 ANSI standard, the Commission expects that handset models certified under older versions of the ANSI standard will cease being offered for sale and will be replaced with new models certified under the 2019 ANSI standard. Manufacturers and national wireless providers are already required to ensure that 66% of the handsets they offer are hearing aid-compatible, and the Commission expects handsets meeting the 2019 ANSI standard to be common within a few years after the end of the transition period. The Commission also notes that, while manufacturers would not be required to certify their new handset models under the 2019 ANSI standard during the transition period in order to meet their minimum deployment benchmarks, they may find using the 2019 standard advantageous from a marketing perspective. The Commission seeks comment on this proposal. What are the costs and benefits to device manufacturers, service providers, and consumers with hearing loss of allowing handsets certified under previous ANSI standards to count toward the minimum number of hearing aid-compatible handsets that must be offered? Are there reasons to impose new requirements on manufacturers and service providers to offer minimum numbers of handsets certified to comply with the 2019 ANSI standard?
                
                D. Labeling Requirements
                16. The Commission proposes to update and modernize its hearing aid compatibility labeling requirements in order to eliminate outdated provisions and to streamline and clarify these requirements. The 1988 Hearing Aid Compatibility Act provides that the Commission shall establish . . . requirements for the labeling of packaging materials . . . to provide adequate information to consumers on the compatibility between telephones and hearing aids. This Congressional directive requires us to ensure that consumers have sufficient information to make an informed decision when selecting hearing aid-compatible handsets. Given this directive, the Commission proposes to simplify its current hearing aid compatibility labeling requirements so that consumers will have the easily understandable information they need in order to understand and evaluate the hearing aid compatibility of a particular handset. In making this proposal, the Commission is mindful that its labeling requirements must not only cover new handset models certified under the 2019 ANSI standard but also cover handset models that are still being offered for sale and that have been certified as hearing aid-compatible under older versions of the ANSI standard.
                
                    17. The Commission's current labeling requirements are composed of four parts. The first requires manufacturers and service providers to ensure that a label on the exterior packaging of a wireless handset indicates the M- and T-rating of the handset model under the 2011 ANSI Standard. Under the 2019 ANSI Standard, however, this information would no longer be relevant because the new standard does not use a rating 
                    
                    system. The second part requires manufacturers and service providers to display information on the handset's volume control capabilities. The third part establishes labeling requirements related to handsets that are considered hearing aid-compatible with respect to some, but not all of their frequency bands and air interfaces. The fourth part imposes disclosure requirements relating to handsets that allow users to reduce the maximum power for GSM operation in the 1900 MHz band. This power down exception was eliminated when the Commission adopted the 2011 ANSI standard as the exclusive testing standard.
                
                18. With the objectives of modernizing and streamlining its rules, the Commission proposes to reorganize its existing hearing aid compatibility labeling requirements by requiring the following:
                
                    
                        (1) For all handset models certified to be hearing aid-compatible, manufacturers and service providers shall disclose to consumers through clear and effective means (
                        e.g.,
                         inclusion of packaging materials, user manuals, call-out cards or other physical media):
                    
                    (i) That the handset is hearing aid-compatible (including placing this information on the handset's packaging label);
                    (ii) The air interfaces on the handset that are not hearing aid-compatible, if applicable, or have been determined to be hearing aid-compatible under special testing circumstances;
                    (iii) The ANSI standard that was used to determine the hearing aid compatibility of the handset model's air interfaces; and
                    (iv) If using the 2011 ANSI standard or earlier, the lowest hearing aid compatibility rating assigned to any of the air interfaces.
                    (2) Any handset model certified to be hearing aid-compatible but with one or more air interfaces that are not hearing aid-compatible must include the following language:
                    This phone has been tested and certified for use with hearing aids for some of the wireless technologies that it uses. However, there may be some newer wireless technologies used in this phone that have not been tested yet for use with hearing aids. It is important to try the different features of this phone thoroughly and in different locations, using your hearing aid or cochlear implant, to determine if you hear any interfering noise. Consult your service provider or the manufacturer of this phone for information on hearing aid compatibility. If you have questions about return or exchange policies, consult your service provider or phone retailer.
                    (3) For those handset models that have been certified as having met the 2019 ANSI standard's volume control requirement, manufacturers and service providers must clearly display information indicating the handset's amplification capabilities, including numerical metrics or ratings for handset volume control, on the packaging material of the handset and must also provide an explanation of those capabilities in the handset's user manual or as an insert in the packaging material for the handset. The volume control metrics or ratings displayed shall be the lowest metrics or ratings assigned to the handset for any air interface or frequency band.
                
                
                    19. The Commission proposes to modify its current volume control labeling requirement to delete the pending volume control compliance date and the cross reference currently contained in the rule, and to make implementation of the rule easier for manufacturers and service providers to follow. Given that its current labeling requirement was adopted prior to the volume control technical standard being released as part of the 2019 ANSI Standard, the Commission believes that these changes will provide clarity and aid compliance. The Commission seeks comment on whether its revised volume control labeling requirement will provide consumers with sufficient information to make an informed decision about a handset's volume control capabilities. If more information is required, the Commission seeks comment on what additional information is needed, why, and where that information should be displayed (
                    e.g.,
                     label, package insert, or user manual).
                
                20. More generally the Commission seeks comment on whether its proposed revised labeling and disclosure requirements are straightforward and conspicuous enough for consumers to understand the hearing aid compatibility of a particular handset model. Does its proposal take into consideration the information that a consumer needs to know to make an informed decision both with respect to handset models certified under the 2019 ANSI standard and those that are still being offered for sale that have been certified under older versions of the standard? Is there any additional information that consumers should be informed of when considering hearing aid-compatible handsets? Consistent with the existing labeling rule, the Commission's proposal requires manufacturers and service providers to disclose on a handset's packaging label if the handset is hearing aid-compatible and additional information on the handset's packaging label if the handset meets the volume control requirement. Further, consistent with the existing labeling requirement, the Commission's proposal requires manufacturers and service providers to disclose other hearing aid compatibility information through clear and effective means such as packaging labels, user manuals and instructions, call-out cards or other appropriate media. Are these methods of disclosure sufficient to meet consumer needs? What, if any, additional information should be required and where should this information be displayed? The Commission also seeks comment on whether it should continue to require service providers to make handsets available for in-store testing by consumers and whether a transition period is needed before its proposed new labeling requirements become effective.
                E. Other Rule Changes
                
                    21. 
                    Section 20.19.
                     The Commission seeks comment on whether to revise certain other provisions in section 20.19 to streamline and update its hearing aid compatibility requirements.
                
                
                    21. With the rapid pace of handset development and the number of new handsets that come to market each year, the Commission proposes to delete the refresh and differing levels of functionality requirements contained in the Commission's hearing aid compatibility rules. These requirements require manufacturers and service providers to refresh and offer a range of hearing aid-compatible handset models that include a mix of new and existing models. The Commission seeks comment about whether these requirements remain necessary as more and more handsets are required to be hearing aid-compatible. The Commission's current handset deployment benchmarks require 66% of offered handset models to be hearing aid-compatible and these benchmarks increase to 85% in the near future. Given that these benchmarks require a significant majority of handsets to be hearing aid-compatible, are the refresh and differing levels of functionality requirements still necessary to ensure consumers have a wide variety of hearing aid-compatible handsets from which to choose? Have the Commission's changes to the handset deployment benchmarks rendered these requirements unnecessary? Commenters should address the costs and benefits to manufacturers, service providers, and consumers with hearing loss if the Commission eliminates these requirements. The Commission further proposes to make a corresponding change to section 20.19(h) and delete the requirement that service providers make available on their websites information about the differing levels of functionality of each handset they 
                    
                    offer. The Commission seeks comment on its proposal.
                
                23. The Commission proposes to revise the date that service providers must file certifications of compliance with the Commission's hearing aid compatibility provisions and the date that manufacturers must file compliance reports. Presently, service provider certifications are due January 15 each year and manufacturer reports are due July 15 each year. The Commission proposes to move these dates to January 31 and July 31, respectively. Under this approach, the filing window for service providers would open the first business day in January and for manufacturers the first business day in July. This change would ensure that service provider certifications and manufacturer reports are up-to-date as of the last day of the calendar month preceding the due date of each report and certification. The Commission seeks comment on this change.
                24. Finally, throughout section 20.19, the Commission proposes to delete references to implementation dates and benchmarks that have already passed. Eliminating these references will simplify the rules and make them easier to read and understand. The Commission also propose deleting all references to hearing aid compatibility requirements and deployment benchmarks that applied to handsets certified under the 2007 ANSI standard, except for labeling and disclosure requirements related to these handsets. Because all certifications under the 2007 ANSI standard remain valid, current language in the rule describing the requirements and benchmarks that apply to these handsets appears unnecessary. To the extent handsets certified under the 2007 ANSI standard are still being offered for sale, however, these handsets must be labeled in a manner consistent with the Commission's labeling and disclosure requirements. The Commission also seek comment on any other ministerial changes to section 20.19 that it should consider as it updates Commission rules.
                
                    25. 
                    Section 68.300.
                     The Commission proposes a technical correction of section 68.300 of the Commission's rules, which requires labeling of hearing aid-compatible telephones. When the Commission amended part 68 of the rules in 2000 to remove various provisions pertaining to registration of terminal equipment connected to the public switched telephone network (PSTN), it appears that a definition of the term permanently affixed, which is relevant to the labeling requirement, was inadvertently deleted. The Commission proposes to restore an updated version of the definition.
                
                26. Under section 68.300(b) of the rules, if a telephone that is approved for connection to the PSTN is hearing aid-compatible, the letters HAC must be permanently affixed to the telephone. Prior to the 2000 amendments, this provision was designated as paragraph (c) of section 68.300, and it referenced a definition of permanently affixed contained in what was then paragraph (b). In 2000, the Commission deleted the existing paragraph (b)including the definition of permanently affixedand renumbered paragraph (c) as paragraph (b). As a result, section 68.300(b) of the rules now refers to a definition that is no longer present in the rule.
                27. Subsequently, in 2017, the Commission adopted hearing aid compatibility rules for telephonic equipment used with advanced communications services (ACS telephonic CPE). These rules include an updated definition of permanently affixed, applicable to the labeling of such equipment as hearing aid-compatible. To ensure that hearing aid compatibility labeling requirements are consistent for both PSTN telephones and advanced telephonic CPE, the Commission proposes to amend section 68.300(b) to include the same definition currently provided in section 68.502(a), as follows:
                
                    Permanently affixed means that the label is etched, engraved, stamped, silkscreened, indelibly printed, or otherwise permanently marked on a permanently attached part of the equipment or on a nameplate of metal, plastic, or other material fastened to the equipment by welding, riveting, or a permanent adhesive. The label must be designed to last the expected lifetime of the equipment in the environment in which the equipment may be operated and must not be readily detachable.
                
                
                    28. Further, the Commission proposes to delete from the paragraph the stated requirement date of April 1, 1997, given that the starting date has passed. Because there are only minor differences between the new and old definitions of permanently affixed, the Commission does not anticipate that these proposed changes will have any significant effect on the current practices of hearing aid compatibility manufacturers or equipment providers. Therefore, the Commission proposes to make this amendment effective in the normal course, 30 days after 
                    Federal Register
                     publication of the amended rule. The Commission seeks comment on these proposed technical corrections and effective date.

                        Delegation of rulemaking authority.
                         (1) The Chief of the Wireless Telecommunications Bureau and the Chief of the Office of Engineering and Technology are delegated authority, by notice-and-comment rulemaking, to issue an order amending this section to the extent necessary to adopt technical standards for additional frequency bands and/or air interfaces upon the establishment of such standards by ANSI Accredited Standards Committee C63, provided that the standards do not impose with respect to such frequency bands or air interfaces materially greater obligations than those imposed on other services subject to this section. Any new obligations on manufacturers and Tier I carriers pursuant to paragraphs (c) through (i) of this section as a result of such standards shall become effective no less than one year after release of the order adopting such standards and any new obligations on other service providers shall become effective no less than 15 months after the release of such order, except that any new obligations on manufacturers and service providers subject to paragraph (e)(1)(ii) of this section shall become effective no less than two years after the release of such order.
                    
                    (2) The Chief of the Wireless Telecommunications Bureau and the Chief of the Office of Engineering and Technology are delegated authority, by notice-and-comment rulemaking if required by statute or otherwise in the public interest, to issue an order amending this section to the extent necessary to approve any version of the technical standards for radio frequency interference, inductive coupling, or volume control adopted subsequently to the 2007 ANSI standard for use in determining whether a wireless handset meets the appropriate rating over frequency bands and air interfaces for which technical standards have previously been adopted either by the Commission or pursuant to paragraph (k)(1) of this section. This delegation is limited to the approval of changes to the technical standards that do not raise major compliance issues. Further, by such approvals, the Chiefs may only permit, and not require, the use of such subsequent versions of the technical standards to establish hearing aid compatibility.
                    
                        (l) The standards required in this section are incorporated by reference into this section with the approval of the Director of the Federal Register under 5 U.S.C. 552(a) and 1 CFR part 51.
