message: how do I make a soundproof room without using mattresses? they are too punk rawk
:Matresses certainly are not the only thing you could use to soundproof a room. Many companies exist that sell special soundproofing foam that can be inserted within the walls. If your budget is limited, any fabric, when enough is applied, will probably work. Not that I'm an expert in the field, but I do have that advice to offer. 65.43.199.68 13:53, 25 September 2006 (UTC)

message: "Most vibration / sound transfer from a room to the outside occurs through mechanical means."
Are there other means to transfer sound (which is a mechanical wave and by definition it needs a medium) other than mechanical?
The writer meant: mechanical as opposed to sound transfer through air, is how I understood it. 121.247.68.245 (talk) 17:39, 25 January 2008 (UTC)

message: This article needs more about measurement and design. It could use a photo of construction methods for room-within-a-room. There needs to be a decision about the environmental roadway noise mitigation section: does this stay or get merged somewhere else? There needs to be a discussion of the fire danger of some soundproofing materials. The article should mention Wallace Sabine and Hermann von Helmholtz. Binksternet (talk) 19:10, 20 March 2008 (UTC)

message: I've completely cut some material from the section on "Damping", not because it shouldn't be there but because I cannot follow what the author was trying to say.  (Were they trying to say that internally damped drywall is a more effective way of damping low-frequency vibrations?)
Here's the material I've cut:
:Lead and Neoprene do not address the lower, most bothersome low frequency vibrations and can be very difficult to install as well as costly. One commonly used material is internally damped drywall such as QuietRock.
I invite someone to reintroduce the material in a form that's clearer.  Thanks.

replies: text: Thanks for taking that out. AFAIK, there is no specific characteristic that neoprene and lead have which make them unsuitable for LF damping. LF is tough for every material, including QuietRock. I have to guess that the editor adding this was very gung-ho about QuietRock, and was responding to the difference between it and some other standard methods of damping. Without a cite, though, taking it out was the best move. Binksternet (talk) 02:37, 20 January 2010 (UTC)
thread_title:  Need help in improving section on "Damping" 

message: I feel I should justify my deletions here - and not just by 'No citation' !
:Making a sound wave transfer through different layers of material with different densities assists in noise damping. 
Hopefully I've re-added that in clearer form.
:Open-celled foam is not a good sound damper inside of a wall, as the foam is too dense and offers insufficient surface area for sound wave interaction. Improper use of foam tape as a stand-off for paneling can lead to problems with structural compliance enabling resonance of the panel. This process is analogous to a string holding wind-chimes: the string helps the chimes ring by isolating the vibration instead of damping it. Foam tapes may, therefore, be undependable in a soundproofing protocol.
You're describing some complex systems. Maybe they were just badly-designed ! Panel absorbers rely on enabling panels to resonate, then damping the vibration!
Usually mass (density) tends to correlate with good absorption. Likewise open-cell foam has high surface area. Foam tape can be damping rather than compliant. Best not to use resonant panels, and tape behind the anti-nodes? If the physics is self-contradictory, it is best left out - too confusing.
   
:Extruded polystyrene foam (XPS) and expanded polystyrene foam (EPS), commonly used for thermal insulation, are significant conductors of sound. Polystyrene use as a sound damper should be avoided except in applications where moisture resistance and buoyancy is necessary.  
I also removed references to dampness in damping materials (I hate the English language sometimes!) from the heading as being too 'secondary'.
Most studios don't require buoyancy either - are these references to a specific marine application ? Even air is important as a component of composite damping materials. I suspect polystyrene can be useful for 'damping' of surface reflections (eg to conduct sound into a wall by impedance matching or refractive index matching), or under a perforated membrane in damped Helmholtz absorbers.
See Auralex TruTraps Genesis System Q'Fusors - the footnotes reveal they are EPS foam.
Study on Cementitious Sound Absorber with Expanded Polystyrene Waste as Aggregate.
Also note that there are 2 kinds of 'soundproofing' - anechoic chamber or noise abatement - their requirements may be contradictory in some rare cases !

thread_title:  Bold changes ! Polystyrene; moisture; Open-celled [[foam]]  

message: :I've been having slight "second thoughts": maybe 'soundproofing' should be restricted to sound transmission, not reflection ? OTOH echoes will increase the sound level both inside and outside the room. The article could maybe be improved by renaming it to Acoustic treatment - a missing topic pre-linked from Acoustic foam? I'll try to redirect that here ! 'Soundproofing' sounds like an informal, imprecise term.

text: YES! Good! I was about to suggest the same thing. Change it! Acoustic Treatment is what this article should be called. Sound Proofing is under the grader topic of Acoustic Treatment. Sound Proofing specifically regards transmission. Acoustic Treatment includes Sound Proofing, as well as diffusion, absorption, etc. You have my vote to change it!

thread_title:  Rename to [[Acoustic treatment]] ? 

message: There were a couple of times where the article uses the phrase "pretty straight forward" in describing a certain topic (eg: "The use of distance to dissipate sound is straightforward.") 
There is no need to say it is "straightforward". It doesn't help those who are looking the information up, and in fact, if it is "straightforward", why would we need an entry for it? To me, this reads as the author's ego condescending on the reader who "doesn't know the mysterious secret world of sound". Doesn't do any good. I say this be part of the community and coming across such egos often enough. 
Whether or not that was the intention of the author of this phrase, the use of this phrase has no informational value, and perhaps has a little counter-productive value, so I've deleted them.
