How does it compare to an isolation tank?

• SeanLuke 14y ago
  In comparison, isolation tanks are extremely noisy. You got to try an anechoic chamber to believe it. BTW: many universities have one. The one I worked at (BYU, long ago) has this one: http://www.physics.byu.edu/research/acoustics/facilities.aspx http://www.physics.byu.edu/research/acoustics/facilities.asp... http://vimeo.com/15855229 http://vimeo.com/15855229 (a corny advertisement, but shows the room well) http://www.youtube.com/watch?v=0PGF_cGS8ts http://www.youtube.com/watch?v=0PGF_cGS8ts It's a very good facility. Interestingly, I believe the main anechoic chamber used to be an echo chamber!

    Huh, the vimeo one is weird. I'd think we wouldn't be able to hear them talk, let alone move boxes (at around the 1:00 mark).

      Of course you can hear sounds: but you can only hear direct sounds. All reflected sounds are gone. And that's actually a high percentage of the sounds you normally hear. An anechoic chamber is used to test acoustics in an environment with absolutely no reflection (reverb, echo, etc.).
