I want to measure sound in a air/gas chamber (2m X 2mX 2m) which will be kept underwater. So I want to measure sound underwater by keeping a air/gas chamber underwater. The gas chamber will have a microphone or a suitable sound sensor that works in air/gas. Which material will I have to use to carry the sound from water into the air/chamber so that my microphone picks up the sound.
Thanks in advance.

It will have to be very strong, since your enclosure is large and cubical. That trumps most discussion of acoustics. On the acoustics side, making it out of a single rigid material will reduce the absorption and scattering of sound.

It's just good Netiquette. Failing that, Chlorpromazine.
