sound waves a problem?

[canadawest]

I have my 12 gal Eclipse tank (nursery/hospital tank) in my theatre room as well and none of the inhabitants seem to mind. And this is a full fledged 5.1 surround theatre room that isn't very big and can get very loud, not to mention even just stereo music that gets played quite loudly in my house.

Haven't seen any of the inhabitants wearing earplugs yet.

And on a related thread, I seem to remember reading about a study done on just such a topic a year or so back, and it was concluded that sound waves radiating through the air (regardless of volume) were poorly conducted by the water, and as such had very low intensity when measured under water. This seemed contrary to the fact that sound waves produced under water will travel much farther and at higher intensities than sound waves through air.

Not sure where I read this study, but it was very interesting and had diminished my concerns of me creating "noise polution" in my tanks.
