I really doubt that anyones home sees the amout of music/noise that mine does-
My Discus tank is on one side of a wall between it and my husbands music room. In his room is a home theater/stereo system of frightening decibels, plus a huge double bass acoustic drum kit with a billion cymbals as well as an electronic kit and many, many other percussion toys. When he and friends really get going in there with the drums and Metallica DVD's you can literally hear them from down the street.
Every now and then I brave the noise to sit and watch the fish to make sure they aren't being negatively affected- Discus are fairly skittish fish and I'm sure would panic if frightened. I have yet to see them even react to the noise much less be scared by it.
The house itself is simple concrete block construction, and built on a concrete slab with no basement etc. underneath. I suspect that has something to do with it, but do not know for sure.
