Most birds have pretty sensitive hearing. As to your fish, remember sound travels through water 2x as fast as air. I would venture a guess that the force or "shockwave" for lack of a better term, that is produced by sound through water is stronger than it is through air. Probably not a good idea to Rock out by your aquarium and hip hop and rap at any level is bad for any living thing (I know I'm showing my age).
I can blast my heavy metal and my fish don't care at all!
Once my scissortails even danced!
They are probably used to it.
Once i was tapping a sick beat for like 5 mins before i realized it was on my tank.
They weren't even phased when I added the pleco.
the NET, on the other hand, actually almost killed one of my danios from shock.
scared us both, I guess.
