The immediate answer I want to give is of course. But then here I sit with no information to back it up, haha! I just know that we don't hear the entire range of pitch that is created by the music we listen to. I think that's the reason why different age groups like different music, aside from plain personal preference, because it sounds different depending on your age.Well I was thinking about something similar. Does our music produce sounds in frequencies we can't hear that could disturb animals?
