First off, I'm new here so I'll do a brief introduction: I've never taken a physics class, but am taking AP Physics next year (didn't know they offered it at my high school). I'm also a musician and wannabe engineer, so I'm really interested in sound properties, acoustics, etc. So that's me. Anyways . . . If I wanted to physically invert a sound wave, how would I do that? I saw someone said to just connect a speaker in reverse (+ to - and - to +), but couldn't find any confirmation on that. Also, how would one go about finding the distance required to create deconstructive interference? I'm basically seeing if I can capture any given sound or melody and mute it (or reduce its volume) by playing it back with an inverted sound wave to create deconstructive interference.
