If the ear is phase insensitive (Ohm’s Law of acoustics), and you listen on headphones, how can the brain hear a phase inversion on one channel of a stereo signal?
I play bass guitar and practice on stereo headphones. With a split mono signal, it centred exactly between my ears. Experimenting, I inverted one channel, and it turned into surround sound from ear to ear! Of course, on loudspeakers the sound waves would cancel, but not in the brain. It’s not given phase information by the ears. Puzzling. As far as I know, Ohm’s Law is based on the resonance theory of hearing - each hair in the cochlea produces an output at its resonant frequency.
