@eclectic It is all the time yes! The pitch in my right ear is higher. If I play a 440 Hz sine wave in my hearing aids for both my ears, my right ear has a distorted sine wave and it sounds like a rapid change in pitch going up and down I guess?
If I do a square wave, I think it goes up an entire note on my right ear.
@eclectic I guess for my right ear, I guess it is called a beat or something? Like the sine wave on my right ear has binaural beats.
But I am not an audio engineer and I do not know much about audio.
