Howdy, this is my first post! I've started Pro recently and one game gave me a big question.

When Feedback Eliminator plays a higher frequency (using headphones), somewhere from 2.5kHz upward, I noticed a noisy/hissing sound as the sound died down after answering.

I tried this out in my DAW with a sine wave generator, and while the effect isn't as pronounced, anything from around 3k and up would leave this ghostly hissing ringing in my ears for up to half a second after I'd muted it.

Is this headphone distortion, psychoacoustics or something? The higher the frequency, the more noticeable the effect. Doing this experiment, I definitely found that my ears acclimate much faster than I realized - the sound would be constantly changing after just a second or so. So I figure it's something to do with this, I'd certainly like some confirmation though.
