Ok, I'm gonna look him up.

I have only ever been in one sound booth, with 2 different techs.

When the freq. goes over my hearing I get a click.

If it's the sound wave hitting my ear and causing the click as Mac suggested he's probably right. Given the sound pressure of the 'wave' my eardrum moves, but there is nothing in the chain to change that into sound, the chemo killed 'hairs' according to the audiologist.

I can tell you the challenges at first are broad.

First the hearing goes, then the tinnitus replaces it. Along with clicks and pops.
Then the cocoon, paper doesn't rustle, some other stuff does. My gore tex jacket cannot be worn with hearing aids, but they don't make the paper rustle or the bacon sizzle. I have to be careful in the kitchen, I can boil the whistle kettle dry, I'm going to get an automatic off kettle this weekend. No more crickets, cicadas, and lots of birds are out of the question.

The car drives me nuts. I almost want to wear hearing protection even without hearing aids.

When you realize that with an almost vertical slope down in my audio test at 2200hz there is not a lot amplification can do for me. Amplification at the level required picks up all kinds of ambient noises no one wants amplified.

Next appt. I'm going to ask about the max # of db's you can crank the level before it's a lost cause.

The pitch shifting thing is freaky. It baffles my brain. About 1 hour of that and I'm tired right out. I think somepeople can fool their brain, but if you spent a life time playing music, the fact that something comes out wrong makes your brain go sideways. That's my explanation. I know it is to help with sibilance at high freq. but still, it just seems contrived and 'wrong'. Do not listen to music with this setting! Pitch shifting is ok if you do the whole spectrum, and might be neat if you could drop about 8 semitones, giving women men's voices. That would be odd.
