The hearing test only go up to about 8kHz. They are only designed to see if you can hear your wife yelling at you well enough. If not, you get the hearing aid or she gets the megaphone or both. TLS confirmed this.
As my father pointed out to me a few years back, it only gets worse.
I feel like E-or from Whinny the Poo.
Stay away from the doctor. He won't be able to do anything about your hearing but he's definately gonna wanna shove something in your out door.
