I wont go on about why but does anyone know of an online hearing test which you dont have to sign in for, and that goes beyond 8khz? All the ones i've Googled for won't go very high. i.e. i can hear them with both ears. My GP says my ears are clear and it's my age/what i did in my youth, the usual reasons. did the usual click fingers, wrist watch tick, said i'm o.k. But said slight loss in one ear is normally hard for someone to detect. i told him i noticed it first with my new headphones, turned them around as i thought they were faulty and my left ear still couldn't hear what my right ear could. So all i want is a test to hear the difference between ears, and to see if it gets worse. cheers.
