Sorry to hear that Torqdog. What kind of tests did the audiologist run, and how were the dips measured?
I don't think I have any significant hearing loss, but this thread had gotten me curious. I don't ever listen very loudly, or do anything that is harmful to my hearing, but I sometimes get high frequency ringing in my ears, and as far as I can remember, it has always happened. It's not really set off by loud volumes, because it randomly happens when it's dead quiet too. Basically, I got a sensation where the background noise of the room just drops (like I'm losing all hearing) for a split second, following by faint high frequency ringing that lasts for maybe 30 seconds. Is this some form of tinnitus?
I ran some long sweeps with REW just to see if my ears have gaps at certain frequencies. I know that this won't give any reliable results, but I just wanted to get an idea. I tried headphones and different speaker systems, and overall, I feel like I'm pretty flat from 200Hz-8kHz. After 8kHz, it starts rolling off until 15kHz, where I can't hear a -10dbFS tone above the room noise. With headphones, I can make out a 17kHz tone, but it is very faint.
I'm 26, by the way, and some high frequency hearing loss is expected at my age. However, is the roll off starting at 8kHz pretty common for everybody? I know that the only way to get actual answers is to see an audiologist, but at this point, I'm don't think anything is wrong with me. I'm just curious if my experience is similar to what other people experience.
