My Audiogram Today

Ok, here's my audiogram... normal hearing would be at the 0 dB (decibels - it's on a logarithmic scale) line across the board. Negative dB numbers are a good thing, it means you hear better than average. Positive dB numbers are not, as it would require at least that much additional volume to boost/amplify to get to the 0dB line.

Also, 120 dB is near the human pain threshold for ears. So nothing will be boosted more than 120dB, and in most cases, you don't want to be near that number of amplification as it's quite loud. 130 dB is the absolute threshold for pain. It's louder than the club music pounding away from the big speakers in a dance club. That's probably only 100-ish dB.

Left Ear (the better ear) and Right Ear (the worse ear):
