The thing with audiograms is that a lot of things can influence their results. You can see how
@Ed209 's results between two tests differ significantly:

Speaking for myself, the three audiograms I've had done this year have wildly fluctuated within a 5-10 dB range. The first audiogram I got showed a 15 dB threshold near 3 kHz with a jagged pattern from 250 Hz to 8 kHz. When I had it done again recently, it was a straight line through 5 dB for all frequencies. Many factors impact your audiogram, such as the presence of wax, anxiety, stress, the equipment used, the tests performed, the frequencies tested, and many else. Your audiologist will treat anything <25 dB as normal though, so you could hypothetically drop from 0 to 15 dB in one frequency, which would be noticeable to you, and your audiologist will still think your hearing is normal if you don't have a previous audiogram to compare with. I felt like
@dpdx did immediately after my tinnitus appeared, music sounded flat, distorted, and hollow for some reason, but when I had my hearing tested the audiologist said it was normal. If you feel your hearing isn't as good, you have hearing loss for whatever reason, simple as that. Audiograms are much too imprecise for people whose hearing aren't severely impaired.
