Hearing loss change?

This is bizar. I could have sworn my hearing loss was at 6khz in the right ear only. And it was very spiked, between like 5900 and 6100. Thats why the ENT ordered an MRI since it was 1 sided and so specific. I clearly remember that from the audiological test. This was 1 month ago. I just checked an online tone generator, and my hearing loss seems to be from about 4000 to 5000 hz in both ears. At 6000 i actually hear great. I wonder if I misremembered (likely), or if something fishy is going on with my hearing. My T tones have completely changed as well. From a high pitch to a white noise with sometimes a high tone through it.

I also distinctly remembering doing this exact same tone generator a few weeks ago, and being able to exactly match my T sound at 6khz.

Im picking up my audiological test tomorrow to verify.
