When I listen to the audio with lots of high HIHAT percussion I can hear it perfectly with the right ear, but not with left. When I listen only with left ear then exactly at the time when HIHAT percussion sound appears my ear starts to ring and makes fake sounds instead of me being able to hear the HIHAT percussion. This just points to theory that there is a damage to hearing and that's why the sensitivity and fake sounds. The brain compensates and produces fake sounds. Is that Dysacusis? Edit: Forgot to add that at the same time I experience little pain in the ear.
