I noticed something that disturbed me. I thought that the right ear where my hearing damage shows in the audiogram also is the ear that causes my hyperacusis. Today I was in a noisy environment and decided to protect my right ear and listen with my "healthy" left ear. Now I find that the noise that entered my left ear also has disturbed my right ear. Could it be that the process that regulates the amplification of the cochlea (outer hair cells) on my right ear are also responding to noise entering the other ear? I believe so. Earlier I noticed that when I protect my right ear and a sharp sound (plate or cup) enters my left ear I hear something uncomfortable in my right ear. Sometimes audible, sometimes a feeling. I just want to say that if you think about protecting only one ear this could not be enough. Now I have distortion in both ears. I hope this soon will abate.
