Subject: Re: hearing sudden distortion effect From: Sofia Dahl <dr.sofia.dahl@xxxxxxxx> Date: Sun, 2 Oct 2016 08:04:37 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--001a1146fd9e3bb8cd053ddb9aed Content-Type: text/plain; charset=UTF-8 Dear Jim, I have the same distortion on one ear. It first came after I had had a period of intense playing and rehearsals in rock bands and probably due to a slightly disformed earplug. For a long period my ear would distort sounds in the way you describe. Especially when talking on the phone or in a loud milieu I would have to "protect" that ear a bit extra by putting my finger in it to avoid perceiving any distortion. At the time I checked with a hearing doctor who found my hearing good a d said that most likely I had developed a kind of over sensitivity. This was about 15 years ago, and with some time the trouble decreased and disappeared all together (I also got moulded earplugs that I now use in all loud environments) And then, just two weeks ago, I went to an event where cannons were fired and didn't have plugs with me Since then, the distortion is back in the same ear. The positive with the story is that after a period the ear did recover so I hope yours do as well. Best Sofia On 2 Oct 2016 06:24, "James W.
