Subject: Re: hearing sudden distortion effect From: Miriam Kolar <kolar@xxxxxxxx> Date: Mon, 3 Oct 2016 14:21:59 -0600 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Hi Jim, Another anecdote that may be useful . . . My father, a liturgical organist and music director, describes a similar problem in one ear (like a "distorted signal with reverberation") that was first triggered in his mid 60's during a loud choir rehearsal and persisted over many months . . . he says it correlated with a period of regular ibuprofen use, and so he now instead uses naproxen if he needs an NSAID, to avoid the aural distortion effect.
