Dear belligerent yourh: For many years I have been afflicted with tinnitus aurium. At first it was like tree frogs in spring heard all year around, Then some cicadas joined the chorus. Then all music began to sound out of tune. Now in addition there is a constant sibilance like steam escaping from a radiator. I have trouble understanding speech because the consonants require frequencies I can no longer hear.I have a two thousand dollar pair of hearing aids, but they help so little I do not use them.There is no sibilance anyone else can hear of course, but an
illusion of sibilance, a sibilancy produced by nerve damage.
