I already had a modest amount of high-frequency hearing loss before a car accident earlier this year impaired my hearing further.

One peculiar result of the accident was that, suddenly, certain high-frequency notes in music were bumped up one or two notes in pitch, of all things. I.e., I might hear a high C as the D or E above it on the scale. So, it's not that I can't hear the note; I hear it as the wrong note. Obviously, this ruins Del Shannon's "Runaway" for me ... and many other songs.

And, of course, the standard audiologist, trying to help people hear voices better, has no hearing test for this problem, has no solution for it, and my complaint was even far, far outside the wheelhouse of the ENT specialist I saw.

In addition, the ENT specialist had no idea where to send me for help with this.

Can anyone suggest a way to find a doctor (or institution) that would understand this problem and have some idea what to do about it?

Thanks.
