Might be useful to explore what sounds the child finds intolerant.
One of the first cases I had of intolernace to sound is a good example.
The child and parent reported a tolernace problem - hypersensitivity.
By history the child did not mind a balloon breaking, fireworks, or band
music. The child was bothered by the vacuum cleaner or the mother's
loud (read angry) voice. This case was best referred to a mental health
specialist or family counselor.
There was a presentation on hyperacusis at last AAA. Did have a chance
to attend. You might wish to contact the presenters. Tapes are
At this point, I'm not aware of any text book in the field which defines
hyperacusis or provides a clinical description or test battery. A
medline search 6 months ago was not very productive. Medical doctors -
especially neurologists seem to use the term loosely and inaccurately.
Check Dorland's Medical Dictionary. There are better terms.
I would suggest no diagnositic work up is complete without OAE's these
days. Might also run the SCAN and a MLD.
