The definition of hyperacusis that I use and the definition at the Univ. of
Maryland center is UCLs less than 100 dB. This has worked fairly well in
clinical practice. Patients who do not complain of hyperacusis typically
have UCLs at 110 dB or higher while the converse is true of patients with

If this child does have hypercusis by history, behavior, and testing,
hearing protectors are not indicated except for when she is exposed to
intense sounds. For everyday listening, it is better to employ Tinnitus
Retraining Therapy which can consist of either constant exposure to sound
or fitting of Viennatone (available from Starkey) AM/Ti binaural noise
generators. The habituation process will take some time - 6 -12 months).
