Hearing aid selection by brainstem audiometry.

Hearing aid selection and adjustment by means of brainstem audiometry was tested in 29 hearing impaired children. A projection procedure is introduced which employs normal and pathological intensity-amplitude functions. This method enables determination of some basic properties of appropriate hearing aids, such as average gain, type of compression, compression factor and onset level. Hearing aid evaluation is discussed for two examples of conductive and sensorineural impairment.
