Abstract
A body type hearing aid was modified to provide sensitivity and localization for the affected ear in unilateral hearing loss. This was a standard, moderate gain, body-type hearing aid positioned on the upper left or right quadrant of the chest near the shoulder. The external receiver and a specially vented, custom-fitted earmold was positioned in the normal ear. The venting of the earmold permitted transmission of natural, unamplified sound from the environment as well as amplified sound. This variation was used on 13 children between the ages of 7 and 13 having unilateral sensori -neural or mixed type hearing losses. Success was reported in all but 1 case.
