Abstract
Aided threshold improvement obtained by 12 hearing-impaired children was compared to the acoustic gain of their hearing aids using both the traditional 2-cc coupler and a variable volume coupler designed to approximate real ear volume in children. Results indicated that acoustic gain determined in the 2-cc coupler underestimated aided threshold improvement by approximately 8.7 dB. Use of the variable volume coupler to determine acoustic gain, however, adequately predicted aided improvement at comfort setting. Use of the variable volume coupler in hearing-aid fittings for children is discussed with special emphasis on preventing over-amplification.
