Development of test procedures for evaluation of binaural hearing aids. A final report.

Research in the rehabilitative aspects of audiology has not been as extensive as audiological research focused on the development and use of various auditory tests for diagnostic purposes . The work described here, supported by the Veterans Administration, represents an effort to restore the balance by focusing on the communicative problems experienced by hearing-impaired veterans and others, and their rehabilitative needs. Specifically, the overall goals of these investigations have been the development of test procedures for assessing the efficiency of binaural hearing aids, and the development of methods for increasing the efficiency of hearing aid use . This report will consist of two parts : a summary of the work completed under earlier contracts, and of the projects supported by Veterans Administration Contract No . V101 (134) P-6. Greater emphasis will be placed on the reporting of the latter projects.
