Abstract

Considerable differences of opinion still exist concerning the validity, reliability, and value of performance comparisons of hearing aids in clinical hearing aid evaluations or selections. A number of research audiologists contend that no real differences in aids can be demonstrated, while many clinically oriented audiologists show results from their experience of differences of considerable magnitude. An analysis of 298 hearing aid evaluations in our clinical laboratory using peak performance, current aids preselected as suitable for each patient, showed that large differences between the poorest and best performing aids occurred frequently. In our series, 47% of the patients showed differences of 20% or more in speech discrimination between aids and 86% showed differences of 10% or more.
