Hearing-impaired individuals are shown to benefit from Sonic Touch products in many different environments. In this study, APHAB benefit was measured for 15 hearing impaired volunteers at The Center for Amplification and Hearing Research in Salt Lake City, Utah. Volunteers were fit binaurally and the questionnaire was administered after four weeks of wear time.

In this test, a lower Aided score is better. A Difference of 22% or more is considered a significant improvement.
