Brief Summary

This study will compare far-field speech understanding in noise using a hearing aid alone, with using a hearing aid plus a Roger remote microphone. It will also compare the HA+Roger mic to two other manufacturers' hearing aids plus remote mic systems in the same condition.

Outcome Measures

Primary Outcomes (1)

• AZ Bio Sentence Test

  Validated test of speech intelligibility in which participants repeat as many words as they can from a presented list of 20 sentences. Words correct are calculated as a percent correct from the total number of words presented. Higher percentages mean better speech intelligibility.
