Remote Microphone Candidacy Study

Completed · Not applicable

Conditions studied: Hearing Loss, Sensorineural

In brief

Despite improvements in digital hearing aid technology, many hearing aid users continue to report difficulty understanding speech in challenging listening environments. Remote microphones have been shown to provide benefit in the most common of these challenging listening environments: distant speakers, background noise, and reverberation. Despite demonstrated benefit, there is a low rate of remote microphone use among adult hearing aid users. One reason for low uptake may be an uncertainty among hearing healthcare providers and potential users regarding expected clinically relevant benefit. This clinical trial will attempt the following: 1. To describe the range of remote microphone benefit among adults with mild-to-moderate sensorineural hearing loss 2. To determine specific individual factors beyond the audiogram that are associated with greater benefit from remote microphones
