Brief Summary:

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

Arm Intervention/treatment
Experimental: Experiences Hearing Aid user
Single arm study, all participants in this arm. Participants will be experienced hearing aid users.
Device: Remote Microphone
Experienced hearing aid users will be trained on and use a remote microphone for 30 days. Pre- and Post- measures will be taken to determine benefit. Participant characteristics will also be assessed (such as self-efficacy) to explore personality factors that may contribute to benefit from devices.
Other Name: Roger Select

Primary Outcome Measures :
  1. Change in Abbreviated Profile of Hearing Aid Benefit (APHAB) [ Time Frame: Change from baseline to final appointment will be assessed. Participants will take a baseline at the start of the trial and then complete post-intervention at the end of the 30-day trial. ]
    Self assessment, disability based inventory that is used to document outcomes of hearing aid fittings. The APHAB uses a percentile scale (Percent of Problems). This measure has 4 subscales: Ease of communication (EC), Reverberation (RV), Background Noise (BN), and Aversiveness (AV). A lower score indicates a better outcome. We will look at both the global change (defined as EC, RV, and BN scores improving by at least 5 points each) and individual subscales (For EC, RV, or BN a change in 22 points is considered significant and for AV a change of 31 points is needed to be considered significant).

Secondary Outcome Measures :
  1. Change in Speech, Spatial, and Qualities of Hearing (SSQ) [ Time Frame: Change from baseline to final appointment will be assessed. Participants will take a baseline at the start of the trial and then complete post-intervention at the end of the 30-day trial. ]
    Questionnaire, clinical patient interview design where participants respond on a scale of 0 to 10, with 10 indicating perfect hearing ability and 0 indicating complete inability.There are 3 subscales calculated by averaged the responses to the questions for each subscale. A change of 2 points is considered a moderate effect with increase in score indicating improvement.
