Trying a deep-learning noise-reduction feature for hearing aids

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Participants with mild-to-moderate cochlear hearing loss will listen to speech stimuli presented with various levels of background noise while wearing a hearing-aid configuration that isolates single-microphone noise-reduction. The study compares several processing modes (no noise reduction, low, and high DNN-based noise reduction) across multiple signal-to-noise ratios to represent easier and harder listening conditions. All participants experience every condition in a counterbalanced order to limit order effects, and speech intelligibility is measured under each setting. The monaural, omnidirectional setup removes directional microphone benefits so the effects of the noise-reduction algorithms can be isolated.
