Evaluating Hearing Aid Noise Reduction for Cochlear Hearing Loss
This study is testing different settings of a deep neural network (DNN) noise-reduction technology in hearing aids. We want to see how well these settings help people with mild-to-moderate cochlear hearing loss understand speech in noisy places. You would try three settings: no noise reduction, a low-strength setting, and a high-strength setting. Researchers will compare how well you recall speech in different noise levels. The goal is to find which noise reduction strategies work best to improve speech clarity. This study is currently unclear on its recruitment status and plans to enroll 50 participants.
- Study design
- This interventional study plans to enroll 50 participants. It compares three different hearing aid noise reduction settings (Off, Low, High) and two noise levels (Negative SNR, Zero signal-to-noise ratio).
- What's involved
- You would participate in a single study visit, lasting approximately 1-2 hours. During this visit, you will listen to speech and recall what you heard immediately after each presentation.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your speech recall will be measured immediately following presentation of each dual-sentence trial during the single study visit.

What this trial measures
- Immediate Speech RecallDuring a single study visit (approximately 1-2 hours), assessed immediately following presentation of each dual-sentence trial.
Accuracy of immediate verbal repetition of the first sentence in each dual-sentence trial. Participants hear Sentence A followed by Sentence B; they immediately repeat Sentence A aloud. Performance is scored as the number of keywords correctly recalled per sentence. This measure assesses speech intelligibility under different noise-reduction processing conditions and signal-to-noise ratios.
- Delayed Speech Recall (Cognitive Demand)During a single study visit (approximately 1-2 hours), assessed immediately following presentation of each dual-sentence trial.
Accuracy of delayed recall of the second sentence in each dual-sentence trial. Participants hear Sentence A followed by Sentence B, repeat the first sentence immediately, and then type the second sentence from memory. Performance is scored as the number of keywords correctly recalled per sentence. This measure reflects the combined effects of speech intelligibility, working-memory load, and cognitive demand under each noise-reduction processing condition and signal-to-noise ratio.
