Noise-Reduction Algorithm for Hearing Loss
What You Need to Know Before You Apply
What is the purpose of this trial?
This study is designed to understand how different hearing-aid noise-reduction technologies affect a listener's ability to hear speech in noisy environments. Participants will listen to speech at several background-noise levels while trying different processing settings. By comparing performance across these conditions, the study aims to identify which types of noise reduction improve speech intelligibility the most. We expect that some noise-reduction strategies will help listeners understand speech better than others, especially in more difficult listening situations.
Are You a Good Fit for This Trial?
This trial is for individuals with hearing loss who want to test how different noise-reduction settings on hearing aids work in noisy environments. There are no specific inclusion or exclusion criteria provided, so it's open to those interested and likely those who use hearing aids.Inclusion Criteria

- Deep Neural Noise-Reduction Algorithm
Trial Overview
The study tests a deep neural noise-reduction algorithm in hearing aids at various signal-to-noise ratios (SNR). Participants will try high, low, and off noise reduction settings while listening to speech against different levels of background noise.
