Study Summary
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.
Primary Outcome
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.
