Details and patient eligibility

About

The stimuli consist of speech in quiet, speech in noise, reverberant speech, and music recorded with different hearing aid settings, post-processed for headphone presentation and incorporated in an online sound survey. Participants will receive tablets and headphones to conduct a sound quality rating at home. The survey will involve a training session and within-subject repeated measures. Stimuli presentation will be randomized by sound quality rating tool.
