简要总结
Internal research on the manufacturer's hearing aid products has idenitfied areas in which the investigators can improve the hearing aid frequency response curve. This study aims to investigate the current freqeuncy response curve in the manufacturer's products to variations of these curves to determine if hearing aid users prefer the variations over the manufacturer's standard curve.
详细描述
Internal testing has identified areas in which the investigators can improve the performance of the manufacturer's hearing aid products. This should potentially lead to increased hearing aid user satisfaction due to an improvement in sound quality. However, the investigators are currently unsure if implementing these new frequency response curves will be preferred by the manufacturer's clients. Therefore, a study is proposed in which hearing aid users will compare the manufacturer's current frequency response curve to variations made to the curve and determine which one they prefer while listening to live speech/music or while streaming speech/music.

结局指标
主要结局
Streaming Sound Quality Ratings
时间窗: 60 minutes
Pre-filtered sound samples (based on frequency response curves) will be presented via a paired comparison task in which participants will determine which sound sample they prefer (i.e. better sound quality). Sound samples will be presented via hearing aids that are programmed to the participant's hearing loss. Participant's will be presented with two samples at a time and will choose which sample they prefer. For example, if Sample A was preferred over Sample B, then Sample A gets a score of 1. If Sample B was preferred over Sample A, then Sample B gets a score of 1. At the end of the task, scores will be tallied to determine which sample was preferred the most overall. There will be 5 different samples. The minimum value for the tallied score would be 0 (the sample was not preferred at all) and the maximum value would be 8 (implying that the sample was preferred in all trials). Higher scores mean that the sample was preferred more and lowers scores mean the sample was not preferred.
