Summary
Internal research on the manufacturer's hearing aid products has idenitfied areas in which the investigators can improve the hearing aid frequency response curve. Based on the conclusions of the first study, we have identified areas that require further analysis and testing prior to implementing of the proposed frequency response curve into our products. 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.
Detailed description
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 and listener comfort. 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 and while in different listening enviroments.
