Our mission:

Improve assessment of hearing loss and hearing treatment effects on speech perception and improve speech perception outcomes of individuals with hearing aids and cochlear implants.

Research Areas

Programming Cochlear implants to improve spatial hearing and spectral resolution

Individuals with cochlear implants struggle to understand speech in noise, such as multiple talkers. Cues of the talker location individual voice characteristics can be used to attend to and better understand speech. This study examines methods to program cochlear implants to better use these location and voice cues for speech understanding.

Real-world hearing aid and cochlear implant speech understanding benefits

Clinical tests of speech understanding are in quiet or simple noise from one location. In contrast, patients experience complex noisy backgrounds with 360 degrees of sound. This study focuses on testing the benefits of hearing aids and cochlear implants in complex acoustic environments that patients experience in their daily lives.

Hearing aid and direct-to-consumer hearing device comparisons for speech understanding and sound quality

Evermore direct-to-consumer devices are available for patients to purchase online or in stores. But will they really improve speech understanding and how do they sound? This study compares speech understanding and sound quality across traditional clinician-fit hearing aids and direct-to-consumer hearing devices.
