Details and patient eligibility

About

Listeners will conduct sound quality ratings of recordings talkers in a moving car processed using three different microphone processing strategies: an investigational adaptive directional microphone, an omnidirectional microphone and a fixed directional microphone. Participants will listen to the recordings streamed via commercially-available and individually-prescribed hearing aids, and conduct ratings onsite in the lab. The procedure will involve a training session and within-subject repeated measures. Stimuli will be randomized.
