Summary

This study tests an open-source speech-processing platform, called the Master Hearing Aid, as a wearable hearing aid for people with sensorineural hearing loss. Participants will wear the device in real-world settings and adjust it to their liking, then complete speech perception tests and interviews about its performance and acceptability. The goal is to see if this customizable, research-focused platform can be a practical hearing aid option.
