Brief Summary:
This document describes a clinical validation study for a double-blind repeated-measures comparative study of the GN self-fitting method to a validated audiology-best-practices method when fitting the GN Self-fitting Hearing Aid, a device intended for persons aged 18-75 years old who have mild-to-moderate hearing loss. A crossover wear-time field trial will be conducted. The focus of the study is on the validity of the self-fitting process used to select appropriate frequency-gain characteristics for the GN Self-fitting Hearing Aid, and the safety and effectiveness of the device.
