Investigating Hearing Aid Frequency Response Curves

Sonova AG·interventional·Posted Aug 30, 2022·Updated Mar 24, 2025

In Brief

A clinical study evaluating Hearing Aid - Standard Curve, Hearing Aid - Variation #1, and 3 other interventions for Hearing Loss, Sensorineural and Hearing Loss, Bilateral. Completed, enrolled 33 participants across 1 site.

Detailed 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. 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.
