Speech Locator In-car Performance Evaluation

Sonova AG·interventional·Posted Sep 23, 2021·Updated Aug 17, 2025

In Brief

A clinical study evaluating Investigational adaptive directional microphone strategy, Comparator omnidirectional microphone strategy, and 1 other intervention for Hearing Loss. Completed, enrolled 20 participants across 1 site.

Detailed Summary

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.

Interventions

Investigational adaptive directional microphone strategydevice

A receiver-in-canal hearing aid developed by the Study Sponsor used with the investigational adaptive directional microphone strategy that is expected to improve sound quality of speech in a car.

Comparator omnidirectional microphone strategydevice

A receiver-in-canal hearing aid developed by the Study Sponsor used with the comparator omnidirectional microphone strategy that is used with the default settings as specified in the manufacturer's fitting software.

Comparator fixed directional microphone strategydevice

A receiver-in-canal hearing aid developed by the Study Sponsor used with the comparator fixed directional microphone strategy that is used with the default settings as specified in the manufacturer's fitting software.
