Investigating the Relationship Between Directional Microphones, Compression, and Working Memory in Realistic Spatial Conditions.

Northwestern University·interventional·Posted Aug 20, 2020·Updated Sep 15, 2025

In Brief

A clinical study evaluating Hearing aid for Hearing Loss, Sensorineural. Completed, enrolled 42 participants across 1 site.

Detailed Summary

The goal of this project is to determine whether the selection of hearing aid settings should be based in part on an individual's cognitive characteristics (specifically, working memory). We anticipate the outcomes of this study to be applicable to realistic listening conditions.

Interventions

Hearing aiddevice

Settings in a wearable hearing aid will be adjusted within a clinically-relevant range for two features. The features include wide dynamic range compression and microphone directionality.
