Study Summary
This study will evaluate the impact of hearing aid microphone directionality technologies and settings on speech understanding in noise for experienced hearing aid users. It will also evaluate the participant's spatial awareness of sounds using these different hearing aid microphone directionality technologies.
Primary Outcome
Participant describes an acoustically noisy environment in which recorded speech is played from a speaker directly in front of the participant and recorded multi-talker babble is played from multiple speakers around the participant. The participant uses a slider tool to choose if scene sounds acoustically wide (hearing all noise and speech), or acoustically narrow (hearing more of the speech than the noise). The range of the slider is 0-100, with 0 indicating the sound scene is "wide" and 100 in
Interventions
- DEVICE Phonak Audeo hearing aid
- DEVICE Phonak hearing aid with multiple directionality settings, adjustable via a mobile app
