Primary outcomePrimary: Subjective Description of DIR1, DIR2, and DIR3 in Controlled Soft Noise Environment — 40.31; 55.94; 66.88 units on a scale — p=0.004
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.
