简要总结
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.

结局指标
主要结局
Subjective Preference DIR1, DIR2, and DIR3 in Controlled Soft Noise Environments
时间窗: Third appointment (day 28 of study)
Using a sliding scale, the participant chooses their preference for listening to the sound scene, however this time, 0 indicates "not preferred" and 100 indicates "most preferred". The slider moves in 5 point increments. This is purely subjective and there is no better or worse answer.
Subjective Description of DIR1, DIR2, and DIR3 in Controlled Soft Noise Environment
时间窗: Third appointment (day 28 of study)
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 indicating the sound scene is "narrow". The slider moves in 5 point increments. This is a purely subjective description and there is no better or worse outcome.
