Outcomes
Primary Outcome Measures
Sound quality rating
The sound quality ratings will be conducted via a computer-based questionnaire that contains sound samples that participants listen to and rate. Sound quality rating scales are continuous and range from 0 (worst) to 100 (best) with 5 descriptors unique to the dimension at 5 intervals on the scale (0, 25, 50, 75, 100)
Dimensions rated are:
Speech clarity: Very unclear, Unclear, Slightly clear, Clear, Very clear
Noise annoyance: Extremely annoying, Very annoying, Moderately annoying, Slightly annoying, Not at all annoying
Spatialization: I don't know where the talker is, the talker might be [at location], The talker is probably [at location], The talker is [at location], The talker is definitely [at location]
Overall impression: Bad, Poor, Fair, Good, Excellet
Transition annoyance: Extremely annoying, Very annoying, Moderately annoying, Slightly annoying, Not at all annoying

5. Study Description
Brief 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.
