Overview
Brief Summary
This study will assess the benefit of extended wear hearing aids for subjective listening effort, compared to the unaided condition, in adults with mild sensorineural hearing loss.
Detailed Description
This study will assess the benefit of extended wear hearing aids for subjective listening effort, compared to the unaided condition, in adults with mild sensorineural hearing loss. Participants will be experienced hearing aid users who have previously worn or currently wear extended wear hearing devices. The primary objective will be to assess subjective listening effort, compared to unaided.

- •Good understanding (read/write/speak) of the English language
- •Willingness to comply with all study requirements
Exclusion Criteria

Outcomes
Primary Outcomes
NASA Task Load Index (NASA-TLX)
Time Frame: Day 1 of 1 day study
A raw score on six demensions (mental demand, physical demand, temporal demand, frustration, effort, performance) on a scale from 1 (low/good) to 20 (high/poor). A higher score indicates higher levels of subjective effort.
Secondary Outcomes
- AZBio Speech in noise testing(Day 1 of 1 day study)
