Brief summary
The goal of this clinical trial is to learn if hearing aid settings that are customized to individual listening strategies result in better speech understanding than non-customized hearing aid settings. The main question it aims to answer is: Do customized hearing aid settings result in better speech understanding? Researchers will compare hearing aid settings that match individual listening strategy to a general setting. Participants will: Wear hearing aids for a 2-hour visit to our laboratory. Listen to some sentences in noise and repeat the sentences they hear, with two different hearing aid settings Listen to some sentences in noise and rate how understandable they think those sentences are, with two different hearing aid settings
Detailed description
Participants will complete standard clinical hearing evaluations and a listening profile test to evaluate their individual listening strategy. Hearing aids will then be programmed either based on their clinical hearing evaluations alone using typical hearing aid settings or based on their hearing test with settings further adjusted to account for their individual listening strategies.
Interventions
DEVICEHearing aid with settings customized to match their individual listening strategy
Behind-the-ear hearing aids that have been programmed based on the participant's individual listening strategy and hearing loss.
DEVICEHearing Aid with settings based on audiogram alone
Behind-the-ear hearing aids that have been programmed based on their hearing loss and typical clinical settings.

Masking description
Participants will not know when they are listening to a hearing aid that is programmed with general or customizable settings.
Intervention model description
Participants will listen to hearing aids programmed specifically for their listening strategies or to ones programmed with typical clinical settings first, then switch strategies.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Speech recognition | Outcome measure is collected during the intervention, a two hour visit to the lab where they are wearing the hearing aids | Participants listen to and repeat sentences, they are scored based on the % correct of keywords they accurately repeat. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Speech Spatial Quality | Outcome measure is collected during the intervention, a two hour visit to the lab where they are wearing the hearing aids | Rate perceived intelligibility and quality on a scale of 0 to 10 with 10 generally being better |
