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
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Customized to match listening strategy First | Active Comparator | Participants in this arm will listen to hearing aid settings programmed to match their listening strategy first, then the general setting |
|
| Not customized to match listening strategy First | Active Comparator | Participants will listen to hearing aid settings based only on their pure-tone thresholds first (general hearing aid settings), then ones programmed to match their listening strategies. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Hearing aid with settings customized to match their individual listening strategy | Device | Behind-the-ear hearing aids that have been programmed based on the participant's individual listening strategy and hearing loss. |
| Measure | Description | Time Frame |
|---|---|---|
| Speech recognition | Participants listen to and repeat sentences, they are scored based on the % correct of keywords they accurately repeat. | Outcome measure is collected during the intervention, a two hour visit to the lab where they are wearing the hearing aids |
| Measure | Description | Time Frame |
|---|---|---|
| Speech Spatial Quality | Rate perceived intelligibility and quality on a scale of 0 to 10 with 10 generally being better | Outcome measure is collected during the intervention, a two hour visit to the lab where they are wearing the hearing aids |
