Awards & highlights

Summary

This trial aims to investigate the effectiveness of using a data-driven approach called speech-based audiometry (SBA) to optimize hearing aid gains for blast-exposed Veterans with functional hearing difficulties (FHDs

Who is the study for?
This trial is for blast-exposed Veterans who have trouble hearing in noisy places but have normal hearing tests. They should not already be using a low-gain hearing aid and must be able to complete speech recognition tasks and undergo neuroimaging.
What is being tested?
The study compares two ways of fitting low-gain hearing aids: the usual method based on pure-tone audiograms, and a new data-driven approach using patient responses to speech in noise. It measures how well participants recognize speech with background noise and their brain activity during these tasks.
What are the potential side effects?
Since this trial involves non-invasive procedures like fitting hearing aids and functional neuroimaging, side effects are minimal but may include discomfort from wearing the device or being in an imaging machine.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Speech-based hearing aid fittingExperimental Treatment1 Intervention
Half of the study participants receive a hearing aid with gain settings determined via speech-based audiometry. Other hearing aid features such as noise reduction and directional microphones are disabled. Of this group of subjects, half are assigned to use the hearing aid daily for six weeks, while the remainder are followed for the same six-week period but use their hearing aids only to complete outcomes testing.
Group II: Audiogram-based hearing aid fittingActive Control1 Intervention
Half of the study participants receive a hearing aid with gain settings determined by applying the NAL-NL2 prescriptive formula to the pure-tone audiogram. Other hearing aid features such as noise reduction and directional microphones are disabled. Of this group of subjects, half are assigned to use the hearing aid daily for six weeks, while the remainder are followed for the same six-week period but use their hearing aids only to complete outcomes testing.
