Application of ABRs to the hearing-aid selection process: preliminary data
Journal of Speech and Hearing Research
|March 1, 1986
Summary
Preliminary data suggest auditory brainstem response (ABR) can estimate hearing aid high-frequency gain but not low-frequency gain. Technical factors for ABR in hearing aid selection are also discussed.
Area of Science:
- Audiology
- Neuroscience
- Hearing Science
Background:
- Hearing aid selection is crucial for audiological rehabilitation.
- Auditory Brainstem Response (ABR) is a non-invasive electrophysiological measure.
- Accurate gain estimation is vital for effective hearing aid fitting.
Purpose of the Study:
- To evaluate the efficacy of click-evoked Auditory Brainstem Response (ABR) in estimating hearing aid gain.
- To compare ABR-derived gain estimates with traditional measures.
- To identify technical considerations for using ABR in hearing aid selection.
Main Methods:
- Four normal-hearing and four hearing-impaired subjects participated.
- Hearing aids were tested with three different frequency response settings.
- Gain estimation involved analyzing Wave V thresholds, latency-level functions, acoustic reflexes, coupler gain, and functional gain.
Main Results:
- Click-evoked ABR showed potential in estimating high-frequency hearing aid gain.
- ABR did not effectively differentiate varying levels of low-frequency gain.
- Discrepancies between ABR and other gain measures warrant further investigation.
Conclusions:
- Click-evoked ABR may offer a viable method for assessing high-frequency gain in hearing aids.
- Further research is needed to refine ABR techniques for comprehensive gain estimation.
- Technical aspects of ABR application in hearing aid fitting require careful consideration.
