Objective Measurement of Hearing Aid Benefit

NCT04431622 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

No results posted yet for this study

Summary

Hearing loss is a critical health concern in the rapidly aging population, affecting approximately 22 million older individuals in the United States. Yet, only 30% of individuals who would benefit from the use of hearing aids regularly use them. This project aims to improve the benefit of hearing aids for older adults through incorporation of objective neural measures to assess effects of hearing aid algorithms.

Conditions

  • Auditory Perceptual Disorders
  • Age-related Hearing Loss

Interventions

DEVICE

Hearing aid amplification algorithms

The investigators will use stimulus waveforms that have been amplified and recorded for each individual's hearing loss. These waveforms will be created using Desired Sensation Level, Version 5-C hearing aid targets on a continuum of increased signal manipulation. The NIH-funded open hearing aid platform will be used to provide precise control over hearing aid parameters to create waveforms with linear and fast-acting compression amplification. A third set of waveforms will be created using a current clinical hearing aid that uses typical noise reduction and compression parameters. Investigating the effects of hearing aid algorithms in young normal-hearing and older normal-hearing listeners will aid in interpretation of these effects in the older hearing-impaired listeners.
