Summary

Mild to moderate hearing loss remains undertreated, largely because of the high cost of hearing aids. A promising and much less expensive alternative is the use of personal sound amplification products (PSAPs), which are electronic, portable, over-the-counter devices that amplify sound. Studies have shown that the use of PSAPs provides significant hearing benefits and improves the quality of life for older adults with mild to moderate hearing loss. However, there is insufficient data to determine the impact of PSAPs use on speech processing in the brain.

The purpose of this study is to use electroencephalography (EEG) measurements to assess the neurobiological and behavioral effects of PSAPs on speech perception in noise in individuals with mild to moderate hearing loss.

The investigators expect that the PSAPs use will result in an immediate improvement in the ability to perceive speech-in-noise, supporting that these hearing devices may be a means of restoring communication skills in people with mild to moderate hearing loss. Behavioral benefits will be associated with increased brain activity in auditory regions and connectivity between auditory and speech regions in the brain.
