M100 Interhemispheric Latency Differences Restored with Amplification of Asymmetric Hearing Loss

Department

Audiology

Abstract

In asymmetric hearing, large differences in thresholds between the two ears result in more synchronous timing of interhemispheric activation, which may have a detrimental effect on complex listening tasks (Pross, et al., 2015). In this study, magnetoencephalographic imaging (MEGI) was obtained prior to fitting three participants with Lyric hearing aids, and at 3, 6 and 12 months following fitting. Behavioral assessments were also completed. Following amplification, MEGI interhemispheric latency differences increased and unaided speech-in-noise improved.
