Noise Exposure and Near-Infrared Light

Completed · Not applicable · Has a placebo group

Conditions studied: Hearing Loss, Noise-Induced

In brief

The primary objective of this work is to determine the effect noise has on the auditory system (both auditory health and performance) and also the degree to which the effect of pre-noise therapy such as Near Infrared (NIR) light can mitigate the effects of noise exposure.
