A New Way to Prevent Noise-Induced Hearing Loss

Washington University School of Medicine and the University of Iowa may have discovered a new way to prevent noise-induced hearing loss.

In this study, researchers tested a drug compound on mice before exposing them to 100 dB SPL for 2 hours. By utilizing a drug that targets a selective blockade of Calcium permeable AMPA receptors, they found that the mice were protected against noise-induced synaptopathy. This study could impact the way we prevent hearing loss through noise exposure.
