Protective Effect of Yang Mi Ryung® Extract on Noise-Induced Hearing Loss in Mice

<div><i>Inhibition by YMRE of noise-induced hearing loss in mice</i>. Hearing impairment was determined by ABR thresholds in the mice of control group, noise group, YMRE group, and YMRE + noise group. ABR thresholds were determined at 4, 8, 16, and 32 kHz in all four groups. <svg height="15.4299pt" id="M4" style="vertical-align:-3.8339pt" version="1.1" viewbox="-0.0498162 -11.596 61.908 15.4299"
