In recent years, hearing loss caused by diabetes has gradually attracted attention. Whether it is diabetes-induced hearing loss or noise-induced hearing loss, the audiological features are symmetrical sensorineural hearing loss dominated by high frequencies. The two have certain similar characteristics, but their pathogenesis is different. different. This article reviews the literature on the audiological characteristics, pathogenesis, and mutual overlapping effects of diabetic hearing loss and noise-induced hearing loss, in order to provide ideas for further research
