Noise-induced hearing loss: perspectives Rodney C. Diaz
In this year’s Auditory and Vestibular Science Section of Current Opinion in Otolaryngology – Head and Neck Surgery, we review new laboratory and animal models of noise-induced hearing loss as well as consider noise-induced hearing loss from three clinical perspectives: the occupational perspective, the military perspective, and the recreational perspective. In our first review, Dr Daniel Eberl presents two unique and unexpected new animal models for hair cell modeling: the hair cell bundle of the sea anemone and the Johnston’s organ of the fruit fly. These unorthodox animal models present unique opportunities beyond the classic mammalian and avian animal models in the study of hair cell damage in the context of noise and acoustic trauma. As is well known, it does not matter what the source of sound is, whether from a factory or explosion or personal listening device, if the total energy – imparted by the absolute pressure or intensity and the overall duration or time exposure – of sound is equivalent, then the source is irrelevant. However, each of the three clinical perspectives provides a unique backdrop to our consideration
of noise-induced hearing loss, and what we as health care providers can do to prevent or mitigate it. Dr Travis Pfannenstiel will discuss the unique sound exposure risks inherent in military service and military combat that are not present in other arenas. As Dr Robert Hong explains in his perspective, occupational noise exposure, whereas being probably the most prolific stage for noise-induced hearing loss from an epidemiological standpoint, is also the most tightly regulated and therefore the easiest setting in which to effect beneficial and global change that can help preserve hearing health. Drs Robert Ivory and Rebecca Kane discuss the unique challenges to counseling and managing patients who are at risk of noise-induced hearing loss through completely elective, and sometimes intentional, high noise risk endeavors. Acknowledgements None. Conflicts of interest The author declares no conflicts of interest.
