Quick Reference

Devices to protect the organs of hearing, i.e., eardrums, auditory ossicles, and cochlea from loud noise, e.g., due to machinery, gunfire. The simplest ear protectors consist of ear plugs that fit in the external auditory canals. Larger devices resembling headphones fit over the head and effectively insulate against very loud noise, e.g., from nearby jet aircraft engines.
