john roach on 03 Jan 17"The ear has 20,000-30,000 hair cells, the nerve endings responsible for carrying the electrical impulses through the auditory nerve to the brain. These delicate receptors bend or flatten as sounds enter the ear, typically springing back to normal in a few hours, or overnight. But over time, loud sounds can cause more permanent damage as hair cells lose their resilience. Frequent and intense exposure to noise will cause these receptors to flatten down, stiffen, and eventually break. The damage can interfere with the ability to determine the location of a sound, cause extreme sensitivity and pain, and make it impossible to discern language with background noise. One in 20 Americans, or 48 million people, report some degree of hearing impairment. RELATED STORY What My Hearing Aid Taught Me About the Future of Wearables "
