Long or repeated exposure to sounds at or over 85 decibels (think heavy city traffic) can bring on what’s called noise-induced hearing loss. Since most of the consonants we speak in English require high frequency hearing to understand, “this has a significant impact on one’s ability to understand conversations,” Kim adds. “Noise exposure tends to damage the hair cells at the base of the cochlea which results in high frequency hearing loss,” says Kim. Those signals then get transferred to the hearing centers in our brains that allow us to appreciate sound, speech, and music, while minimizing any unnecessary background noise. Ana Kim, an otolaryngologist at ColumbiaDoctors and associate professor of Otolaryngology at Columbia University Medical Center in New York City.Ībout 10,000 tiny hair cells inside our ears are responsible for converting every sound we hear into electrical signals. “Loud noise exposure can damage or destroy hair cells found within our hearing organ,” explains Dr. You know your ears feel funny after being bombarded by noises like the sound of jackhammers right outside your home.

Loud noises have the ability to, quite literally, get under your skin.īesides being a source of annoyance, they can also have a significant impact on your health.Īccording to a new study out of Germany’s Mainz University Medical Center, an increasing amount of noise can actually throw your heart out of rhythm.
