Decibel scale hearing damage4/13/2024 ![]() ![]() And if you can’t avoid loud sounds, try to move away from them.An Introduction to Decibels and Hearing Damage Keep hearing protectors with you, just in case the sound is louder than you expected. Protect your hearing by consistently and correctly wearing ear protection, such as earmuffs or earplugs, if you anticipate being exposed to loud noises. The Sound Level Meter smartphone app developed by the CDC’s National Institute for Occupational Safety and Health (NIOSH) is one example of a decibel meter app that helps workers evaluate sound risks in their environments so they can develop strategies to prevent hearing damage. Sirens from emergency vehicles: 110 to 129 dBAĭecibel meters are one way to measure potential hazards to your hearing health.Here are some decibel ratings for common sounds: Long or repeated exposure to sounds at or above 85 dBA can cause hearing loss. Sounds at or below 70 A-weighted decibels (dBA) are generally safe. Sound is measured in units called decibels. In general, the louder the sound, the faster NIHL can develop. Also, listening to music or other sounds at high volume through headphones or earbuds is hazardous. If you find yourself in a setting where you are shouting to be heard over noise in the environment, chances are that your hearing, if unprotected, is at risk. Helping children practice healthy hearing habits is a major focus of the campaign. ![]() ![]() ® is the NIDCD’s public education campaign to increase awareness among parents of preteens about the causes and prevention of NIHL. adults who report having good to excellent hearing already have hearing damage in one or both ears.Ĭhildren are also at risk for NIHL. adults ages 20 to 69 have NIHL, and a quarter of U.S. Centers for Disease Control and Prevention (CDC), about 40 million U.S. During National Protect Your Hearing Month in October-and throughout the year-the National Institute on Deafness and Other Communication Disorders (NIDCD) offers science-based resources to help you maintain your hearing health.Īnyone can develop NIHL at any age. Noise-induced hearing loss and tinnitus are preventable. Tinnitus may be constant, occur occasionally, or subside completely after exposure to loud noise. Loud noise exposure can also cause tinnitus-a ringing, buzzing, or roaring in the ears or head. This damage, called noise-induced hearing loss (NIHL), can be immediate-from exposure to an extremely loud burst of sound, for example-or gradual, with sounds seeming muffled or conversations becoming more difficult to understand. Loud sounds in the environment can permanently damage or destroy the tiny and fragile hair cells within the cochlea-the small, snail-shaped organ for hearing in your inner ear-and diminish your ability to hear a range of sounds.
