Loud entertainment venues like nightclubs, bars, and rock concerts ring in anywhere between 105 to 110 decibels, according to the CDC. At 110 decibels, exposure can result in some degree of hearing loss in less than two minutes although sustained, routine, or repeated exposures are the bigger risk. For comparison, a whisper is about 30 decibels, city traffic about 80, a motorcycle about 95, and firecrackers about 145.
(The CDC says that noises above 70 decibels over a prolonged period can start to damage your ears, so it’s best to stay below that level if possible.)
In addition to hearing loss, research shows that prolonged noise exposure in the womb has been associated with low birth weight, high blood pressure, reduced cognitive function, and inability to concentrate in children. It’s important to remember, however, that these are just associations and do not prove cause and effect.
Zappi said the best way for parents to protect their hearing and that of their children, whether in the womb or out, is to be aware of their exposure levels and the tools they can use to minimize damage to their ears.
“If you start to experience any shifts in your hearing, ringing in your ears, or a headache, that is your body’s way of telling you that you may need a listening break,” Zappi said. “Stepping outside for a few minutes and giving your ears a break can go a long way in protecting your hearing.”
