If you’re exposed to loud or prolonged noise at work, your employer should provide hearing protection. Even a high-energy exercise class where the music is turned up to the max could enter the noise-level danger zone, Reed says-in that case, try asking the class instructor to turn the music down, or wear earplugs.Ĭheck your workplace.

That includes concerts and sporting events-where, Reed points out, fans are often encouraged to be as loud as possible-but also movie theaters and fireworks displays. Wear hearing protection, such as earmuffs or earplugs, when you know you might be exposed to loud sounds (and put these on kids, too).
While you may not be able to move away from a noisy neighborhood or work in a quieter environment, consider these steps: (The car horn won’t last that long, but a football game certainly will.) According to NIOSH, exposure to noise levels of 85 decibels (dBA) for more than 8 hours in a day may affect hearing-and the louder the noise, the less time it takes to cause harm.įor instance, a noise level of 100 dBA, similar to that of a car horn from a few feet away or a sporting event, can cause harm after just 15 minutes, according to NIOSH. It’s important to limit your exposure to loud noise, both to protect your hearing and to guard against other possible health effects of noise. Scientists think noise could cause stress in children, just as it does in adults. After all, who doesn’t find it hard to concentrate on a book if someone is vacuuming in the next room?īut there may be issues other than distraction at play, Reed says. This connection makes sense, notes Nicholas Reed, Au.D., an assistant professor in the department of otolaryngology–head and neck surgery at the Johns Hopkins School of Medicine. More recently, a 2018 World Health Organization analysis of 34 studies linked noise exposure to poorer reading comprehension, standardized test scores, and long-term memory. The scientists found that children who lived on lower, noisier floors closer to the highway scored worse on reading tests than those who lived on higher, quieter floors. In one classic study conducted in 1978 (PDF), researchers evaluated children living in a middle-income housing project constructed over a busy highway in New York City. A number of studies have found a link between increased noise exposure and poorer cognitive abilities among children. Other studies have found that higher music volume may lead to more alcohol consumption in bars and restaurants.Ĭhildren may be particularly vulnerable to loud noise. In one 2018 study published in the Journal of the Academy of Marketing Science, scientists found that people in restaurants and supermarkets purchased healthier foods when music and noise were low, and chose unhealthy foods when the volume was turned up louder. And insufficient sleep has been linked with obesity, diabetes, and heart disease, among other health issues.įinally, spending time in noisy environments could lead you to make poor food and drink choices. Noise in your environment may also get in the way of needed rest. “The prevailing thought is if you’re living in a noisy community, noise, of course, disrupts sleep,” according to Richard Neitzel, Ph.D., associate professor of environmental health sciences at the University of Michigan.
In a 2018 study published in the International Journal of Cardiology, for example, German researchers found that people who reported being annoyed by sounds such as the rumble of car and construction vehicle engines and horns in their neighborhood had a higher risk of atrial fibrillation-an irregular heartbeat that can lead to blood clots and stroke. The irritating effect of loud noise in your community may also affect health. “The body responds to stress in a variety of ways, including increasing heart rate, increasing blood pressure,” she says. The researchers concluded that as many as 14 percent of cases of hypertension and 9 percent of cases of high cholesterol were potentially a result of noise exposure-possibly due to the stress of a loud working environment. For instance, one CDC study she co-wrote, published in The American Journal of Industrial Medicine in 2018, found higher rates of hypertension and high cholesterol in people who were regularly exposed to loud noises at work-meaning that for 4 or more hours a day, several days a week, they needed to raise their voice or shout to be heard by someone standing a few feet away. Regular exposure to loud noise has been associated with cardiovascular problems such as high blood pressure in a number of studies, according to Liz Masterson, Ph.D., an epidemiologist with the Centers for Disease Control and Prevention’s National Institute for Occupational Safety and Health (NIOSH).
