The loudness of sound is measured in units called decibels. For example, the humming of a refrigerator is 40 decibels, normal conversation is approximately 60 decibels, and city traffic noise can be 85 decibels.

Sources of noise that can cause NIHL include motorcycles, firecrackers, and small firearms, all emitting sounds from 120 to 150 decibels. Long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The louder the sound, the shorter the time period before NIHL can occur. Sounds of less than 75 decibels, even after long exposure, are unlikely to cause hearing loss.

DATA FROM RESEARCH LABS IN THE STATES.

Negative Effects of Noise Pollution

Many studies have been conducted to study the effects of noise pollution on health and wellness, and the results have shown that noise pollution can negatively impact you in the following ways:

Productivity:

We all know that noise can be distracting, and research proves this. One study examined children exposed to airport noise and found that their reading ability and long-term memory was impaired. Those working in noisy office environments have also been found to be less cognitively motivated, and to have higher stress levels, according to a Cornell University study.

Health:

 Perhaps the most serious problem created by sound pollution is the impact it has on our health. Because sound pollution can trigger the body’s stress response, one of its major health effects is chronic stress and the high levels of stress hormones that go with it. As a result, noise pollution has also been linked with health problems such as heart disease, high blood pressure, and stroke.

It’s also been linked with musculoskeletal problems, as a Cornell University study on office noise found that those working in noisy office environments can also be less likely to ergonomically adjust their workstations for comfort, which can contribute to physical problems. Noise pollution can also impact sleep quality by preventing sleep and disrupting sleep cycles. And, perhaps most significantly, because chronic stress can lower your immunity to all disease, noise pollution is a general threat to health and wellness.

Worse....there is no cure for hearing loss.
