Noise pollution causes hearing loss and affects health
A screaming child, TV blaring in the living room, a vacuum cleaner, loud music coming from your teen's bedroom: a busy home can be a source of constant noise. Once you step outside, there's even more noise pollution. On an average day, you may hear your neighbor's lawn mower, honking cars, sirens, maybe even ear-shattering sounds of a construction or a work site - a saw, a drill, a jackhammer.
Welcome to the modern – and very noisy – world. Unless you live in a very quiet rural area, you are no stranger to the phenomenon of environmental noise, commonly called noise pollution.
Noise pollution is often referred to as the "modern unseen plague" for good reason. It may be unseen but certainly not unheard! It disturbs us practically everywhere we go, day and night. And, besides leading to hearing loss, it impacts our physical and mental health in more ways than one.
A clear and present danger
World Health Organization (WHO) is just one of many groups that sounds an alarm about the dangers of noise pollution. "Excessive noise," the WHO warns on its website, "seriously harms human health and interferes with people's daily activities at school, at work, at home and during leisure time."
How big of a problem is this? According to the American Speech-Language-Hearing Association (ASHA), an estimated 30 million Americans are exposed to dangerous noise levels on a regular basis, an increase of 10 million from just a few years ago. And, of course, many millions more are impacted by noise pollution worldwide, so it is fair to say that environmental noise is a growing global problem.
And "problem" is the right word to describe these health and hearing effects of noise pollution:
Causes of noise pollution
Here's another alarming statistic: According to the U.S. Census Bureau, Americans cite noise as the biggest problem affecting their neighborhoods – even more than crime.
What noises do people find most disturbing to their sense of hearing and overall well-being? A survey conducted several years ago among residents of Curitiba, a Brazilian city with the population of 1.6 million, showed that traffic was the number one culprit (73 percent), followed by noisy neighbors (38 percent).
It is not surprising that survey participants were most impacted by loud traffic since most urban sounds far exceed the 80 dB threshold. For example, a garbage truck registers at 100 dB, a car horn at 110 dB, and an ambulance siren at 120.
Overall, neighborhood noise was cited as the most disturbing type of noise, as all of the study participants indicated at least one of the items belonging to this category: neighbors, animals, sirens, construction, night clubs, toys and domestic electric appliances.
How did this entire ruckus affect the respondents? Irritability was the primary result of exposure to noise, followed by difficulty to concentrate (42 percent), sleeping disorders (20 percent) and headaches (20 percent).
These findings can be applied to any industrialized nation, including the United States. So the question is, what can you do to reduce noise pollution and protect your well-being?
Reducing noise pollution
There is a small but growing awareness of noise pollution and its effects on your health and hearing. Some organizations are dedicated to increasing the safety and silence in our noisy world. For example, Silencity is a New York City-based organization that raises awareness about noise pollution and seeks out restaurants and public spaces where city dwellers can enjoy a quiet, safe respite from the noise. UK-based Pipedown is dedicated to eliminating the annoying canned music we cannot escape when we dine and shop.
These are certainly laudable moves, and more tangible measures like them are needed in all the noisy urban centers. In the meantime, there are steps you can take to protect your hearing and health in general against harmful noise pollution. Better Hearing Institute advises these guidelines:
