Step on the streets of New York or any other major city and you will be hit by a noise. It may come from a car horn, alarm, barking dog, jackhammer, or any other source. But no matter what you hear, you can’t escape it. If you live in this city, even in your apartment, you might be surrounded by a noisy neighbor or a music in the restaurant where you live.
So far, we have come to realize that this situation is very, very bad for our health. Epidemiological studies have shown that noise make it impossible for us to get a good night’s sleep, increased the risk of heart disease, high blood pressure and the risk of dementia, adds to our stress hormones, associated with the child’s memory and reading comprehension questions, and cause hearing problems.
But we still tend to see quiet as a luxury. “People just have this general attitude that noise is just a nuisance… Even people affected by the noise will adopt this attitude, “said Harvard University exposure scientist Erica Walker, who studies how people are affected by noise. “This is the sacrifice we have to make, because we choose to live in these places that are close to everything, and this is something that we can bear, and that is a time that we can get used to.”
But it doesn’t have to be that way. Walker and other researchers are investigating how cities reduce volume. First, we must understand the scope of our noise problem. This means creating maps to understand how noise is fluctuating in the city, determining when noise will occur, and determining which Spaces provide much-needed breathing space for urban residents.
“It’s not a problem we can’t overcome, but we have to define it more intelligently, and how we’re going to mitigate it,” Walker said.
Describe the hustle and bustle
For the first time, walker realized how harmful urban noise could be when she entered an apartment in Boston, because the family’s children were so busy. “Above me are the children who have been running all day long; “It’s just incredibly annoying and destructive,” she said. Frustrated, she began to read the effects of constant noise. “I found it much more convenient than I had to deal with my noisy neighbors upstairs.”
Walker decided to investigate what makes city noises so harmful. She measured noise levels in the greater Boston area and surveyed residents to create a cityscape map. She found that noise regulations were rarely enforced, and the world health organization recommends that noise levels remain below 55 decibels during the day and 40 decibels at night in the real world. “I’ve never seen a sound level like this when I measured city sounds,” walker said. “It always ends.”
She also found that loudness was only part of the picture. “The noise is very complicated. But the way we describe it, the way we manage it is very superficial, “she said.
Other characteristics of noise can also affect our long-term health and emotional well-being. These include the frequency of sound, duration of duration, uncertainty and how people feel about it. Walker said: “I’ve asked people what they think is the most annoying noise, people like to say this, ‘if I tell others, no one would have to do anything that I can’t control,” walker said. “It’s just a matter of being incarcerated, and it’s multi-faceted.”
Another pattern Walker notes is that poorer communities tend to be louder and have more low-frequency sounds than others. When walker talk with east Boston residents near the airport and the seat of the two main highway – people report that they not only are they heard the noise, and they felt the noise.
