Studies have shown a relationship between noise and increased risk of hypertension, heart attack and angina.

Studies have shown a relationship between noise and increased risk of hypertension, heart attack and angina.

Mathias Basner, a scientist dedicated to the study of noise in a lecture on TEDMED talks about how noise affects health and sleep people, reports the online edition of the with reference for a New time.

In our day, silence is a rare pleasure, and the price is our health. Surprisingly high price, as it turned out. Fortunately, we have things to do today — each of us personally and society in General — to better protect your health and enjoy the benefits of silence.

I assume most of you know: the high level of noise leads to hearing loss. Whether you go with a concert or bar, if you experience ringing in the ears, you can be sure that you already have damaged hearing and, most likely, it is irreversible. Hearing loss is no joke. However, the noise is damaging our health in other ways. They are not well known, but just as dangerous as impaired hearing.

So what do we mean when we speak about noise? Noise is defined as unwanted sound, which includes the physical component, that is, the sound as such, and the physiological component — the circumstances that make this undesirable sound. A good example is a rock concert. The spectators who came to the rock concert does not consider the performance of musicians noise even with the volume at 100 decibels. They enjoy the music and even pay a hundred dollars for a ticket, so whatever loud music may be, they do not perceive it as noise.

For comparison, someone living three blocks from the concert hall, trying to read a book but can’t focus because of the music. Although the sound pressure in this situation is much lower, people perceive this music as noise that can provoke a reaction, which over time will adversely affect his health.

So why is it so important to be able to enjoy the silence? Because, in addition to hearing loss, the noise has an impact on human health overall. However, in our time is becoming increasingly difficult to find a quiet place in view of the constantly increasing number of vehicles, urbanization, unfolding construction, air conditioners, machines for harvesting leaves, lawn mowers, outdoor concerts and bars, players and neighbours having parties till three in the morning.

In 2011, the world health organization estimated that each year in Western Europe due to noise pollution lost 1.6 million healthy years of life. One of the results of noise impact is the creation of communication barriers. You have to speak louder to be understood. In the worst case, may even be necessary to interrupt communication. In a noisy environment, the probability that it will be misinterpreted. This is a possible explanation for why the children attending schools in noisy areas, academic achievement lower than their peers, as evidenced by the conducted research.

Another result of the impact of noise on the body is the increased risk of cardiovascular disease in people exposed to certain noise levels over a long period of time. Noise causes stress, especially if we are not able to control it. Our body produces stress hormones such as adrenaline and cortisol, which alters the composition of the blood, as well as the structure of blood vessel walls, which become less elastic in just one night in a noisy room.

Epidemiological studies have shown a relationship between noise and increased risk of hypertension, heart attack and angina. And despite the fact that this risk accumulates in small doses, it poses a great problem for public health because the noise is everywhere, and he affected many of us.

A recent study showed that reducing the noise pollution of the environment by only five decibels, Americans annually would save $3.9 billion, which today are spent on the treatment of cardiovascular diseases. There are other diseases, such as cancer, diabetes and obesity, which are also associated with the influence of noise, but we do not yet have sufficient evidence that the noise is the cause of their development.

Another important consequence of noise pollution is sleep disturbance. Sleep is an active mechanism for the body, it prepares us for the next phase of wakefulness. The silence in the bedroom is the key to what researchers call “hygiene healthy sleep”. And our auditory system is the guard, which carries out constant monitoring of the external environment, identifying potential threats, even when we sleep. Therefore, the noise in the bedroom prevents to fall asleep quickly.

Because of the noise, we can Wake up in the night. It can also prevent the normalization of blood pressure during sleep. There is an assumption that if the result of the noise a person experiences insomnia for several months and even years, the risk of cardiovascular disease increases. However, often we are not aware of the sleep disturbances caused by noise, because during sleep a person is unconscious.

We conducted a study of the impact on sleep traffic noise. Waking up in the morning, many of the subjects told us: “I slept great, once fell asleep and never woke up”. But when we looked at made during sleep recording physiological reactions of subjects, we saw that they woke up and their sleep was very intermittent. These periods of wakefulness was too short so that the subjects were awake and in the morning nothing of them remembered. However, these periods can significantly affect how relaxed people feel after sleep.

So what sounds are considered too loud? The first sign is that you have to change their behaviour. To be understood you have to speak louder. Or you turn on the TV on high volume, avoid being outdoors or close the Windows, moving the bedroom on the ground floor of the house or even installing insulation. A move to less noisy areas but, of course, not everyone can afford it.

What can we do right now to improve our sound environment and protect the health? First, if you think some sounds are too loud, do not be silent about it. Many theatre owners seem to think that in the movie, just go deaf. If you complained about the noise, but there was no response, ask for a refund or leave it. This language, as a rule, administrators know very well.

Also explain to children that noise affects health and what if now they will listen to loud music, then in older age they will have to reap the rewards.

You can also move the bedroom in the quietest place in the house: the noise of street transportation you will protect the walls of your home. Seeking rental or purchase of housing, give preference to locations that are in quiet areas. Visit the place of your future residence at different times of the day, ask neighbours about how noisy things are in this area.

Wear noise-cancelling headphones while travelling or in the office, if your building a high level of background noise. In General, looking for a quiet place, especially at weekends or during the holidays. Let your body relax.

By the way, four years ago, I visited Japan for a conference on the issues of noise pollution. When I returned to the United States, already at the airport I covered the sound wave. This suggests that we have ceased to realize that are constantly subjected to noise pollution and what value we are a quiet space.

What else can you do? There is such a thing as a carbon footprint. By analogy, there is a noise trace. And there are things we can do to make this footprint smaller. For example, it is not necessary to mow the lawn on Saturday at seven in the morning. Your neighbours will say thank you for it. Or use a rake instead of a blower. In General, it is most reasonable to limit the noise at its very source, so when you are going to buy a new car, air conditioning, blender, or something else, give preference to those models that create less noise. Many manufacturers indicate the level of noise generated by their merchandise, and some even advertise it. Take advantage of this information.

Many believe that the solution is to strengthen the regulation and control of noise, considering it obvious. But not so simple as it seems because many of the activities that create noise, are also a source of profit. Take, for example, the airport and everything to do with his work. Thanks to our ongoing research policy, find out what level of noise can adversely affect health, allowing them to develop reasonable measures to reduce noise.

Robert Koch is credited with saying: “someday man will have for its existence as hard to deal with the noise, as he struggles now with cholera and the plague”. I think this moment has come, and I hope that we will win this fight. And when that happens, we quietly celebrate our victory.

Noise nuisance from neighbours, Punggol, Singapore

Singapore: Over the past two years, one Housing Board block in Punggol has seen heavy market activity. Six households on the same floor moved out – all because of one woman.

Dubbed the “neighbour from hell”, she is accused of splashing oil at doors, playing loud music and stomping on the floor.

One neighbour even claimed she had left a bloody pig’s ear on a shoe rack.

Multiple police reports were made. Feeling helpless when told by the authorities that what she did was not an arrestable offence, six families to date have sold their flats, with the latest one moving out last November.

New families who moved in said they have also made reports to the authorities.

The second resident in the Punggol Central HDB block to move out due to the neighbour did so with her husband and two-year-old daughter in February last year, five years after moving into the Build-To-Order block, which has a mix of two-, three-and four-room flats.

She told The Sunday Times that it was “so stressful” that she even appealed to HDB to let her sell her flat before completing the five-year minimum occupation period. Her appeal was rejected.

“I simply couldn’t take it anymore. I would go home after work to find some kind of liquid splashed on my door. One day it was used cooking oil, another day it was porridge. The worst was when I saw a pig’s ear on my shoe rack,” she said.

“It was my first flat and I felt very suay (unlucky). I sold my flat to another family. I felt sorry for them but everyone wants to escape.”

The neighbour in question is a 51-year-old housewife.

In 2013, the divorcee and her son, who is waiting to enter university, moved into their two-room flat.

Interviews with her former and current neighbours indicate that the trouble began the year after.

One neighbour showed a folder of at least 17 police reports filed, as well as complaints to HDB.

A police spokesman said: “As the reports were for non-arrestable offences such as intentional harassment, noise pollution and mischief, the housewife’s neighbours were advised to lodge a magistrate’s complaint. All involved parties were also advised to keep the peace.”

A magistrate’s complaint is filed when one wishes to start a private prosecution against someone he believes has committed a criminal offence against him. The neighbour who filed the complaint, after an earlier attempt at mediation failed, lives in the flat above the woman.

He claims she intimidated him with “a large stone” when she confronted him about noise from his flat last month.

The accusations were disputed by the housewife who said he had provoked her by dropping metal balls on his floor which she could hear.

“So, I took a pebble and went up to bounce it outside his unit’s corridor as I was angry. It disturbed my sleep and it was not the first time. I also called the police,” she said.

Speaking from her home for three hours on Thursday, the housewife was calm and articulate as she addressed her neighbours’ accusations.

“If ex-owners said they sold their flats because of me, I tell you, I am not that great. I, one person, cannot do all this. I have footage of their nuisance acts and they are no bunch of sweet peas,” she said and accused her neighbours of ganging up against her.

One ex-neighbour who wanted to be known only as Lee, said the neighbours had held a few meetings as they experienced the same issues with the housewife.

The disputes started with the previous owner of the unit facing hers, recalled the housewife.

She said the couple threw cigarette ashes into the gap between her wooden door and grille gate. So she installed three closed-circuit television cameras outside her flat.

In the past five years, the woman added, she has filed multiple complaints with different agencies, including the National Environment Agency, about her neighbours.

When told that her neighbours had complained of loud music and banging doors coming from her flat, the housewife said she has to sleep with her radio on each day “to drown out the noise” from upstairs.

“My conscience is clear.”

Last year, the couple opposite the housewife sold their home to a 34-year-old single mother.

On her first day home, she found police at her door.

The administrative assistant who declined to be named said: “She had called the police to complain that my cousin was making noise and smoking at the corridor.

“A month later, she poured cooking oil outside my flat on three occasions.” — The Straits Times/Asia News Network

Guangzhou and Beijing Rank as Two Loudest Cities in the World

China is home to two of the loudest cities in the world – Guangzhou and Beijing

According to a recent article in The Guardian, Guangzhou, China, ranked as having the worst levels of noise pollution in the world, followed by Cairo, Paris, Beijing and Delhi.

New study Global Acoustic Insulation shows demand for acoustic insulation in China totalling $1.5 billion in 2018, making it the second largest national market in the world in value terms behind the US.

Through 2023, demand for acoustic insulation in the Asia/Pacific region is expected to grow 6.3% per annum to $4.3 billion, representing 46% of value growth worldwide. Going forward, gains will be boosted by rising standards of living, supporting increased access to air conditioning, associated HVAC equipment output, and higher quality building stocks the rapid expansion of nonresidential building construction in China
growth in industrial equipment and appliance production government efforts in some countries to improve noise pollution and worker safety regulation.

When we include all regions, Freedonia forecasts demand growth at 4.9% per year to reach $11.4 billion in 2023. Despite the popularity of fibreglass in North America and of mineral wool in Eastern Europe, foamed plastic is projected to account for the majority of value gains globally through 2023. Foamed plastic is the most used insulation material in the Asia/Pacific region which will strengthen the material’s leading position.
