What is useful and what is dangerous surrounding "noise"
Today the architecture in the cities given great importance: we learn to build smart and green homes, but few people think about the sounds that constantly surround us within them.
Each place has its own recognizable sound: at the cafe, subway, restaurants and even the bus. The sounds are constantly affecting us and can influence not only on mood but also on health.
In this article we'll talk about "everything but music" — the diversity of sounds that surround us, hinder us, or, conversely, help.
The noise around us: our friend and enemyOften we get used to the sounds around us and stop paying attention to them, but if they suddenly disappear, we will notice a huge difference. Mega-cities and cities constantly "sound", creating a cacophony, more like noise. Journalist and Professor at new York University George Foy (George Foy) conducted its own experiment to find quiet places in different countries, and came to the conclusion that even in the Antarctic and the most remote forests of the Amazon sooner or later you invariably will overtake the noise of flying aircraft. Even the most remote corners of the planet today "littered" with human noise.
Approximately the same conclusions came Bernie Krause (Bernie Krause), the American bioacoustic, recording engineer, musician and environmentalist. He takes recordings of nature sounds, or soundscapes, and if 40 years ago to produce one hour of "usable" content, it needed only 10 hours of recording time, today this figure reaches 1000 hours. Birds away from their usual habitats, and their place on the record is the sounds produced by humans.
Therefore, silence is becoming a resource for which people are willing to pay: noise cancelling headphones, the soundproofing in the apartments. The city can be filled not just with sounds and bad noise. And the noise, in fact, is a vibration that can adversely affect not only a person's mood but also his health. For example, doctors have been proven relationship between hypertension and living near a permanent source of noise. But as a city resident to cope with the negative effects the sounds of the city?
A possible solution was proposed by the company Meyer Sound, which as the experiment was installed in a restaurant in Berkeley, California, a special system of noise suppression. It consists of 123 microphones and speakers located throughout the restaurant. The system records the original sound platform, and after computer processing the modified sound gets back into the room.
The engineer can control the sound inside the room, and guests get a chance to talk without having to shout over the noise around. This technology is typically used in large venues, however, can potentially be in demand not only in restaurants but also in many places with a large crowd of people.
From the noise it is impossible to hide even at home. On the one hand, the sounds of the street can fill the room and "expand" its borders (which is why the installers don't suggest too carried away by the soundproofing of the room — completely devoid of the "sound" the place of pressing and causing extreme discomfort). But if the apartment faces a busy street, even with closed Windows you can hear night riders, the cries of late revelers, rumbling trams, operating road equipment... Such unpleasant sounds that penetrate in a private space, a huge amount.
To cope with them can not only soundproofing, filling the room with furniture and textiles, and gadgets — so even in 2013, developers presented to the public the project Sono is a device, overwhelming external vibrations and mountable to the window. It can "create the silence" and to operate in the mode blocker of the noise, losing the good ear sounds — soothing sound of rain and birds singing. By the way, some devices of this type, you can even take with you to restaurants or travelling. Silence is not only sold, but also becoming mobile:
"Sound health,"Noise can harm human health, leading to chronic fatigue and stress. But the sound is often used for the benefit of man. Today in the West is actively spreading the use of sound to aid in rehabilitation, although the idea is not new and came from the ancient cultures of South America, India and China. No magic here, just well-chosen sounds can affect a person's mood. But the main effect, according to the founder Organizations of music therapy in California Amrita Cottrell (Cottrell Amritta) can be achieved through relaxation.
We live in constant tension, which can worsen pain or lead us in a depressed state of relaxation and cleans unnecessary stress and improves overall health. Now scientists collect data on the possible use of sound therapy when working with patients with delays in physical and mental development, communicative and mental disorders, as well as children and the elderly — the number of studies on this subject is gradually increasing.
Another quite rational explanation of the action of such methods — the placebo effect. According to Dr. Vijay B. VAD (Dr. Vijay B. Vad), a specialist in sports medicine from the Hospital of clinical surgery at new York, 35% of patients felt relief from back pain after receiving placebo. Therefore, if a person believes in the healing power of sounds, this method can act similarly.
Sound waves of different frequencies are also used in traditional medicine. For example, ultrasound. Moreover, it is used for disinfection of medical instruments, drugs and food (usually as supplements to other methods of disinfection) and to accelerate tissue repair after injury and pain treatment by physiotherapy. Although not all doctors recognize the effectiveness of ultrasound for regeneration, a certain effect is precisely the warming and mussirovanie the area of impact.
Another application of ultrasound, which is still under study — the impact on cancer cells. Although therapy high-intensity focused ultrasound at this stage revealed a lot of side effects, there are patients that this treatment helped. But the method is still applied as experimental, and clinical trials are still not over.
But the effectiveness of ultrasound (US) no one no doubt. Ultrasonic waves allow physicians to image internal organs and are considered safe (compared to x-rays). But not only is ultrasound used in the diagnosis. The usual sounds of our body too much to tell doctors about a patient's health. With a simple stethoscope, a skilled doctor can recognize certain symptoms — just because you know how "sounds", for example, a healthy heart (this material includes audio recordings of such sounds).
Despite the fact that the noise pollution, we have learned to use many around us sounds good. Although not all methods of sound recognized by official medicine, one thing is for sure: well-chosen sounds or favorite music can definitely enhance the mood and help us relax after a hard working day. published
