Noise is a sound that is too loud and can easily cause irritation or even be harmful to human health.

The human subjective factor often plays a decisive role in distinguishing noise. The same piece of music is a beautiful sound to those who are enjoying it. But for those who are studying, resting or need to concentrate on their work, it may be noise.
Like the lady dancing to the music in the square and the student who can’t concentrate on his homework in the neighbouring residential building, one is enjoying herself and the other is suffering in silence.

It can be put this way: any sound that interferes with people’s normal activities such as resting, studying and working is classified as noise.
Noise is divided into high and low frequency noise.

The energy of high-frequency noise, such as horns, sirens and screams, decays rapidly as the distance increases or obstacles are encountered.

The energy of low-frequency noise, such as living, traffic and construction noise, decreases slowly, and the sound wave is long, so it can easily pass through obstacles, run over long distances and penetrate walls directly into the human ear.

Low-frequency noise is more difficult to isolate than high-frequency noise and is more likely to have an impact on people’s lives.

Noise pollution occurs when noise adversely affects people and their surroundings.
The sources of noise pollution are manifold:
The noise of the morning and night markets, the sound of shop horns, the noise of the crowd and other living noise; aircraft roar, ship whistles, train rumbles, car horns and other traffic noise; and construction sites on the cacophony of all kinds of noises.
For people who need a quiet environment, these sounds are essentially no different from the squealing of a pig.
These are not easy to notice the details of life are often ignored by us, most do not realise that life noise has been quietly damage our quality of life and health.

Numerous studies have pointed out that, in addition to causing damage to hearing, prolonged living noise can have far-reaching negative effects on a person’s physiology and psychology.

Noise stimulation can lead to abnormal blood pressure and heart rhythms, especially for people with high blood pressure and heart disease.
For children, who are more malleable, the effects of living noise are even more pronounced.
Analyses suggest that prolonged exposure to noise can lead to deficits in visual attention and sustained attention, diminishing their problem-solving abilities and even leading to reduced intelligence, dyslexia, poor memory and boredom.
When a child who has been quietly doing his homework gets progressively cranky, it may not be the maths problem that makes him snap, but the dancing amazons downstairs.
Under the influence of continuous noise, the excitation and inhibition process of the cerebral cortex will be imbalanced, causing confusion of conditioned reflexes, manifested as headache, dizziness, insomnia, drowsiness, easy to fatigue, easy to be agitated, memory loss, lack of concentration, slow reaction, etc., and in severe cases, it will also induce a decline in physical fitness and hair loss.
Therefore, to avoid the tragedy of baldness at a young age, it is also important to create a quiet rest and work environment.

So how do you keep your family away from all that noise?

To put it simply, you have to spend money.
Firstly, you can start from the decoration, thick and rough walls can effectively reduce the noise.
Decoration can choose wallpaper and other sound-absorbing decorative materials, but also the use of cultural stone and other decorative materials, the wall surface to make some rough.
In addition, walls and ceilings can use sound insulation materials, such as mineral wool sound-absorbing boards.
The street side of the window converted into “soundproof windows”, such as double-paned windows, can be effective sound insulation, the choice of insulating glass, sound insulation effect is also better.
As for furniture, wooden furniture fibre porous so that it can absorb noise, the purchase of furniture can be appropriate consideration, the use of cork flooring in the decoration is also an effective choice.
If these effects are not good, you can buy a noise-cancelling headphones and rest with headphones.

Of course, if it does not work, and really can not stand the surrounding noisy environment, moving is the direct method.
