Some people may well tolerate loud noise but there are many reasons to stay away from it. Noise is one of human life's stressors. When a person exposed to loud noises, the blood vessels constrict and less blood flows to the organs. Noise is like passive smokers. People aren't aware that noise is affecting their health.Noise are unpleasant, annoying, and distracting sounds. Most kinds of noises are produced by vibrating objects that send out irregular vibrations at irregular intervals.
Dutch researchers also found out that people living on noisy streets suffer more high blood pressure than those in quieter areas. According to them, noise can cause people to get angry more easily, and provoke depression and organic diseases particularly when under stressful situations. Younger people are more at risk. It was reported that mothers who lived near airports bore more premature and underweight babies.
The researchers also agree that noise from traffic, night clubs, building firms, lively restaurants with videoke, discos and even background music- is enough to make some people's muscles tense, their pupils dilate, their heartbeat increase, their arteries constrict and their blood cholesterol and adrenalin levels rise. To much exposure to noise can also cause deafness.
