Presently, scientists of the different countries try to find out what influence of noise on human health, and whether it is necessary to take measures for protection against the similar phenomena. It is not surprising, our organism is influenced by various waves including sound. The problem is so relevant that even the special term – acoustic ecology appeared.
Influence of noise and vibration on a human body
Noise level can be estimated in decibels (DB). For the person the sound background in limits up to 45 DB is considered normal. If this level is exceeded, then noise and vibrations from a sound wave begin is destructive to affect a human body.
Of course, the first that It should be noted, this negative impact of loud sounds aurally. The more often the person listens to music at an extreme loudness or is in too noisy zones, for example, in shops of the plant, subjects his hearing becomes less sharp. Thus, it is possible even to become deaf, and it only one of negative influences of noise on an organism.
Besides, loud sounds influence work of nervous system of the person, sight and a vestibular mechanism. The person who is affected by noise and sound vibrations cannot concentrate, thought processes slow down, and the attention dissipates. Such influence of noise on a human body is very dangerous. Loud sounds and vibration not seldom lead not only to home and professional accidents, but also to blood circulation violation, heart attacks and strokes.
To protect itself and the relatives, it is necessary to remember that noise should not exceed 40 DB, it is the level of a quiet conversation not with voices raised. Also it is worth refusing use of a subwoofer. Low frequencies can cause violations in work of heart and blood circulatory system.
