Noise

Road transport is the main source of noise in big cities. And this is not only a problem of roadside residents, but the drivers themselves. Noise level of road transport is very high. After such a background noise of the day you will hardly have good and qualitative sleep. In such cases, after awakening, people feel fatigue, headaches, palpitations and often heartbeat. Regular lack of rest doesn't let the man recover after working hours and as a result leads to chronic overstrain - one of the most common causes of many diseases. In addition, constant fatigue adversely affects the ability of safe vehicle management.

To reduce road noise is possible by means of noise insulation in the car or reducing vibration of the car. It is not desirable to use a forward-flow silencer: it increases low-frequency noise, which influences human nervous system.
