Vibration is mechanical oscillations in the field of subsonic and sound frequencies. The person feels vibration of a surface if the range of fluctuations from 12 - 8000 Hz. It is considered that long impact on a human body of vibration is unhealthy.
Instruction
1. Vibrations miners, miners, road builders and other representatives of professions which directly face in work with heavy machinery are exposed. In houses transport passing a row, various plants, engineering processing equipment of buildings is a source of emergence of vibration. Each resident of the large city is affected by vibration. The most noticeable and intensive for the person is vibration which proceeds from the subway and trains.
2. If you want to check vibration level in the apartment, then can order special a professional research. By results of such research you receive minutes of the conducted laboratory researches and the expert opinion. Experts will make the ecopassport and will make recommendations how to fix the revealed problems.
3. You can measure vibration and independently, by means of the vibrocount or the vibration pen. The vibration pen is arranged from the sensor which accepts vibration, the preliminary amplifier, the registering device. The sensor will transform all measured mechanical oscillations to electric which move on the special registering device, and the measuring amplifier, the frequency analyzer and the recorder will show vibration level. For measurement of vibration it is possible to buy K001 brand vibration pens, they are released by the Vibropribor plant. This device registers vibration amplitude to 1 mm in frequency range from 2 to 200 Hz.
