Noise protection

If it is necessary to limit the noise level, it is necessary to ensure the sound pressure level at a given distance from the generator body. Next, you need to design a noise-proof casing to ensure the specified level of noise outside the casing. Do not try to get this noise level unreasonably low, as this will result in too much cost.

The use of resilient genset mountings combined with conventional exhaust, intake fan and radiator fan noise control technology will reduce genset noise to an acceptable level in many applications. If, after taking these measures, the noise level is still too high, it is necessary to use the acoustic covering of the room or generator unit. Sound barriers can be installed around the generator set. The generator walls can be covered with sound-absorbing material, the generator unit can be enclosed in a special sound-absorbing casing (Fig. 8.1.)

In most cases, it is necessary that the inlet and outlet air openings are equipped with sound absorbers. If it is necessary to protect the working personnel from the direct impact of the noise of the generator unit, the equipment and the control panel can be located in a separate room.
