Hidier power source is introduced: dieselgenerator to include engine exhaust noise, the intake noise, combustion noiseof machinery to the work of the engine parts, noise, and room walls (includingthe ground, roof, door and window) reflection noise.

　　For sound source characteristics andgovernance effect of equipment noise generator control, are computer roomequipment and environmental noise monitoring in before and after treatment.Very high noise level units, generally 90 ~ 115dB. Because the diesel generatorroom sound insulation ability is not ideal, the engine room and environmenthave exceeded the standard.

　　Hidier power spectrum characteristic formastering sound source, the spectrum of single sound source determination. Fromthe noise spectrum curves can be seen: the frequency generator noise isbroadband, peak frequency is 63 ~ 1000Hz, the low frequency sound diffractioncapability is extremely strong, so cause some difficulty to the treatmentengineering.

　　Hidier Power Group (Beijing) Co., Ltd.provide high-quality power unit price, welcome to inquire the latestpreferential generator!
