According to the acoustic principle, the comprehensive measures of sound insulation, noise elimination and absorption are adopted to reduce the reverberation in the room and reduce the noise leakage, noise reached about 60 decibels, the unit output power is not damaged, all materials are non-flammable explosives. In addition, in order to avoid the harmful effects of diesel generator emissions on the environment and the human body, black smoke treatment and deodorization can be achieved by means of exhaust gas purifiers and ground ventilation equipment to reduce energy consumption, at the same time, strong structure, simple maintenance.
