Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission; the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB, but also adapt to the gas's characteristic involved with H2S, CO, and other poisonous components without supplied mandatory ventilation; locating the noise absorbers on the walls and ceiling of workshop can reduce noise by 8 dB; the exhaust silencer's elimination volume can reach above 30 dB which is designed in accordance with the exhaust noise spectrum characteristic of gas-combustion generator. By the combination of these measures, the noise of the gas- combustion generator will be under effective control, so that the gas power plant's noise pollution problems can be resolved.

通过选用耐油性好的橡胶隔振器减少固体传声，可降低噪声约2 dB；设置半封闭式机组隔声屏障可降低生产车间工作区域内的噪声达13 dB，并且适合瓦斯发电气源中含有H2S、CO等有毒有害气体的特点，不需增加强制通风措施；在生产车间四周墙壁和顶棚上敷设吸声体，最大可降低空间噪声8 dB；根据瓦斯发电机排烟噪声频谱特性设计的阻抗复合式消音器的消音量可以达到30 dB以上。
