查询词典 plant oil

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.
