The equipment noise came from oil pump, electric machine, valve body during gas transimission at the gas station. After site testing, the soundproof box noise level is 90dB. After closing the door, the noise level is 84dB. The effect of soundproof box' decreasing noise level is noly 6dB. This result can not meet the demand of city noise reduction standard. But after installing our soundproof box, it not only meet the noise level standard, but also has fire prevention function.
You can reference the following pictures, which are test result.
