  6. Here a number of factors must be taken into consideration, such as the environmental standard of the area where the engine room is located, the fender structure of the engine room as well as the engine type, power level and the cooling air volume, etc. the core of the overall control is the concept of " equal sound insulation ", which means to apply a closed fender structure to isolate the engine unit from outside parts so as to cut the outward sound radiation

    經過多年來與環保部門的合作，對油機房進行消噪聲處理，積累了一些治理經驗，主要是必須根據具體的機房項目來確定相應的控制方案，這其中應考慮機房所在區域的環境標準，機房圍護結構形式及油機機型、功率、冷卻風量等因素。綜合控制的核心是等隔聲概念，即用一封閉的圍護結構將機組與外界隔離開來，減少聲源對外的聲輻射。
