The invention discloses a ship noise source discretization noise control method, and belongs to the technical field of noise control. According to the method, a larboard or starboard noise source discretization device is adopted for independent control, the noise source discretization device is divided into a lower-layer mechanism and an upper-layer mechanism, and the lower-layer mechanism and the upper-layer mechanism on the same board are independently controlled. The noise source discretization is started from the noise source, and the noise influence of the high noise source on the cabin of the residential area is eliminated on the premise of ensuring that the exhaust air rate of each sanitary place is not changed. Exhaust air of sanitary places of every two layers of deck cabins is combined together and is exhausted through a small pipeline fan; the noise level of the pipeline fan is generally 45-55 decibels and is much smaller than 75-110 decibels of an axial flow type large fan, and the pipeline fan can be arranged in a corridor or a storage room of a residential area and has little influence on a cabin of the residential area. According to the method, the influence of the exhaust fan on the internal noise of the cabin of the residential area is eliminated, the noise level is effectively reduced, and the comfort of cabin living is greatly improved.
一种船舶噪声源离散化噪声控制方法,其属于噪音控制的技术领域。该方法采用左舷或右舷噪声源离散化装置独立控制,噪声源离散化装置分为下层机构和上层机构,且同舷的下层机构和上层机构独立控制。噪声源离散化从噪声源处着手,在保证各个卫生处所排风量不变的前提下,消除高噪声源对居住区舱室噪声影响的方法。每两层甲板舱室的卫生处所排风合在一起,经过小型管道风机排风;其噪声水平一般在45~55分贝之间,比轴流型大风机的75~110分贝小了很多,且管道风机可以布置在居住区走廊或者储藏室内部,对居住区舱室的影响很小。该方法消除了排风机对居住区舱室内部噪声的影响,有效降低了噪声水平,极大提高了舱室居住的舒适性。
