对舰船电子设备显控台的噪声源进行具体分析，并对某型显控台的噪声声压级水平进行理论分析计算，得出理论分析结果不能满足舰船电子设备噪声验收限值的要求。根据舰船设备电子设备噪声测量方法的要求，对显控台的噪声水平进行试验检测，并对试验结果进行声压级分析和频谱分析，结果表明，风机是显控台的主要噪声源，最后，从风机优化选型和风机壳体优化设计方面提出具体改进措施，降低显控台的噪声水平。
Firstly, combined the noise situation of a certain type of ship's electronic equipment display console, make full use of theoretical analysis and calculation. Obtained the level of noise and sound pressure of this type of display control station cannot meet the requirements of Class C equipment in the ship's electronic equipment noise acceptance limit. Secondly, according to the requirements of noise measurement standards for shipboard electronic equipment, the noise conditions of this type of display console are tested and analyzed, and the sound pressure level analysis and spectrum analysis of the test results are performed. The fan noise is the main noise source of the display console. Finally, put forward specific improvement measures from the aspects of optimal selection of fan and optimized design of fan casing to reduce the noise level of the display console.
