“10”船停泊机间布置在后居住舱前上方。当4135型停泊柴油发电机运行时,产生强烈的振动与噪声,影响后居住舱人员的工作和休息。 1983年3月我们对“10”船(系武昌造船厂80年建造)进行噪声与振动测量,停泊机间噪声为104dB(A),在停泊机间下方后住舱床铺处为75dB(A)。这大大超出船舶噪声标准中卧室要求60～65dB(A)的指标。从测得的噪声频谱图(图1)可以明显看出停泊机间噪声主要峰值在63～125HZ,500～1KHZ。后住舱各测点处噪声不均匀,在停泊机间下方为75dB “10” boat mooring room arranged in the top of the rear of the living room before. When the 4135 parking diesel generator is running, it produces strong vibration and noise, affecting the work and rest of the occupants of the rear cabin. In March 1983, we carried out noise and vibration measurements on the “10” (80-year-old Wuchang Shipyard) noise among the parking spaces at 104dB (A) and at the rear of the parking spaces at the rear of the cabin at 75dB (A) . This greatly exceeds the standard of 60-65dB (A) required by the bedroom in the ship noise standard. From the measured noise spectrum (Figure 1), it can be clearly seen that the main peak of noise among parking machines is in the range of 63-125HZ and 500-1KHZ. After the cabin at the measuring point at the noise is not uniform, below the parking machine is 75dB
