| 摘 要： | 针对船舶舱室内的噪声问题，利用阻性吸声材料泡沫铝无毒、阻燃、无粉尘、工艺性能好的特点，模拟舱室环境，对舱室进行了噪声治理。模拟结果表明加泡沫铝后，可以使舱室空气噪声平均降低约10dB，具有显著的降噪效果。

| Abstract: | In this paper, the noise in watercraft cabin is discussed. The noise control in the space was simulated by using the damping sound-absorption material of foam aluminum, which has the characteristics of non-toxic, inflaming retarding, no dust, and good processing,etc.. The simulation results show that the noise in cabin can be reduced 10 dB by using the foam alumi- num. The effect of noise control is obvious. |
