船舶机舱噪声以轮机员主要活动区层——底层及平台甲板处为主要评价依据。根据我们对不同船型测得的数据表明,各船机舱噪声级(A)均在90～100分贝,而多数在100～105分贝,个别船还要高。由此说明多数船舶的机舱噪声是严重的,经分析研究我们在整个声频区域巾取得了噪声减低量参考曲线,如图1所示。本文将对机舱集控室噪声控制的试验研究加以叙述。 The noise of ship’s engine room is mainly evaluated on the basis of the main activity zone of the engineer-the ground floor and the deck of the platform. According to the data we measured for different ship types, the cabin noise levels (A) for all ships were 90 to 100 dB, while the majority were between 100 and 105 dB, with individual ships even higher. This shows that most of the ship’s cabin noise is serious, after analysis we have made in the entire area of ​​?? the noise reduction towel reference curve, shown in Figure 1. This article will be on the cabin control room noise control experimental study will be described.
