我国江河众多,多可四季通航,随着国民经济的发展,水运事业将有较大的发展.船舶噪声,特别是内河船舶驶经城市航道的噪声对城市的影响,已开始受到人们的注意.为此,本文通过对运输船舶的声学调查,以及在不同航道上对船舶辐射噪声进行监测,总结出船舶噪声的分布规律与特性,提出民用运输船舶噪声质量评价的表示方法,和有关噪声控制措施的设想,以供船舶设计、航运环保、噪声监测 与控制参考.
Due to the large number of rivers in our country and the availability of more seasons in the four seasons, with the development of the national economy, there will be greater development of the water transport industry. Ship noise, especially the impact of inland watercourses passing by urban ships on ships, has begun to attract the attention of the people. Therefore, this paper summarizes the distribution rules and characteristics of ship noise through the acoustic survey of shipping ships and the radiation noise of ships in different waterways, and presents the method of noise quality assessment of civil ships and the related noise control measures The idea for the ship design, shipping environmental protection, noise monitoring and control reference.
