随着船舶舱室噪声限值标准的相继提出和对噪声控制的要求,世界上许多国家都先后提出有关噪声测量方面的规定,有的针对民用运输船舶或渔船,有的针对工程船或特种船舶。各部门对船舶噪声测量的要求有所不同,主要是为了取得正确而可比的数据,对船舶自身不同的运行时期或船舶之间进行分析和比较,归纳起来噪声测量的目的大致有以下几方面: 1.为了了解船舶噪声的危害,为确保广大船员的健康或舒适性,改进服务质量、提高营运安全。 2.为研究降噪防噪措施,或论证在某艘船上噪声控制和声学处理效果。
With the successive proposal of noise limits for ship cabins and the requirements for noise control, many countries in the world have put forward the requirements on noise measurement one after another, some for civil transport vessels or fishing vessels, and some for engineering vessels or special vessels. Different departments have different requirements for ship noise measurement, mainly in order to obtain correct and comparable data. The analysis and comparison of different periods of operation of the ship itself or between ships can be summed up. The purpose of noise measurement is roughly as follows: 1. In order to understand the hazards of ship noise, to ensure the health or comfort of the crew members, to improve the service quality and to enhance the operational safety. 2. To study noise reduction and noise prevention measures or to demonstrate the effects of noise control and acoustic treatment on a ship.
