摘 要:在测量水下潜航体辐射噪声时,一般将水听器悬浮水中进行测试。在测试中,水听器随海流影响会发生飘移,水听器与水下潜航体距离会发生变化,在距离折算上存在误差。针对该问题,有人提出了将水听器预先安装在测试器水底,这样水听器与水下潜航体的距离是预先知道的,在计算声传播损失的时候就会大大减少误差。基于此,本文以其为根据,对一种海底底质透声性能测量方法进行探究,以期对相关方面的技术研究有所帮助。When measuring the radiated noise of underwater submarine,hydrophones are usually tested in suspended water.In the test,the hydrophone will drift with the influence of ocean current,and the distance between the hydrophone and the underwater submarine will change. There are errors in the conversion of the distance between the hydrophone and the underwater submarine. To solve this problem,it is proposed that the hydrophone be pre-installed at the bottom of the tester,so that the distance between the hydrophone and the underwater submarine is known in advance,and the error will be greatly reduced when calculating the acoustic transmission loss. Based on this,this paper explores a method for measuring the sound transmission performance of seabed sediment,with a view to helping the related technical research.
