将一固定式声检测站安装在水深小于12m的水域,用一些已标定过的频率覆盖范围为45Hz～50kHz的声源,按静止或移动方式用该检测站进行了广泛的测量,以预报它们的绝对声源级。本文介绍这些测量结果,并指出如何使用一组经理论验证的测量结果,将传统的201gR传播规律改进为依赖于频率和距离的修正算法。最后绘出了用此算法得到的结果。它表明在对正常测量条件下存在的各种影响综合进行时间和空间平均时,浅海检测站也能给出辐射声源级的高精度预报。 A fixed acoustic test station was installed in a water depth of less than 12 m and a number of calibrated frequency sources covering a range of 45 Hz to 50 kHz were used to perform a wide range of measurements at the test station either stationary or mobile to predict them The absolute sound source level. This article describes these measurements and shows how to use a set of theoretically validated measurements to improve the traditional 201gR propagation law as a correction algorithm that relies on frequency and distance. Finally draw the results obtained with this algorithm. It shows that the shallow sea detection station can also give high-precision prediction of the sound source level when various influences existing under normal measurement conditions are integrated in time and space.
