A technique for estimating the effective acoustic parameters of the bottom in shallow water areas under ice cover has been developed. The methodology compares the experimental and simulated dependences of the sound field amplitude on depth at a distance from the source about an order of magnitude greater than the depth of the water area. The effective parameters are the values of the sound speed in the bottom, density, and attenuation coefficient of acoustic waves, which provide maximum agreement with experimental data in the calculations. The methodology was tested in a field experiment on Lake Baikal and can be recommended for developing autonomous acoustic monitoring systems.

贝加尔湖底部的声学参数

已经开发出一种估算冰盖下浅水区底部有效声学参数的技术。该方法在距离声源一定距离（比水域深度大一个数量级）时，比较了声场幅度对深度的实验和模拟依赖性。有效参数是声波底部的声速，密度和声波的衰减系数，在计算中与实验数据具有最大的一致性。该方法已在贝加尔湖上进行了现场试验，并被推荐用于开发自主的声学监测系统。
