摘要
Abstract
The underwater sound signals collected by the buoys are studied. A signal processing method is applied to separate the ocean wave sound from the original measured signals with hydrophones. Each measured hydrophone signal of the 16 channels is transformed into audio signal based on the parameters such as sampling frequency, sampling time and so on. Then, the audio signal is played and classified into different segments with different noise characteristics by human ears. These segments with different noise characteristics are extracted from the original time-domain signals for frequency spec-tral analysis, and their characteristic frequencies are obtained. Finally, the digital filter is designed to de-noise the ocean wave sound. Experimental results show that the ocean wave sound components are effectively suppressed from the measured original signals by hydrophones.关键词
