| Abstract: | The study of sound absorption of turbid seawater has great significance for improving the performance of sonar working in coastal environment.Based on reverberation method,an experimental system for sound absorption of coastal turbid water has been designed.Theoretical analysis shows that the experimental system meet the requirements of sound absorption measurement using reverberation method.Xiamen beach sediment and seawater are mixed to simulate the coastal turbid water,and the sound absorption of the sim... |
