Embodiment Construction
[0035] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0036] The present invention mainly comprises the following steps:
[0037] Step 1, take a typical uniform rubber layer sample as the acoustic cover layer sample, such as figure 1 As shown, the acoustic coating sample 4 is placed in the middle of the tube body in the hydroacoustic planar acoustic waveguide. There is a certain liquid column height (more than 1m in the present embodiment). One end (lower end in this embodiment) of the tube body cavity of the hydroacoustic plane acoustic waveguide is provided with a transmitting transducer 7, and two hydrophones are arranged between the transmitting transducer 7 and the acoustic coating sample 4: 3# water Hearing device 5, 4# hydrophone 6, two hydrophones are arranged between the liquid surface 1 on the acoustic cover sample 4 hydroacoustic plane acoustic waveguide: 1# hydrophone 2, 2# hydrop...
