| Abstract: | Ths paper introduces a transducer for measuring suspended sand particles, and a shading principle to eliminate the blind point in the near field of sound source axis. By adopting the front matching layer and back liner, the transducer's fraquency band becomes 2. 1 times wider and the sensitivity 1. 6 times higher. The transducer is characterized by simple structure and portability. |
