摘要：
This 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 frequency band becomes 2.1 times wider and the sensitivity 1.6 times higher. The transducer is characterized by simple structure and portability.
