Because electromagnetic and light waves cannot transmit over long distances in water, underwater acoustic wave is the best tool for transmitting information. The underwater acoustic transducer is an essential front-end device in sonar. Its function is to complete the mutual conversion between the underwater transducer and electrical energy, achieving the reception and transmission of sound waves. The contents of this course project include: transducer production, transducer operating frequency band measurement, voltage response measurement, transducer sensitivity measurement, transducer receiving directivity measurement, and sonar signal processing. The course lasts 6 days.

由于电磁波和光波无法在水下远距离传输，因此声波是在水中探测目标、传递信息的最佳工具，声纳是水下最有效的检测设备。水声换能器是声纳中必不可少的前端设备，用于完成水下换能器和电能的互相转换，实现声波的接收和发射。本课程项目内容包括：换能器制作、换能器工作频段测量、电压响应测量、换能器灵敏度测量、换能器接收指向性测量，以及声纳信号处理等课程，课程时间6天。
