在海洋噪声测量及换能器校准测量中,都需要频率范围宽响应平直的水听器。这种水听器一般是采用劲度控制的压电元件制成的。 图1是我们所作的水听器的结构示意图。它是
In both marine noise measurements and transducer calibration measurements, a hydrophone with a wide frequency response and a straight response is required. This hydrophone is generally made of a stiffened piezoelectric element. Figure 1 is a schematic diagram of the structure of our hydrophone. it is
