为了测定压电换能器向水中辐射的总声功率输出,研制了一套测量装置。该装置由电子微量天平、消声水槽和反射靶悬吊系统组成。在1～5MHz频率范围和输出声功率0.2～20W范国内,测量不确定度优于±5％。
In order to measure the total acoustic power output of the piezoelectric transducer to water, a set of measuring devices was developed. The device consists of an electronic microbalance, anechoic sink and reflector target suspension system. In 1 ~ 5MHz frequency range and the output sound power 0.2 ~ 20W Fan domestic, the measurement uncertainty is better than ± 5%.
