标准水听器 用于液体中（主要是水中）作声学测量的电声接收换能器（见电声换能器），它的灵敏度（自由场灵敏度或声压灵敏度）是经过准确校准的，其声学性能应符合所规定的要求。目前在各种水听器中只有用压电晶体或压电陶瓷作敏感元件的压电型水听器适合作标准水听器。 国际电工委员会（IEC）制定的国际标准"IEC-500（1974）《标准水听器》"对压电型标准水听器的声学性能作出规定, 如: 灵敏度应在－180～－200dB(0dB1V／??Pa)之间；频响特性在三个十倍程范围内起伏不大于±1.5dB;动态范围大于60dB；时间稳定性为一年校准一次而无可觉察的变化；水平方向的指向性是无向的，其偏差不超过+0、-3dB；以及灵敏度随静压（水深）、温度等的许可变化范围。 中国的国家标准GB 4128-84《标准水听器》中规定了用于 1Hz～100kHz的压电型标准水听器的主要性能参量和技术指标。根据使用目的和校准准确度分成两级：标准水听器(一级)和测量水听器(二级)。标准水听器是用作实验室标准,进行量值传递及作精密的声学测量,规定:灵敏度应大于-205dB(0dB1V/??Pa)；用一级标准方法进行校准,低频段用耦合腔互易法和压电补偿法,高频段用自由场互易法；其准确度低频段优于±0.5dB,高频段优于±0.7dB；灵敏度频响不均匀性小于±1.5dB的范围要求大于三个十倍程;其水平和垂直指向性均以－3dB波束宽度来衡量，分别为大于30°和15°；动态范围应大于60dB；对温度、静压和时间的稳定性也都有一定的要求。测量水听器是用作实验室或工厂的测试标准，进行一般声学测试或产品检验,规定:灵敏度应大于-210dB(0dB1V/μPa)；用二级标准方法进行校准，低频段用振动液柱法或密闭腔比较法,高频段用自由场比较法,其校准准确度低频段优于±1.0dB,高频段优于±1.5dB;灵敏度不均匀性小于 ±2dB的频率范围应至少有三个十倍程以上；水平指向性应是全向的（起伏小于2dB）,垂直指向性给出不少于四个频率的指向性图案；动态范围应大于60dB；稳定性的要求比标准水听器低一级。
