description The invention discloses an accurate measurement method for pool reverberation time. The method mainly comprises a hydrophone and a reciprocal transducer, wherein the hydrophone and the reciprocal transducer move on two sides of a pool respectively, sound field information of a reverberation pool is acquired, and the reverberation time of the reverberation pool is calculated by combining reciprocity of the reciprocal transducer with the acquired sound field information. More space information is used, the requirement for the sound source level of a transmitting transducer is lower, and a test result has higher accuracy; and the method is used for measuring the pool reverberation time in a research project, the measurement result is basically consistent with a result of an interrupt sound source method, the effectiveness of the method is proved, and the method can be gradually applied to parameter calibration of reverberation fields. 本发明公开了一种水池混响时间的精确测量方法，主要包括水听器与互易换能器，水听器与互易换能器分别在水池的两侧移动，采集混响水池的声场信息，利用互易换能器的互易
