1.前言声压标准是用互易技术通过实验室标准传声器的校准来实现的。该技术的原理是两耦合传声器(其中之一作为发射另一作为接收)由电和声的转移阻抗之比给出。声转移阻抗可由耦合几何量与声传播媒质的参数计算出,电转移阻抗通过测量确定。国际标准详细描述了互易技术中有关声转
1. Introduction The sound pressure standard is achieved using reciprocal technology through calibration of laboratory standard microphones. The principle of the technique is given by the ratio of the transfer impedance of the electric and the acoustic to the two coupled microphones, one of which as the other for emission. Acoustic transfer impedance can be calculated from the coupling geometry and parameters of the acoustic media, and the impedance of the electromigration is determined by measurement. International standards describe in detail the soundtransfer in reciprocal technology
