A method of directly evaluating the impulse response of a reciprocal electroacoustic transducer is presented. The method is essentially the time‐domain analog of the conventional (frequency‐domain) reciprocity method. The transient response of a coupled pair of identical transducers is used to compute the impulse response of either of the pair. A numerical method of obtaining solution is presented and is shown to be equivalent to the numerical solution of a real convolution integral equation. First, an approximate solution for one member of the pair of identical transducers is obtained. Then, a more precise solution is generated by minimizing the squared error between the actual response of the coupled pair and the one obtained by convolving the approximate impulse response with itself.The method was tried on two pairs of condenser microphones, the microphones within each pair being very nearly identical. A pair of Western Electric 640‐AA microphones were tested with the grids both on and off, and a pair of Bruel and Kjaer type 4131 microphones were tested with the grids on an off and with grids equivalent to those on the W.E. 640‐AA both on and off.Two unsatisfactory solutions resulted when W.E. 640‐AA grids were used on the transducers. Three solutions were satisfactory, even though each contained slight negative drift for large values of time. One solution contained no appreciable error in its entire time course.
