A computer program is described which calculates the pressure sensitivity of microphones based on measurements of the electrical transfer impedance in a reciprocity calibration set-up. The calculations are performed according to the International Standard IEC 6194-2. In addition a number of options allows the user to improve his calculations by introducing corrections not yet implemented in IEC 61094-2, such as corrections for the influence of radial wave-motion in the couplers. A specil feature, the ability to refer the calculated sensitivities to reference environmental conditions by means of the complex pressure- and temperature coefficients for B&K Types 4160 and 4180 microphones, is included in the program.
