Abstract
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.
