Abstract：To investigate the static pressure coefficient and temperature coefficient of the laboratory standard microphones, a static pressure and temperature control system was developed based on the coupler reciprocity system. The sensitivities under different pressure and temperature conditions were dealt with application of Straight Line Fitting Method and the pressure and temperature coefficient at different frequency was obtained. The results show that in low frequency the coefficients hold the line, and at half of the resonant frequency of diaphragm, the pressure coefficient gets its max., while the temperature coefficient gets its min.
