    Abstract - (Show below) - (Hide below)

    Describes a primary method of determining the pressure sensitivity to establish a reproducible and accurate basis for the measurement of sound pressure. and pertains to laboratory standard microphones meeting the requirements of ANSI S1.15-1997/Part 1 (R2001) and other types of condenser microphones having the same mechanical dimensions.
