6.52  pressure sensitivity; voltage sensitivity. Of an electroacoustic transducer for sound reception, for a specified frequency, quotient of the output open-circuit voltage by the sound pressure acting uniformly on the part of the transducer designed to receive sound. Unit, volt per pascal (V/Pa).

Annotation              Root-mean-square voltage and sound pressure are usually specified. If the load impedance is other than that of an open-circuit, the load impedance is specified.
