6.74 dynamic range (of an electroacoustic transducer). The range in operating amplitude between a minimum threshold level that is set by the inherent noise and an upper limit set by tolerance in nonlinearities or distortion. Unit, decibel (dB). Annotation 1...
6.73 equivalent noise pressure level. Of a transducer, twenty times the logarithm to the base ten of the ratio of the root-mean-square of the equivalent noise pressure to the stated reference pressure. Unit, decibel...
6.72 equivalent noise pressure; inherent noise pressure. Of an electroacoustic transducer or system used for sound reception, the root-mean-square sound pressure of a sinusoidal plane progressive wave, which, if propagated parallel to the principal axis of...
