equivalent noise pressure

[i′kwiv·ə·lənt ′nȯiz ‚presh·ər] (engineering acoustics) In an electroacoustic transducer or sound reception system, the root-mean-square sound pressure of a sinusoidal plane progressive wave, which when propagated parallel to the primary axis of the transducer, produces an open-circuit signal voltage equivalent to the root-mean-square of the inherent open-circuit noise voltage of the transducer in a transmission band with a bandwidth of l hertz and centered on the frequency of the plane sound wave. Also known as inherent noise pressure.
