4.28 equivalent speech recognition threshold sound pressure level. For a specified speech signal, type of transducer, and manner of signal presentation, the sound pressure level produced by a transducer in a specified acoustic coupler when the voltage applied to the transducer is that which produces sound pressure at the speech recognition threshold when the transducer is applied to an ear. Abbreviation, ESRTSPL; unit, decibel (dB).
