It began more than twenty years ago as a com-prehensive study directed toward analyzing and describingspeech and hearing just as electrical circuits and telephone in-struments are analyzed and described. Many advantageswould accrue if the characteristics of the voice and ear couldbe given consideration in the engineering and design of thetelephone.
