Abstract
The purpose of this experiment was to determine the relative loudness of various spectral portions of speech. The loudness of each of seven third-octave bands of speech was determined for ten normal-hearing listeners who matched the loudness of an unfiltered speech sample to that of each of the filtered speech bands. The results suggested that the loudness of third-octave bands of speech is approximately constant from 500 through 3150 Hz, and perhaps through 4000 Hz.
