Abstract : An experiment is carried out to examine to what extent the loudness of voiced-unvoiced speech sounds is affected by the harmonic or continuous nature of their spectrum. Stimuli are synthesized by a 10 pole numeric filter simulating the transfer function of a vowel; this filter is excited either by white noise (lowpass filtered at 150 Hz, 6 dB/oct) or by a square wave (Fo=150 Hz). The RMS energy and duration of the stimuli are alike. The subjects perform the loudness equalization task using the adjustment method. The effect prooved to be no significant; consequently no relation was found between the loudness and the specific nature of the spectrum.
