Abstract
A previously reported study by Gibson (1970) found a less categorical limitation in the analysis of harmonically complex tones than that stated by Plomp and Mimpen in 1968. Meanwhile Duifhuis (1970) has indicated a general capability to hear partials as high as the fifteenth to the twentieth when all are at a normalized level of 30 dB. Our further investigation of peripheral capabilities establishes that, in binaural listening to a two-way loudspeaker in a music room, experienced musicians can consistently duplicate the frequency of any intermittent partial as high as the eleventh for 31.25-Hz tones, the twelfth for 44-Hz tones, the fifteenth for 62.5-Hz tones, the fourteenth for 125-Hz tones, the eleventh for 250-Hz tones, the eighth for 500-Hz tones, the fifth for 1000-Hz tones, and the third for 2000-Hz tones. In binaural listening via earphones to a similar complex tone having the same phase in both ears, the capability may be reduced 10% to 25%. [Research sponsored by North Texas State University.]
