This paper is concerned with the acoustical analysis on sub-harmonic of glottal source in Mandarin tones. The methods used in this research are: 1) extracting glottal source of tones by inverse filtering; 2) analyzing subharmonic and spectrum tilt by FTT; 3) simulating the double peak pulse by 4 functions and describing the natures of them in both time and frequency domains. There are 3 conclusions: 1) the double peak pulse produce sub-harmonic in glottal source of Mandarin tones; 2) subharmonic influences the spectrum tilt; 3) the double peak pulse can be simulated and modeled mathematically.
