TABLE II.

Statistical quantities computed from current simulation compared to typical ranges reported by previous studies. F0 is the fundamental frequency; Qmax and Qmean are the peak and mean glottal flow rate, respectively; τ0 is the open quotient, defined asτ0=T0/T, where T0 is the duration of the glottal open phase(computed based on the glottal motion) and T is the cycle period; τs is the skewing quotient, defined as τs=Tp/Tn where Tp is the duration of the flow increasing phase and Tn is the duration of the flow decreasing phase. Trans-glottal pressure was 1.2 kPa.

  Computed value Typical range
F0 (Hz) 194.7 65–260 (Zemlin, 1988)
Qmax (ml/s) 336.53 200–580 (Hertegard et al., 1992)
Qmean (ml/s) 147.07 110–220 (Zemlin, 1988)
τ0 0.60 0.4–0.7 (Titze, 2000)
τs 1.28 1.1–3.4 (Ishizaka and Flanagan, 1972; Lamar et al., 2003; Duncan et al., 2006)
