Figure 5

Aerodynamic and acoustic parameters immediately following phonation onset compared to those at onset. From top to bottom: ΔFlow = Flow immediately after onset – PTFonset; ΔSPL = sound pressure level immediately after onset – sound pressure level at onset; Pressure Wave Amplitude = amplitude of subglottal pressure wave immediately after onset; ΔPressure = mean subglottal pressure immediately after onset – PTPonset. Alternating groups of solid bars and open bars distinguish data from different subjects as labeled at the bottom of the graph. ΔSPL data were only collected for the 4 larynges shown.
