Figure 2. Sound amplitude correlates linearly with disc kinematics, (A) Sound pressure across 40 consecutive stimulations (black vertical lines) at 40 Hz (aqua, first stimulus; blue, last stimulus).(B) Peak sound pressure per stimulus (color-coded as in A) increases linearly with peak velocity (linear regression for three individuals: y = 5.2x-210.5, R2 = 0.96; y = 1.8x-35.1, R2 = 0.89; y = 7.8–136.3, R2 = 0.98) and peak acceleration (linear regression for three individuals: y = 14.3x-106.9, R2 = 0.91; y = 5.6x-6.1, R2 = 0.89; y = 24.3–75.5, R2 = 0.96). A minimal velocity and acceleration is required before sound is radiated Image published in: Kwong-Brown U et al. (2019) © 2019, Kwong-Brown et al.
