Quantified effects of stiffness constant ( ) on amplitude and frequency of oscillations. (a) The graph shows the effect of variations in stiffness constant on the amplitude of oscillations. The monotonically decreasing nature of the graph suggests that the stiffer the membrane, the smaller the amplitude. (b) The graph shows the effect of variations in stiffness constant on the frequency of oscillations with a maximum at .
