Input impedance of a cylinder zin (computed through Eq. (9) and Eq. (10)) of length L = 64 cm and radius R = 8 mm for different values of the acoustic RMS velocity at the open end. The value of cd has been set to 13/9, which corresponds to a radius of curvature of 0.3 mm, according to . From top to bottom, from left to right: modulus of the input impedance; relative gap between nonlinear and linear definition of zin; detail view on the first peak; detail view on the fourth peak.
