The plot compares the blue structural wavelength with the red acoustic wavelength. The joint-acceptance factor (J1d) ranges from 0 to 1.27: J1d = 0 indicates no coupling.

In this example, setting the structural frequency to 135 Hz yields a 1D joint-acceptance of 1.0.  Full coupling.  At 135 Hz change the number of half waves to 4 and the joint-acceptance goes to 0. , canceling the coupling completely.
