Annotation
The effect of the sound pressure amplitude in the channel on the acoustic impedance of the transverse septum with an aperture is studied. The dependences of the imaginary and real parts of the impedance for different ratios of the hole diameter to the channel diameter in nonlinear modes are obtained.
