A study of an acoustical wave-guide with longitudinal partitions using the theory of the multi-degree-of-freedom systems

A system of nonlinear equations for the normal frequencies and the eigenfunctions of a cross section of an acoustic wave-guide with two longitudinal elastic partitions, linked with a raw of springs has been derived in the papers [1–2]. Such acoustic system supposed to be a model of the microstructure of the media canal of the mammalian cochlea. A numerical solution of these equations and a graphical analysis are undertaken in the present paper.
