This amazing feature of the inner ear lead us to study the dynamics of a uniform beam connected to a spring-damper system as a passive absorber, in order to understand some of the observed phenomenological behaviors of the basilar membrane. The location of the spring-damper system divides the beam into two dynamic regions: one which exhibits non-reflecting traveling waves and the other with standing waves. In this work, traveling waves co-existing with standing waves in the two regions of the structure and are studied analytically, numerically, and experimentally. The results of this work are the first steps in leading us to new applications of the linear vibration absorber and a possible explanation of the functionality of the helicotrema in the cochlea. |
