Developing a Passive Vibration Absorber to Generate Traveling Waves in a Beam Conference Paper uri icon


  • Sound waves enter the outer ear and pass into the ear canal where the waves cause the eardrum to vibrate. Those acoustics are transmitted to the middle ear, and then pass through the innermost part of the ear, called the cochlea. The basilar membrane (BM), the main structural element of the cochlea, analyzes the waves propagating through it much like a biological Fourier analyzer. The waves travel from the base of the cochlea through the BM and get absorbed at the apex of the cochlea. These latter feature of the human auditory system is the inspiration to study waves propagating from one end of a beam to the other without reflections at the boundary.
