Generating Anechoic Traveling Wave in Beams with Various Boundary Conditions Conference Paper uri icon


  • The basilar membrane (BM) is one of the prominent structural members of the inner ear which transports acoustic signals, received by the tympanic membrane in the middle ear, as structural waves to the hair cells. Another characteristic of the BM is its ability to absorb the energy of the structural waves at the apex end of the cochlea. As a result of this biological mechanism, the acoustic energy does not reflect at its boundary and as a result does not resonate back into the BM. This is a key feature of the BM, in particular effects by the helicotrema, that enables humans to hear and comprehend a string of continuous acoustic signals without any overlap. The present work is the result of the inspiration to develop waves propagating in engineering structures with such anechoic characteristics.
