An Acoustic Frequency Selective Curtain Composed of Thicker and Thinner Membranes and Periodically Connected Elastic Pillars

This paper proposes an acoustic frequency selective curtain composed of two membranes and periodically connected elastic pillars. This new architecture, which was inspired by the structure of sensory hair cells in human auditory system, generates a pass band at a certain frequency, and can be used as a curtain which allows only a specific sound pass through.
