Broadband Sound Absorption of Subwavelength Porous Meta-Liner

This work proposes a subwavelength porous meta-liner with broadband sound absorption from 900 to 1,200 Hz.The meta-liner consists of four subunits, which are made up of porous material Drill Bit and hollow coiling slit embedded in it.Each subunit is designed by adjusting the length of its coiling slit to achieve resonance in the target frequency an
