Theoretical analysis and measurement of sound transmission loss in louver elements with a sound attenuating function using a Helmholtz resonator array

This paper discusses a noise reduction structure with a thin Helmholtz resonator array integrated in louver elements. Using theoretical analysis, we derived the propagation constant and characteristic acoustic impedance with consideration for sound wave attenuation in the clearance between two plane...
