Sound absorption performance of the acoustic absorber fabricated by compression and microperforation of the porous metal
Novel acoustic absorbers were fabricated by the compression and microperforation of the porous metal, which aimed to develop practical acoustic absorbers for the noise reduction. Sound absorbing coefficients of the five investigated acoustic absorbers were measured by the AWA6128A detector according...
