A compound microperforated panel backed by a panel-type resonator with a Helmholtz neck and multi-frequency resonators to improve bandwidth and low frequency sound absorption Open
The present study is aimed to develop a compact sound absorber structure that can simultaneously improve low frequency sound absorption performance and broaden the half-absorption bandwidth of a microperforated panel (MPP)-type structure. …

On improving low-frequency sound absorption using a compound microperforated panel backed by a panel-type resonator with tuned multi-frequency resonators Open
The present work is aimed to broaden the half-absorption bandwidth and improve low frequency sound absorption of a microperforated panel (MPP) by investigating the effects of tuned multi-frequency resonators attached to a flexible panel (i…
