Acoustic metamaterial design for noise reduction in vacuum cleaner

In this study, we investigate the acoustic metamaterial (AMM) design for flow noise reduction when using a vacuum cleaner. The AMM was based on the principle of Helmholtz resonators, and metamaterial design variables were defined to reduce noise to approximately 1.5 and 2.5 kHz bands. An acoustic si...
