Ultra-thin low frequency perfect sound absorber with high ratio of active area [PDF]
, 2018 A concept of ultra-thin low frequency perfect sound absorber is proposed and demonstrated experimentally. To minimize non-linear effects, an high ratio of active area to total area is used to avoid large localized amplitudes.
