Compact resonant systems for perfect and broadband sound absorption in wide waveguides in transmission problems

Boulvert, Jean; Gabard, Gwenael; Romero-García, Vicente; Groby, Jean-Philippe (Nature Publishing Group, 2022-06-15)

[EN] This work deals with wave absorption in reciprocal asymmetric scattering problem by addressing the acoustic problem of compact absorbers for perfect unidirectional absorption, flush mounted to the walls of wide ducts. ...
Perfect, broadband, and sub-wavelength absorption with asymmetric absorbers: Realization for duct acoustics with 3D printed porous resonators

Boulvert, Jean; Humbert, Thomas; Romero-García, Vicente; Gabard, Gwenael; Fotsing, Edith Roland; Ross, Annie; Mardjono, Jacky; Groby, Jean Philippe (Elsevier, 2022-04-14)

[EN] This article explores, theoretically and experimentally, asymmetric absorbers made of detuned and folded quarter wavelength resonators filled with air or porous materials. When used as acoustic lining in ducts, their ...
