HIGHLIGHTS
- who: Vivien Denis et al. from the Messian, Le Mans, France have published the research work: Improvement of the acoustic black hole effect by using energy transfer due to geometric nonlinearity, in the Journal: (JOURNAL)
- what: This study shows that both damping and nonlinear e ect can be decoupled as the additional length (or the length of the ABH region) and the length (or the material characteristics) of the 17 damping layer can be independently adjusted to nd an optimal behavior, depending of the context. This study is devoted to the nonlinear e ects in . . .
