HIGHLIGHTS
- who: Jean Boulvert from the Laboratoire have published the article: Compact resonant systems for perfect and broadband sound absorption in wide waveguides in transmission problems, in the Journal: Scientific Reports Scientific Reports
- what: The authors focus on the design of compact FMAA and more particularly on the number of HRs.
- how: The sample was tested in a in-house impedance tu00ad ube9 of internal cross section W u00d7 H=14.8 u00d7 15 cm 2 and terminated by an anechoic termination.
