Improving sound absorption through nonlinear active electroacoustic resonators
Xinxin Guo, Romain Fleury, Hervé Lissek
Absorbing airborne noise at frequencies below 300 Hz is a particularly vexing problem due to the absence of natural sound absorbing materials at these frequencies. The prevailing s…

Constant-pressure sound waves in non-Hermitian disordered media
Etienne Rivet, Andre Brandstötter, Konstantinos G. Makris +3
When waves impinge on a disordered material they are back-scattered and form a highly complex interference pattern. Suppressing any such distortions in the free propagation of a wa…

Joint Estimation of Room Geometry and Modes with Compressed Sensing
Helena Peić Tukuljac, Thach Pham Vu, Hervé Lissek +1
Acoustical behavior of a room for a given position of microphone and sound source is usually described using the room impulse response. If we rely on the standard uniform sampling,…
