DOI: 10.1121/1.4989301
Abstract: The simulation-based design of dynamically loaded and acoustically sensitive components essentially includes the determination of the radiated sound power. Regarding several simplifications different approaches based on the surface velocity can be applied, such as the… read more here.

DOI: 10.1121/1.5036029
Abstract: Vacuum-assisted toilet noise can be unsettling and even uncomfortable. One common way to reduce noise levels is to damp structural vibrations that radiate sound. We investigated whether constrained layer damping (CLD) treatments could reduce the… read more here.
