PP 1897: Calm, smooth and smart - novel approaches for influencing vibrations by means of deliberately introduced dissipation
Abstract:
Noise radiation of plate structures is a common problem with the design of machines in mechanical engineering. Noise can be reduced bydesigning passive damping measures. One of this measures can be the application of an ‘acoustic black hole’ (ABH). The ABH is a targetedadaptation of the thickness of the plate-like structures to direct the acoustically critical bending waves to a certain region -- the acoustic blackhole. There, an applied damping material can dissipate the vibration energy very e...     »
