Researchers describe an acoustic meta-surface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation.

A new study introduces the concept of 'modal dominance' to describe energy confinement through frequency-based interactions instead of mechanical links. (Nanowerk News) Mode-localized ...

Resonators are devices used to amplify wavelengths,they exist in many devices and come in many forms. Resonators commonly exist in science as mechanical, acoustic (sound), optical (light), microwave ...

Abstract: Quartz crystals are mechanical resonators with piezoelectric properties. The piezoelectric properties (electric potential across the crystal is proportional to mechanical deformation) allow ...
