A round of applause, please: Scientists have finally figured out what’s behind the sound of clapping. The research pinpoints a mechanism called a Helmholtz resonator — the same acoustic concept that ...

The design halves the width of material needed to absorb low-frequency noise, making it practical for real-world applications ...

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.

Hand clapping is ubiquitous behavior for humans across time and cultures, serving many different purposes: to signify approval with applause, for instance, or to keep time to music. Acousticians often ...

In either the 1850s or 1860s, German physicist Hermann von Helmholz created a device to analyze sound. In 2005, that same sort of device made its way into the airbox of the new 3.8-liter flat-six of ...
