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.

Combining principles from computational fluid dynamics and acoustics, researchers have developed an analytical model that could simplify the process of designing Helmholtz resonators, a type of noise ...

Researchers deserve a round of applause for uncovering the science behind the acoustics produced from hand clapping that had not been clearly understood until recently. The daily gesture that people ...
