(Gauss Centre for Supercomputing) Combining principles from computational fluid dynamics and acoustics, researchers at the TU Berlin have developed an analytical model that could simplify the process of designing Helmholtz resonators, a type of noise cancelling structure used in airplanes, ships, and ventilation systems. The model can predict a potential Helmholtz cavity's sound spectrum as turbulent air flows over it, and could potentially be used to tune Helmholtz resonators to cancel or avoid any frequency of interest.
