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 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.
