TIL that a seashell can form a Helmholtz resonator with low Q factor, by amplifying many frequencies, resulting in "rushing sounds of the sea FX
Helmholtz resonators are important for me in PA Audio Engineering, studio Engineering and pure Physics
Subwoofers have Helmholtz resonators. We use Helmholtz resonators to remove standing waves in acoustic ENV:
In every and all stringed instruments, response curves of instruments consists of a series of Helmholtz resonance modes in association with the size and shape of the resonance cavity including vibration damping from absorption by the resonance cavity material
