How does helmholtz resonator work
WebThe Helmholtz resonator is comparable to a classical mass–spring system, which has a resonance angular frequency equal to the square root of the ratio between the mass and the spring constant . The mass of the nozzle or restriction is equal to , with or the cross-section and or the length of the nozzle or restriction. WebA Helmholtz resonator consists of a neck that leads into a larger volume. One example of this type of resonator is a glass bottle. When blown into, the bottle resonates at a very specific frequency. The fundamental frequency depends on the cross-sectional area and length of the neck, as well as the volume of the cavity.
