Sounding mechanism is numerically analyzed to elucidate physical processes in air-reed instruments. As an example, compressible large-eddy simulations (LES) are performed on both two and three dimensional ocarina. Since, among various acoustic instruments, ocarina is known as a combined system consisting of an edge-tone and a Helmholtz resonator, our analysis is mainly devoted to the resonant dynamics in the cavity. We focused on oscillation frequencies when we blow the instruments with various…

The aeroacoustics of a whistle have been investigated using a physical model based on the lattice Boltzmann methods (LBM) in two dimensions. The geometric data has been measured directly from a real

Chamber music: an unusual Helmholtz resonator for song amplification in a Neotropical bush-cricket (Orthoptera, Tettigoniidae)

It is shown that the pronotal chamber of a bush-cricket not only functions as a Helmholtz resonator owing to its intact morphology but also resonates at frequencies of the calling song on itself, making song production a three-resonator system.
