How does a whistle produce sound
Whistles that generate sound through fluctuations of momentum or stress and strain of a force exerted on the surrounding medium are called dipole-like sources. The figure on the right is an example of a small rigid sphere that is moving back and forth in a given direction. This results in a non-uniform sound field. See more A whistle is a device that makes sound from forced air. The physical theory of the sound-making process is an example of the application of fluid dynamics or hydrodynamics and aerodynamics. By understanding the … See more Aerodynamic whistles rely on the instability of flows and feedback that enhances the instability. There are several ways that feedback … See more Feedback in whistles is nonlinear mechanics or chaos. Because of the nonlinearity, it is possible to have more than one frequency at a given flow rate. The difference depends on whether the flow rate is achieved by increasing the flow or by … See more Whistles come in all shapes and sizes, but their operation can be unified through the concepts of dynamic and geometric similarity using See more Wilson, et al., in their study of human whistling (see below), pointed out the importance of including the symmetry or asymmetry of the unstable flow in addition to the feedback classes listed below. Because of the close relationship of flow symmetry to the … See more Flow instability is the engine for whistles. It converts steady energy to time-dependent energy. An example is shown in the figure on the right with a water jet. The laminar two-dimensional jet amplifies small disturbances at the … See more In these whistles, the flow instability is symmetric, often resulting in periodic ring vortices, and the sound generation is associated with … See more WebThe sound wave come out of the hole, get dispersed strongly, and finally reaches our ears.
