WebA drum beat has a much lower frequency than a whistle, and a bullfrog call has a lower frequency than a cricket. The lower the frequency, the fewer the oscillations. High frequencies produce more oscillations. The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz. 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.
