WebIn speech, the resonant frequencies of the vocal tract (that is the frequencies that resonate the loudest) are called formants. We can see them as the peaks in a spectrum. With vowels, the frequencies of the formants determine which vowel you hear and, in general, are responsible for the differences in quality among different periodic sounds.

WebA Helmholtz resonator is simply a box with a port on its front side to couple the enclosed volume of the airspace in the box to the air in the room.
