The vibrations emitted by a source of sound can be compared with the ripples or waves created when a stone is thrown into calm water.
It is, however, directly comparable only as far as the concentric shape of propagation is concerned. Looked at in detail, the vibrations are in fact very different.

Information and ideas:
Students can do the experiment themselves on an excursion out of school.
