A drum produces sound via a vibrating membrane.

In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.<ref>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref>
