The study of [[sound]] and vibration are closely related. Sound, or "pressure waves", are generated by vibrating [[structures]] (e.g. [[vocal cords]]); these pressure waves can also induce the vibration of structures (e.g. [[ear drum]]). Hence, when trying to reduce noise it is often a problem in trying to reduce vibration.
