A resonator is a device or part that vibrates with and amplifies Wave s. AUTOMOBILES A ''resonator'' is an independent part found in some Exhaust System s that works with the Muffler to reduce noise. A ''resonator chamber'' in automobiles is part of a muffler that attempts to force sound waves to "cancel each other out." {Link without Title} MUSICAL INSTRUMENTS Most Musical Instrument s include resonators for the sound of the instrument. In string instruments this is the body of the instrument. In many Keyboard Percussion instruments, below the centre of each note is a tube, which is a Cavity Resonator , that is referred to simply as the ''resonator''. The length of the tube varies according to the pitch of the note, with higher notes having shorter resonators. The tube is open at the top end and closed at the bottom end, creating a column of air which Resonates when the note is struck. This adds depth and volume to the note. In Camille Saint-Saëns ' '' Danse Macabre '', a Skeleton 's dance is depicted by a Xylophone . Since the instrument in Saint-Saëns' day did not have resonators, it is often performed with resonators removed (or covered). This makes sound of the instrument more brittle and Bone -like. The Vibrato effect of a Vibraphone is obtained by a mechanism which opens and shuts the resonators. Also, by itself, it may be referring to the resonator guitar, Dobro .
