Abstract
A percussion instrument dampening pad (PIDP) that is designed to be attached to the vibrating surface of a drumhead, a drum, a cymbal or the like. The PIDP functions by reducing unwanted vibrations and overtones that occur when the drumhead or cymbal is struck. The PIDP is comprised of at least one composite upper section, a first vibration absorbent layer preferably comprised of polyurethane puron foam, and a second vibration absorbent layer preferably comprised of butyl rubber that is in contact with the vibrating surface of the drumhead, drum or the cymbal. The composite upper section is further comprised of a metallized layer, a fabric layer and an adhesive layer. The PIDP also includes indicia and a removable liner that is removed prior to attaching the exposed butyl rubber to the surface of a drumhead or the like.
