An apparatus and method are provided for maximizing the punch of a bass kick-drum and simultaneously minimizing the .pi.nging of the drum, comp.pi.sing an insert having a cylind.pi.cally shaped body adapted to be slid into a conventional circular opening in the resonant membrane of the drum The insert is sized to tower the fundamental frequency of the resonant membrane, to increase the amplitude of the fundamental resonant frequency, and to simultaneously dampen the vibration of the resonant membrane The .pi.nging of the drum is minimized by quickly dampening the vibration of the resonant membrane wherein the increased dampening is caused by the weight and shape of the insert A method of optimizing the sound of the drum is provided whereby the sizing of the insert is adjusted to maximize the punch and minimize the nng of the resonant membrane

La présente invention concerne un appareil et un procédé de maximisation de la force d'impact d'une grosse caisse et de minimisation simultanée de la résonance de la grosse caisse ; il s'agit d'un insert ayant un corps de forme cylindrique adapté pour être glissé dans une ouverture circulaire conventionnelle dans la membrane résonante de la caisse. L'insert est de taille à dominer la fréquence fondamentale de la membrane résonante, afin d'augmenter son amplitude et d'amortir simultanément la vibration de la membrane résonante. La résonance de la caisse est minimisée en amortissant rapidement la vibration de la membrane résonante : l'augmentation de l'amortissement est causée par le poids et par la forme de l'insert. Un procédé d'optimisation du son de la caisse est proposé dans lequel la dimension de l'insert est ajustée pour maximiser la force d'impact et minimiser la résonance de la membrane résonante.
