Abstract: A two ply, synthetic drumhead for use in hand drums is created by using a laser to precisely remove excess material in the form of V-shaped notches from the peripheral portion of each layer disc of drumhead material prior to bonding and forming the drumhead sheet. After removal of the excess material, each layer disc has a peripheral edge consisting of equal size finger-like projections alternating with V-shaped notches. The layers are positioned so that the notches of one layer are covered by the projections of the other layer, producing a finished drumhead having a uniform exterior appearance and feel. The drumhead is tuned to duplicate the sound of a natural skin drumhead by positioning a damping element between the layer discs prior to bonding and assembly.
