materials fig4 also illustrates a composite type damping segment however the embodiment illustrated in fig4 utilizes two rigid non elastic layers 21 and 23 sandwiching an elastic layer 25 therebetween thus shearing forces can dissipate vibratory force provide damping at two rather than one interface the elastic layer as discussed above provides additional damping as well as some sound absorption functions a layer of non hardening pressure sensitive adhesive 27 is applied to rigid layer 23 for segment retention as discussed above the present invention also discloses a mapped cymbal especially configured and adapted for accurate and precise placement u2014 and replacement u2014 of sound absorption and vibration damping segments thereupon more specifically the mapped and tuneable cymbal of the present invention includes an upper surface a lower surface and a circumferential edge at least one of the lower surface and upper surface of the cymbal is marked with specifically identified tuning locations enabling the precise placement of either sound absorption or vibration damping segments of the present invention or combinations thereof in a first preferred embodiment of the mapped cymbal of the present invention at least one surface of the tuneable cymbal includes markings outlining the aforementioned segment shapes however additional predetermined shapes may be included in said mapping if corresponding segment shapes are configured and utilized the mapping outlines including round square rectangular elongated and circumferential outlines include therewithin numbers letters or other indicia representative of the location thereof thus sound absorbing and or vibration damping segments may.
