摘要:
A reduced volume drumhead has a layer of porous material and a ring of compressible material. The ring of compressible material is fixed to the underside of the layer of porous material in a substantially centered or coaxial position with the porous material stretched across a hoop in tension. The ring may be formed of a foam or similar material with compressibility and stretchability under tension and defines an open central area of the drumhead for striking. The ring may be formed of segments and thus include one or more circumferential breaks with spacing. The drumhead provides natural tonal characteristics and has a natural feel when struck.
