<p>A vibration attenuating member (27) includes at least a first layer (31) composed of a viscoelastic material having a Shore 00 durometer of less than 50 and a rebound percentage of less than 20. Preferably the vibration dampener also includes second and third layers, coterminous with the first layer (33, 35), which are composed of a foam material. The viscoelastic layer (31) may have a non-uniform shape, such as precurved (Fig. 1), tapered (Fig. 5), or the like. The viscoelastic material may be creased (51, 53) to facilitate bending. The member (27) has a transmissibility no greater than 1.0 in the range of from 31.5 to 200 Hz, and a transmissibility of no more than 0.6 in the range of from 200 Hz to 1250 Hz (Fig. 8). The vibration attenuating member (27) may form a glove, a glove liner, a portion of a glove liner, a portion of a glove, a sports glove, a wrap for a tool, or be used in some other application where vibration attenuation is desirable.</p> |
