Abstract
An archery bow has at least one dampener to reduce noise and vibration of the bow in use. Desirably, at least one dampener, and preferably a plurality of individual dampeners may be disposed in the area of the connection of a limb to a riser or handle portion of the bow to reduce vibrations transferred to the riser by the limb. Additionally, the archery bow preferably has a cam adapted to receive a dampener to reduce the noise and vibration passing between the cam and the limb. Any number of dampeners may be used in combination, or the dampeners may be used separately as desired.

An archery bow, comprising:
- a riser having spaced apart ends;
- a pair of limbs each having a first end attached to a separate one of the ends of the riser and a free end spaced from the riser;
- a dampener received between the riser and the first end of each limb to reduce vibration of the bow in use;
- and
- the dampener has a pair of opposed faces defining a height of the dampener between them and in assembly of the limb to the riser the dampener is compressed in height between 10% to 50% of its height before compression.
