Horton Archery Mini Stripes Sound Stoppers - Pair is perfect for the bow hunter looking to kill the noise! Lost energy manifests itself as vibration which can loosen components, damage accessories and cause noise. To reduce this unwanted vibration and noise, many companies offer obtrusive or stangely-shaped objects made of rubber or neoprene. However, this one dimensional rubber captures energy that is in the same dimensional plane relative to that of the molecular structure of the material. Therefore, noise and vibration dampeners made of rubber and neoprene do not absorb all of the energy, regardless of the object's shape.
