Abstract

For areas with restricted access such as box sections (3), pipes and wall sections etc, vibration damping poses a problem as it may be difficult or impossible to apply conventional damping such as tiles and the use of lead shot or sand presents a weight problem. By using a vibration damping material consisting of a plurality of viscoelastic spheres (1) the ease of application is improved and effective damping achieved especially if a high density filler is included in the viscoelastic material. Application of viscoelastic spheres can be made to damp the vibration of any structure where the viscoelastic spheres can be suitably confined.
