Concert Hall Acoustics: Art and Science

Use of vibration isolation to reduce noise in concert halls

Anti-vibration mounts are used to prevent vibrations entering the auditoria and creating noise. The right diagram shows the construction of the Bridgewater Hall in Manchester. In the bottom centre of the picture, the green anti-vibration spring can be seen purched on top of one of the piles. This may be clearer in the diagram below right.

This units are springs to prevent vibration in the piles being transmitted into the building. They act in a similar way to how springs are used in car suspension to prevent bumps in the road being transmitted into the vehicle. A close up of a unit used in another hall is shown below.
