Sound attenuation is a damping of sound, an interruption that diminishes the volume and quality of the sound wave. This reduces how far sound travels.

Why do we need sound attenuation?

By reducing the sound output of mining machinery, several benefits can be achieved:

• The machinery can work closer to the sound monitors on the mine sites boundaries.

• The reduction in mining noise keeps communities onside.

• Increased mining operating times

• Operator safety

How does sound attenuation work?

Sound attenuation can be achieved by combining these principles:

• Blocking sound frequencies

• Absorbing the sound

• Isolating vibrations

• Reactive (noise cancelling frequencies)
