    mills, screens and many other items of mining and mineral processing plant are inherently noisy, and most require some form of operator attendance. Noise-induced hearing loss entails substantial economic costs. As well as the financial cost, there is a reduction in quality of life for a person with severely impaired hearing. Mining companies recognise noise as a hazard requiring control, and
