Health and research
The Mine Health and Safety Council works closely together with various South African universities, companies, and governmental establishments to make sure all hearing conservation program goals are met.
The first goal to tackle was to decrease deterioration in the hearing of mining workers to less than 10 percent. This is in part achieved by ensuring that all mining equipment does not exceed a sound pressure level of 110 decibels (dB) anywhere in the workplace. But sound levels in mining equipment and machines are typically high, which meant that this was a tough target to hit.
University of Pretoria
The University of Pretoria was tasked to tackle the problem. With the aid of Siemens Simcenter testing solutions and the Simcenter Sound Camera for sound source localization, the University of Pretoria measured noise levels and pinpointed the problem areas in mining machines. This helped identify what needed to be adjusted to not exceed the 110dB threshold.
The advanced sound source localization solution significantly reduced testing and measuring time, reduced costs, and helped mining companies achieve safer work environments faster and more efficiently.
