Applications of Noise Control in the Mining Industry
Noise SourceNoise PathNoise ReceiverConclusionThere are three basic approaches to protecting the individual worker from hazardous noise exposure. First, we can address the source of the noise directly. This can be implemented at a number of different stages throughout the mining lifecycle. Noise should be a consideration early on and throughout the mining process, which means that it is imperative to ensure effective, considerate operational and administrative practices in tSee more on noisesolutions
