  • Noise Pollution and Its Control in Mining

     · The noise level with the deep hole blasting and the pressure wave at wide range of frequency was transmitted in the atmosphere. Loss of hearing and damage to the surface structures were the result of the impulse noise and air over pressure. The noise level in the draft proposal for coal mining area was recommended below 75 dBA during 6 AM to 9

  • Evaluation and Modelling of Environmental Noise Pollution

    A palm oil processing mill noise has negative environmental impact. The distances at which its adverse effects shall cover have to be professionally determined. This work therefore presents evaluation and modelling of environmental noise pollution from a palm oil processing mill with a maximum noise level of (110.640.69) dBA.
