  • HSE - Noise: How do I reduce noise?

    Use barriers and screens to block the direct path of sound. Position noise sources further away from workers. Design and lay out the workplace for low noise emission, eg: Use absorptive materials within the building to reduce reflected sound, eg open cell foam or mineral wool. Keep noisy machinery and processes away from quieter areas.

  • Excavators: More than just a digger - KHL Group

    Aug 02, 2017 · This excavator has achieved a fuel saving of up to 20% compared to the JZ140, in part due to the use of larger 130 litre/min hydraulic pumps that maintain the overall maximum pump flow while allowing the engine speed to be reduced from 2,050 rpm to 1,800 rpm. This has the added benefit of reducing internal noise levels to 70 dB.
