In a hydropower plant, screw pumps caused a noise level of 86 dB. This was happening due to the direct transmission of the forces generated during the pumping process to a water tank. This caused the entire facility to vibrate. The background noise was so loud that it was disturbing power plant employees. By inserting SL-450 and SL-840 SLAB pads between the screw head and the pump, the noise was reduced by 6.6 dB. Considering that a 10 dB reduction halves the volume, this is a big step forward in employee safety.
