1 NOISE CONTROLS FOR PLANTS AND MILLS

2 SOURCE PATH RECEIVER

3 NOISE EXPOSURE CAN BE REDUCED BY:  APPLYING CONTROLS TO THE SOURCE (S)  BLOCKING THE PATH (S)  ENCLOSING THE RECEIVER  LIMITING THE EXPOSURE TIME

4 RESILIENT SCREEN DECKING

5 TREATED HOPPERS & CHUTES

6 RESILIENT CRUSHER LINER AND FEED PLATE

7 CHUTE LINERS

8 INSTALLATION OF CHUTE DAMS

9 VIBRATION ISOLATION MOUNTS

10 Barrier Concept Shadow Zone Diffracted Propagated Reflected Noise Source Barrier

11 ACOUSTICAL BLOCK WALLS

12 STRIP CURTAIN BARRIERS REQUIRE A 30 TO 50 % OVERLAP

13 TRACK MOUNTED PANELS

14 THE FOLLOWING DEVICES HELP TO REDUCE THE AMOUNT OF TIME SPENT IN HIGH NOISE AREAS THEREBY LOWERING NOISE EXPOSURE

15 CONVEYOR BELTING KEEPS MATERIAL ON THE SCREEN REDUCING CLEAN-UP TIME

16 SINGLE LUBE POINTS HELP REDUCE EXPOSURE TIME

17 REMOTE CCTV MONITORING

18 BEARING SENSORS

19 BIN LEVEL INDICATOR

20 MOST OF THESE DEVICES CAN BE MONITORED INSIDE AN OPERATOR’S CONTROL BOOTH

21 OPERATOR BOOTHS MUST PROVIDE ADEQUATE VISIBILITY

22 Maintain Your Noise Controls  Screen decking and chutes should be inspected and replaced or repaired during down time if possible  Barriers around mills and crushing equipment should be kept closed  Windows and doors of control booths should be tightly sealed  Remote sensors should be operational

23 Additional Resources

24 Your children can whisper to you now, Don’t make them shout at you in the future
