13. Textile Noise Pollution Control
Muhammad Fahad Ansari 12IEEM14

14. Textile Noise Pollution Control
 The textile industrial noise may be avoided by keeping the industries
far from residential areas
 In spinning noise can be reduced by elastomeric spindle elastomeric
spindles and elastomeric ring holders.
 Proper maintenance and lubrication of machine parts
 Replacement of metal parts with rubber or nylon coated material
instead of metal.
 Tightening of loose parts to avoid vibration
Muhammad Fahad Ansari 12IEEM14

15. Textile Noise Pollution Control
 Use anti vibration rubber sheet
 Use vibration isolators to prevent noise transmitted through the base
of machine
 Use sound absorbers
 Use disposable ear corded ear plugs
