01 Below 65 db Tolerable
02 80 db Annoying / irritating
03 88 db Hearing Disorder if prolonged exposure
04 110 db Discomfort & may cause hearing loss
05 135 db and above Painful

Textile Noise Pollution Control
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
Textile Noise Pollution Control
By: Muhammad Fahad Ansari 12IEEM14
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
