| Technique |
---|
a | Select an appropriate location for noisy operations |
b | Enclose noisy operations/units |
c | Use vibration insulation of operations/units |
d | Use internal and external lining made of impact-absorbent material |
e | Use soundproofed buildings to shelter any noisy operations involving material transformation equipment |
f | Use noise protection walls and/or natural noise barriers |
g | Use outlet silencers to exhaust stacks |
h | Lag ducts and final blowers which are situated in soundproofed buildings |
i | Close doors and windows of covered areas |
j | Use sound insulation of machine buildings |
k | Use sound insulation of wall breaks, e.g. by installation of a sluice at the entrance point of a belt conveyor |
l | Install sound absorbers at air outlets, e.g. the clean gas outlet of dedusting units |
m | Reduce flow rates in ducts |
n | Use sound insulation of ducts |
o | Apply the decoupled arrangement of noise sources and potentially resonant components, e.g. of compressors and ducts |
p | Use silencers for filter fans |
q | Use soundproofed modules for technical devices (e.g. compressors) |
r | Use rubber shields for mills (avoiding the contact of metal against metal) |
s | Construct buildings or growing trees and bushes between the protected area and the noisy activity |
