Commission Implementing Decision of 26 March 2013 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the production of cement, lime and magnesium oxide (notified under document C(2013) 1728) (Text with EEA relevance) (2013/163/EU)

1.1.2 Noise
2.In order to reduce/minimise noise emissions during the manufacturing processes for cement, lime and magnesium oxide, BAT is to use a combination of the following techniques:
Technique
aSelect an appropriate location for noisy operations
bEnclose noisy operations/units
cUse vibration insulation of operations/units
dUse internal and external lining made of impact-absorbent material
eUse soundproofed buildings to shelter any noisy operations involving material transformation equipment
fUse noise protection walls and/or natural noise barriers
gUse outlet silencers to exhaust stacks
hLag ducts and final blowers which are situated in soundproofed buildings
iClose doors and windows of covered areas
jUse sound insulation of machine buildings
kUse sound insulation of wall breaks, e.g. by installation of a sluice at the entrance point of a belt conveyor
lInstall sound absorbers at air outlets, e.g. the clean gas outlet of dedusting units
mReduce flow rates in ducts
nUse sound insulation of ducts
oApply the decoupled arrangement of noise sources and potentially resonant components, e.g. of compressors and ducts
pUse silencers for filter fans
qUse soundproofed modules for technical devices (e.g. compressors)
rUse rubber shields for mills (avoiding the contact of metal against metal)
sConstruct buildings or growing trees and bushes between the protected area and the noisy activity
