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 | |
|---|---|
| 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 |
