BAT is to reduce noise emissions from relevant sources in the iron and steel manufacturing processes by using one or more of the following techniques depending on and according to local conditions:

• implementation of a noise-reduction strategy

• enclosure of the noisy operations/units

• vibration insulation of operations/units

• internal and external lining made of impact-absorbent material

• soundproofing buildings to shelter any noisy operations involving material transformation equipment

• building noise protection walls, e.g. the construction of buildings or natural barriers, such as growing trees and bushes between the protected area and the noisy activity

• outlet silencers on exhaust stacks

• lagging ducts and final blowers which are situated in soundproof buildings

• closing doors and windows of covered areas.
