This is the continuation of actions started in 2015, when 7m high sound-absorbing barriers had been built along the traffic routes in Miedzianka plant to reduce the noise emitted by transport, trucks, trains and loaders.
In order to further decrease the noise emission, special octagonal noise reducers have been installed on the upper edge of the barriers.

Octagonal noise reducers allow to lower the
sound level by absorbing diffracted sound waves. The covering of the
reducer is made from a bent perforated aluminum plate. The inner part
consists of spiral pipes made from galvanized aluminum sheet.
Sound-absorbing material is the mineral wool plate.
The second step was replacing the old gate to the stock yards. The gate was made of steel elements and didn’t provide enough protection against noise. Therefore Nordkalk decided to install a new gate with acoustic panels.
