Title Noise reduction measures in the cement industry
Original title Massnahmen zur Lńrmminderung in der Betonindustrie [in German]

Abstract When shaping machines are used for the manufacturing of paving blocks, concrete slabs and pipes, noise reduction at the source by design modifications of the machinery is not sufficient. Noise levels still amount to between 110 and 125dB. Only acoustic enclosures bring noise exposure down to levels below 85dB(A). Examples of efficient enclosures are presented.
