STUDY OF THE SOUND PROOFING OF THE MACHINES USED IN THE CONCRETE INDUSTRY

ETUDE DE L'INSONORISATION DES MACHINES DE FABRICATION UTILISEES DANS L'INDUSTRIE DU BETON 711L CONSIDERED. AN EXAMPLE IS GIVEN OF THE USE OF CAPSULES IN A 711O TABLES AND MACHINS. /TRRL/

This study begins with an investigation on vibrating tables for which various possible sound proofing techniques (sound proofing at the source of the noise, sound proofing by encapsulation) are examined. The sound was measured in the vicinity of a vibrating table, the characteristics of which varied (vibration, suspension, stiffening, mould clamping) and which was later fitted with capsules of different kinds of material. The principle of sound proofing is studied in detail together with the origins and characteristics of the noise emitted. The possibilities of reducing noise at source are examined, and methods of encapsulation are considered. An example is given of the use of capsules in A factory. In conclusion is found a study of vibration systems, that is the basis for the design of new vibrating tables and machines.
