DESIGN AND EVALUATION OF AN IMPACT NOISE LABORATORY

An acoustic laboratory has been constructed in order to measure sound transmission through floors. It has been erected inside an existing building. Apart from the costs being considerably less than if a new building had been constructed, this has meant that several other advantages have been obtained. The design and location of the laboratory have been partially governed by activities already existing in the building. This article presents the construction from the point of view of building technique and of acoustics. In an effort to eliminate flank transmission in the frequency range 100-3150 Hz the construction has been dimensioned with vibration dampers having a natural frequency of 10 Hz. For the same reason and in order to increase the sound insulation the walls and ceiling have been lined with radiation reducing material. Comparative calculations and measurements have been carried out which show how the results have been affected by this procedure. The radiated effect from the various surfaces is shown in the form of graphs.
