| Zusammenfassung | The measurement of the reduction of transmitted impact noise by floor coverings on heavy-weight floors is specified in ISO 140-8. Unfortunately the results obtained by this measuring method can not be used for the estimation of the improvement of the sound insulation of floor coverings on light-weight constructions. As this problem is well known, an ISO working group, ISO TC 43/SC2/WG22, was established to standardize another method to measure the reduction of transmitted impact noise by floor coverings on light-weight constructions. In connection with this topic, two main problems are to be solved. The first problem is to define a standard light-weight floor or a set of standard floors which would be a world wide representative construction. The second problem is related to excitation. Especially when light-weight floors are used in real buildings, the low-frequency transmission for a typical excitation like walking people or jumping children is quite strong. This typical behaviour of light-weight floors can not be simulated in the laboratory or in the field using a standard tapping machine as excitation source. Therefore Japanese acousticians proposed using a special rubber ballfor low-frequency measurements on light-weight floors. |
