Calculation of airborne and impact sound insulation between dwellings
article
Some years ago a model was described for the calculation of the weighted airborne sound insulation between dwellings. Further work has been done since in order to increase the applicability of this model, including the extension to octave band calculations. Besides airborne sound, impact sound is also of importance. Therefore the calculation model has also been extended to impact sound insulation. These calculations are based largely on the same input data as for airborne sound. A new quantity however is the floor admittance. For homogeneous floors an existing model for the calculation of the admittance could be applied. For typical (Dutch) floor constructions consisting of concrete beams and plates a model for the admittance has been developed, based on admittance measurements in situ. Some examples are given of calculated and measured airborne and impact sound insulation.
