    Abstract

    Lightweight building constructions often suffer from insufficient sound insulation at low frequencies. In order to investigate the degree of the problems, a laboratory experiment has been carried out. Twenty test persons have been asked to evaluate series of typical noise from neighbours, ie, two kinds of airborne noise and two kinds of impact noise. The noise examples were presented with two different shapings of the frequency spectrum in order to stimulate either a heavy building construction or a typical lightweight construction. The noise examples were presented at four different levels and combined with two levels of background noise. The two frequency shapings were different in the frequency range 25-200 Hz, but identical at higher frequencies. Dose-response curves have been derived for annoyance, disturbance of concentration and subjective loudness. It has not been possible to analyze the influence of all parameters separately. One difference found between the airborne and the impact noise was that the annoyance due to airborne noise was significantly influenced by the level of background noise, whereas this was not the case for impact noise.
