There is a growing tendency to use lightweight constructions in the building industry. One unwanted side effect of this tendency is poor sound insulation at low frequencies. The purpose of this investigation has been to examine the subjective effects of the resulting increase of low frequency noise from neighbours in dwellings using listening tests. The results of the experiments confirm that noise from neighbours transmitted through light constructions is indeed rated more annoying than noise transmitted through heavier constructions.
