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.
