The report presents an overview of the acoustic problems related
to light-weight timber floors as they are typically found in
modern buildings in the Nordic countries. After a review of
recently published literature on the topic, a number of current
projects in the Nordic countries are presented. 17 examples of
current timber floor constructions are described and measuring
results are given as well as subjective judgements of the acoustic
quality.The relation between annoyance and impact sound level is
analysed on the basis of a number of field investigations found in
the literature. It is concluded that the frequency range for
measurements should be extended below 100 Hz, at least down to 50
Hz and preferably down to 20 Hz. It is found that deflection and
vibration of the floor are often evaluated as a problem in timber
floor constructions.
