The Finnish Association of Civil
Engineers published the first Finnish sound insulation requirements of
buildings in 1967. The drawing up of the requirements was first time
suggested in 1948, and several drafts
were done during the 1950’s and 1960’s. At the same time, there was no
chair for building acoustics in
Finland, neither a
modern acoustical laboratory. Thus, the
possibilities to do domestic research were quite
limited and different organizations and researchers had to get information
of building acoustics from other
countries.
In Finland, the German measurement
methods of sound insulation were adopted and used through the 1950’s
and 1960’s. Since the end of the 1940’s, the Finnish engineers had
close contacts with their colleagues in the
Scandinavian
countries. In the end of the 1950’s, the Nordic
countries tried to make a common draft for
sound insulation requirements, but no consensus dealing with the
measurement methods was not achieved.
When Sweden decided to publish new
requirements on the basis of ISO standards, Finland made a similar
decision in the middle of the 1960’s. During the 1960’s, the contacts with
Sweden had generally become
more important: for example, VTT Technical Research Centre of Finland
had started a research project
dealing with prefabricated residential houses as knowledge of problems in
their sound insulation was got
from Sweden.
The paper is based on analysis of the
contemporary research reports from the 1940’s to 1960’s, drafts for
requirements and articles published in the Finnish journals. As an archive
source, also the material of the
Acoustical Society of Finland is used.
