Abstract
A draft standard INSTA 122:1997 on sound classification of
dwellings is for voting as a common national standard in the
Nordic countries (Denmark, Norway, Sweden, Finland, Iceland) and
in Estonia. The draft standard specifies a sound classification
system with four classes A, B, C and D, where class C is proposed
as the future minimum requirements for new dwellings. The
classification system is based on limit values for airborne sound
insulation, impact sound pressure level, reverberation time and
indoor and outdoor noise levels.
