A New Concept for the Acoustic Requirements in the Norwegian Building Regulations

Abstract

A new concept for building regulations together with sound and vibration classification standards are introduced. The regulations, which are harmonised with EC directives, specify general acoustic and vibration requirements. A new Norwegian Standard, NS 8175, was prepared in parallel with the new technical regulations. The standard specifies the detailed technical acoustic requirements and classes for the various types of buildings concerned. The sound insulation and noise criteria are given in four classes A, B, C and D. The classification system makes it possible to choose better acoustic qualities and climate in buildings. Another new standard, NS 8176, containing a measurement method for determining vibrations from heavy road and rail transport, and a similar classification system as for acoustic conditions, based on dose-effect relationship, is in preparation.
