Small building elements: sound insulation (NT ACOU 037 withdrawn)

NT ACOU 037

  • This document specifies a laboratory NORDTEST method of measuring airborne sound insulation of such small building elements as are defined under clause 2. The document also establishes directions about reporting and applying such test data.

    The results obtained may be used to develop building elements with approbiate acoustical proprties, to classify such elements according to their sound insulation properties and to etimate their influence on the sound insulation of partition constructions in buildings.
