Reproducibility of measurements with ISO 140 and calculations with EN 12354 (NT TR 603)

NT TR 603

  • Uncertainties of measurement and prediction of the sound insulation in a building is an important issue to the building industry, because they put increased expenses on all actors of the building process who have to keep safety margins to prescribed requirements. This report deals with estimates of both types of uncertainty and some recommendations on suitable safety margins are given.

Laboratory measurement of sound insulation in the frequency range 50 Hz to 160 Hz – A Nordic intercomparison (NT TR 489 - edition 1)

NT TR 489 - Edition 1

  • Five Nordic laboratories have carried through an intercomparison concerning laboratory measurements of sound insulation at low frequencies. Measurements have been carried out on two different test objects – a sandwich steel plate and a window - in the frequency range 50 Hz to 160 Hz according to ISO/DIS 15186-3, which describes a new test method based on intensity technique.

Doors in buildings: Airborne sound insulation (NT ACOU 069)

NT ACOU 069

  • This NORDTEST method describes how to determine the sound reduction index of doors in buildings, i.e., in the presence of surrounding party walls whose contribution to the sound transmission may be significant.

Small building elements: sound insulation (NT ACOU 037 withdrawn)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