BS EN ISO 12354-1:2017 specifies calculation models designed to estimate the airborne sound insulation between adjacent rooms in buildings, primarily using measured data which characterize direct or indirect flanking transmission by the participating building elements, and theoretically-derived methods of sound propagation in structural elements.A detailed model is described for calculation in frequency bands, in the frequency range 1/3 octave 100 Hz to 3 150 Hz in accordance with ISO 717-1, possibly extended down to 1/3 octave 50 Hz if element data and junction data are available (see Annex I); the single number rating can be determined from the calculation results. A simplified model with a restricted field of application is deduced from this, calculating directly the single number rating, using the single number ratings of the elements; a method to determine uncertainty is proposed for the simplified model (see Annex K).This document describes the principles of the calculation scheme, lists the relevant quantities and defines its applications and restrictions.Cross References:ISO 717-1:2013 ED3ISO 10848-1:2006 (R10) Ed 1ISO 10848-4:2010 Ed 1ISO 15186-3:2002 (R08) Ed 1ISO 10848-2:2006 Ed 1ISO 10848-3:2006 (R10) Ed 1ISO 10140 (all parts)ONORM B 8115EN 29053EN 29052-1ISO 10052:2004 Ed 1DIN 4109:1989 (E)ISO 12354-2:2017ISO 12354-3:2017ISO/IEC GUIDE 98-3:2008 Ed 1ISO 16283-1:2014ISO 12999-1:2014EN 12354-5:2009All current amendments available at time of purchase are included with the purchase of this document.
