| Résumé | In recent years, the focus for controlling sound transmission in buildings has shifted from the performance of individual building elements such as walls or floors, to the performance of the complete building assembly. Emphasis is now placed on flanking sound transmission which in some building designs can be the dominant transmission path between adjacent rooms.
A standardized procedure for predicting sound transmission between adjacent rooms in a building inclusive of the first order flanking paths between them has been published by the International Organization for Standardization (ISO) in the form of the standard, ISO 12354-1. The calculation procedure outlined in ISO 12354-1 and the companion standard, ISO 10848 uses laboratory test data for sub-assemblies such as walls and floors and the structure-borne noise transmitted through the junctions between the elements as inputs to calculate the expected sound transmission between adjacent rooms in a building inclusive of the first order flanking paths. This calculation procedure works very well for some types of constructions, but to successfully use it in a North American context, the incompatibility of the ISO metrics with the ASTM standards used in North America and the low accuracy of the prediction method for the lightweight framed constructions typical of North American buildings needed to be addressed.
This Guide was developed to explain how to work around the limitations of ISO 12354-1 by merging ASTM and ISO metrics in the ISO calculation procedure and by providing guidance for applying extended measurement and calculation procedures for common types of constructions. Examples for applying the calculation procedure to various types of constructions are included to demonstrate how to calculate the apparent sound transmission class (ASTC) rating in different circumstances including when linings are applied. Additional worked examples and measurement data can be found in the NRC Research Reports RR-333 through RR-337. The calculation procedure is also applied in the web application, soundPATHS which is accessible free of charge on the website of the National Research Council Canada.
While this Guide and soundPATHS were developed to support the transition to the ASTC rating for the acoustic requirements for dwellings in the National Building Code of Canada (NBC), the potential application of the calculation procedure goes beyond meeting the minimum requirements of the NBC. The Guide also facilitates design to provide enhanced sound insulation and should be generally applicable to construction in both Canada and the USA. |
