Abstract

To carry out a successful acoustic design of a building, noise impacts between rooms need to be controlled. The acoustic performance is now considered as mandatory for new buildings. ASTM E989-21 defined different ratings to assess the impact noise performance between two rooms such as IIC/AIIC. Considering the lack of existing tools to assess these criteria, and some difficulties to use the existing ones, Atelier 7hz induced an innovation project to develop a new Canadian software. The aim of the project is to create a web app to help acoustic and vibration professionals predict impact sound insulation performance between two rooms. The hybrid method used in the software is based on the addition of measurement databases and calculation models. Floor-ceiling assemblies had been divided into three sections, the floor (rigid-elastic complex), the structural core, and the ceiling. Thanks to a similarity algorithm developed for the project, it is possible to select floor/ceiling assemblies similar to the situation met in the study and to get an assessment of its predictable performance. The algorithm uses exclusive and sorting criteria. It is then possible to modify it by removing, replacing or adding new flooring (rigid-elastic complex) or ceiling. In order to get new situation performances. The Cremer/Ver method has been followed to assess the rigid-elastic complex performance in the app. With this new software, it is possible to navigate quickly onto a large measurement database and partially modify the result. Because the database is an important part of the process, any detailed in situ measurements are welcome from other acoustic and vibration experts.
