Impact noise performance (IIC) assessment web-app development
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, A7hz 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.
Noise Urban Observatory – Environmental science study on urban noise planning
The aim of this study was to collect best urban noise changes monitoring and planning practices around the world and to assess the possibility of their application in Canada and in particular in Montreal. In our Quebec context, it is not today possible to characterize the urban noise evolution over time because no precise and organized archives exist. The project aimed at first to identify the world organizations responsible for observing urban noise changes and then to collect monitoring, management and reduction of urban noise (direct or indirect) methods.

High Acoustic Quality of a Building – BAbel Method
BAbel is a method of evaluating the acoustic performance of a building. It ensures that all the acoustic details of a building are taken into account. Using the BAbel method is to ensure that the different spaces of a project have been designed for comfort and acoustic compliance. The method reviews all the possible aspects of acoustic and vibration transmissions (airborne, groundborne, hybrid, etc.) between the elements of a building in order to orient them towards the most suitable solutions. The interdependencies between the elements of a project and the different mitigation solutions are considered.
