Innovation et gestion de programmes synchronisée et collaborative pour les nouveaux programmes
In urban areas, traffic noise can be a prominent source of discomfort, affecting the daily lives of millions of people and potentially diminishing their health and well-being. To create a more harmonious living environment and reduce the risks of noise exposure, legislators are working on establishing acceptable emission levels and imposing limits on pass-by noise (PBN) levels. ISO certification standards are used to make sure vehicle comply with established legislation. This type of certification is required for all types of road vehicles, including trucks, buses, motorcycles, passenger cars and recreational vehicles. For hybrid and electric vehicles, new standards are in place for measuring minimum noise emission. For these vehicles an acoustic vehicle alert system (AVAS) adds exterior noise to ensure pedestrian safety. We offer a complete portfolio of modular hardware for reliable data acquisition combined with comprehensive pass-by noise engineering software. The combination of both results in enhanced accuracy and efficiency, but also delivers engineering insight well beyond the certification procedures as such, for instance by pinpointing root causes of dominant noise contributors.
