The operation of factories and industrial halls raises two essential acoustic points of vigilance: nuisance to neighbors and the health of people working on site. With regard to the nuisance to the neighbours, according to the legislation, the noise activities linked to the operation must not emerge from the pre-existing noise landscape. Thanks to the Urbanistic Noise Map® (project developed with ADEME), we establish the criteria for maximum permissible sound levels day and night, according to a database of tens of thousands of similar sites to optimize acoustic solutions and not to depend on non-replicable measures in the event of an appeal. As for the question of the hearing health of people working on site, we have developed a digital model center which allows us to model, from the design stage, the sound impact of machines in operation on the environment and people. Thus, we are able to anticipate, integrate and optimize acoustic solutions for buildings, less costly for the contracting authority and respectful of people's health in accordance with the regulations on noise at work.
