Technical Installations / ICPE

Technical installations represent a major source of noise in both the built environment and surrounding areas. LASA has developed expertise based on hundreds of case studies involving isolated technical installations, as well as installations classified under ICPE (facilities classified for environmental protection purposes). For industrial and environmental measurements, our extensive portfolio of acoustic and vibration measurement equipment enables us to address a wide range of technical challenges.

Dynamic airflow network noise calculation tools, combined with 3D acoustic propagation modelling software for outdoor environments, allow us to account for the acoustic effects of buildings, screens, topography, and long-distance meteorological conditions. This enables the prediction of indoor and outdoor sound levels across a wide variety of scenarios.

Acoustic measurement missions ensure compliance with regulatory noise emergence limits in the environment (residential areas, sensitive zones) through both short-term and long-term monitoring campaigns. Vibration measurements are carried out as part of environmental impact studies for industrial sites and construction projects, in order to identify vibration sources or define solutions to limit their propagation within buildings or the surrounding environment.

Study missions are also carried out to produce the acoustic and vibration components of environmental impact assessments for classified facilities, or to predict noise and vibration levels generated by any technical installation in its environment.

Design and sizing missions for mitigation solutions are proposed in order to define the technical characteristics of the required compensatory measures (acoustic screens, enclosures, anti-vibration mounts, sound traps, etc.).
