Acoustics and Vibration Laboratory
The Acoustics and Vibration Laboratory (UAVE) is integrated in the Acoustics, Lighting, Building Components and Facilities Unit that is part of the Buildings Department of LNEC.
This laboratory was established in 2005 in response to the need to support studies aimed at acoustic characterization of solutions and systems used in building construction.
Additional information can be found in this laboratory's flyer.
Activity areas
UAVE’s activity is mainly focused on the characterization of the acoustic performance (absorption and sound insulation) of construction building materials and systems, particularly:
- partitions walls, façade elements, glazing, doors, small technical elements, acoustic linings, shutters, floor and floor coverings;
- noise barriers;
- building materials and sound absorbing systems.
Testing
UAVE performs the following laboratory tests for characterization of the acoustic properties of elements and/or building systems:
- airborne sound insulation;
- impact sound insulation;
- sound absorption of materials and systems in diffusive fields;
- sound absorption of materials at normal incidence (impedance tube);
- sound power levels of noise sources from the measurement of sound pressure.
Other services
In addition to the characterization studies, usually associated with research under contract services, UAVE also develops activities in different areas, such as:
- research studies in the field of buildings acoustics and vibration in buildings, environmental acoustics, and human perception of noise and vibration in buildings;
- expert advisory and support to the acoustic design for new construction, conservation, and rehabilitation of buildings;
- acoustic characterization of new materials and systems;
- expert advisory as refers to environmental impact studies within the framework of the acoustic component of the environment and environmental vibrations.
