Detailed view
Semi-anechoic room for acoustic analysis
Named "Marin Mersenne" after a philosopher, mathematician, scientist and music theorist who was the first to measure the speed of sound in the air around 1630, this equipement on the UMRAE site in Nantes contributes to the development of scientific knowledge in the field of acoustic propagation in the environment. The semi-anechoic room is an acoustic test room, allowing in particular to carry out acoustic measurements in urban models, to develop acoustic measurement devices, to characterize the acoustic emission of noise sources, to calibrate measurement systems...This room is characterized by a very high level of isolation (very low background noise level) and by a specific interior treatment allowing to simulate the propagation in open field.

The platform in detail
The equipment allows the study of many phenomena of emission and acoustic propagation, related to the issue of noise in the environment, as well as the development of measurement systems. As an example, this equipment has been used in the following studies :
. study of the acoustic propagation in streets, from urban models;
. development and calibration of systems for measuring the acoustic impedance of surfaces;
. study and development of noise reduction devices in building facades;
. study of the acoustic reflection by urban facades and natural soils;
. characterization of the acoustic emission of noise sources;
. development of low-cost acoustic sensors.
The equipement is sometimes used for student practical exercices in the frame of collaborations with Le Mans Université.
