New techniques and industrial processes emit infrasound or ultrasound (wind turbines, heat pumps, ultrasonic cleaning systems...), while the mechanism of sound perception outside the hearing range is currently not well understood. Manufacturers and operators of these installations need noise emission regulations to be well-founded and not unnecessarily restrictive: it is therefore necessary to define rational and substantiated criteria to prevent the risks associated with these sounds.


Understanding human perception of non-audible sounds

Define the metrological structure necessary to apply safety criteria based on sound perception thresholds

Provide traceability to national standards through the development of a universal ear simulator to model human ear impedance for both adults and children
