Acoustics and Ultrasound sector carries out research, development and service activities in the field of acoustic and ultrasonic measurements, with particular emphasis on reference metrology and the transfer of expertise to the industrial, healthcare and environmental sectors. Its activities include the realization and maintenance of primary standards, the characterization of transducers, as well as the development of advanced measurement methodologies for quantities such as sound pressure, acoustic power and ultrasonic parameters. 

A relevant area concerns acoustics applied to environmental monitoring, health and safety, including studies on exposure to noise and ultrasound, assessment of acoustic impact, and technical-scientific support to national and international standardization. 

In the field of ultrasound, the sector operates in biomedical applications, contributing to the definition of reliable and traceable measurement procedures. 

The sector is actively involved in national and European research projects and participates in technical committees and standardization working groups, fostering the integration of metrology, technological innovation and standardization.
