FISICA TECNICA INDUSTRIALE E AMBIENTALEModule FISICA TECNICA AMBIENTALE
Academic Year 2023/2024 - Teacher: GIANPIERO EVOLAExpected Learning Outcomes
The course provides students with the ability to evaluate the parameters that determine the quality of work environments, and any health risks, in the field of acoustics and vision. Students will learn to measure these parameters, compare them with any optimal or regulatory values, and then establish and implement - together with a technician - the most appropriate mitigation strategies.
