The educational objectives consist in acquiring the physical and psycho-physical basic concepts underlying sound and light perception mechanisms, in the knowledge of acoustical and photometric quantities used in the two areas, of the measuring instruments, of the sound propagation in enclosures and open spaces, of the main types of artificial light sources and of daylighting, of sound-absorbing materials and sound insulation. This represents the basis for the design of the acoustical and luminous environment, both by using simplified calculation methods, and by resorting to the use of dedicated software.
