7. Acoustic Measurements

8. Acoustic insulation (basic principles)

9. Absorbing Panels

10. Diffuser Panels
11. Ambiental Acoustics - Law & noise.

Methodologies should be applied with the necessary background knowledge to students flexibility in order to bridge any gaps earlier and allow some continuity in the acquisition of knowledge.

Teaching methodologies and provide didactic followed the confrontation of students with information and knowledge, and critical reflection and plurality of opinions, contributing to achieving the goals of UC to reinforce learning of content and skills of the practical exercise of their respective powers.
