Presentation
The Acoustics curricular unit was pedagogically defined and structured so as to deliver a set of theoretical-conceptual references around the physical properties of sound in its material, spatial and organological contexts. The study of these acoustic phenomena is complemented by an in-depth approach to the various graphical representations of sound, measuring instruments and analysis. In this programmatic context, in addition to the physical considerations, the understanding of sound in the domain of the perceptible (psychoacoustics) is also favoured, emphasizing the particularities and non-linearities of the human auditory system. In this way, the theoretical foundations necessary and indispensable for a good academic performance are built up, providing ground for disciplines of more practical demand.

Objectives
Objectives
The main intended learning outcomes involve the acquisition of theoretical knowledge about sound in specific reference to the physical, psychoacoustic and organological, aimimg for its practical application in the studio context. The physical, behavioural properties of the wave movements in several practical contexts and their correlation with the reality of the psychic-auditory system are studied. Concepts associated with the fields of graphic analysis and electroacoustics (sound technologies) will be addressed to contextualize students around a specific lexicon and specialized technical concepts around analog and digital systems and in this regard induce students the universe of studio equipment. Students should demonstrate knowledge in the understanding of physical and psychoacoustic phenomena of sound, interpretation of graphic representations, and develop a solid technological culture.

Teaching methodologies and assessment
Teaching methodologies and assessment
Verbal exposition of concepts and ideas assisted by slide shows will be joined by the use of the personal computer as an analysis and research tool. Some concepts will be demonstrated in a practical way and a series of task-challenges will be deployed, culminating in class discussions.
