Advanced Acoustic Analysis and Design of Enclosures

Recommended Prerequisites

It is recommended that the student has previously attended the unit Acoustics and vibrations in buildings and their envelopes.

Teaching Methods

In teaching the course, it is expected the presentation of basic theoretical concepts and advanced knowledge on the topics defined in the syllabus. Relevance is given to the study of practical cases and solving exercises.

Learning Outcomes

The unit aims to provide students obtaining knowledge and skills in the field of acoustics of enclosed, or partially enclosed areas, covering not only the acoustic conditioning inside the space, but also isolation from the outside and other neighboring areas and acoustic and vibration conditioning systems and equipment. The ultimate goal will be to ensure proper conformation of the acoustic space, depending on their use, and minimize the levels of background noise in the room. It is intended that students develop skills of analysis and synthesis, problem solving, critical thinking and practical application of theoretical knowledge. On the other hand, it also intends that graduates are likely to actively participate in the design and project rooms and enclosures with high acoustic requirements.
