Advanced Strategies for Sound insulation and noise and vibration control

Recommended Prerequisites

It is recommended that the student has previously attended the unit Advanced concepts of Acoustics and Vibrations.

Teaching Methods

In teaching the course, it is anticipated the presentation of theoretical concepts and advanced knowledge on the topics defined in the syllabus. Relevance is given to the study of specific cases that may be the basis of research proposes.

Learning Outcomes

This unit aims to provide students the possibility of acquiring skills in the area of building acoustics, in particular with regard to sound insulation and noise and vibration control.

Students should acquire knowledge in advanced prediction and modeling tools to apply in the evaluation of building acoustic situations and also on experimental alternative tools to approach problems related with the research and product development.

They must be able to identify and propose constructive solutions for new applications realted with research and product development process.

It is intended that students develop skills of analysis, problem solving, critical thinking and practical application of theoretical knowledge that allow to perform research in the field of noise and vibration control.
