The Acoustic Design for Buildings course deals with topics of interest for building design and building renovation. In particular, the issues of acoustic design of buildings are addressed, in terms of the acoustic requirements of the building components, of the control of the noise of the systems, and of the acoustics of the rooms. A lot of time is left for learning computing tools.
The course will deliver competence in building acoustics for design of buildings and rooms in buildings so that the acoustic environment fulfills the requirements from community and users. Competence should include understanding the effect of noise loads from internal and external sources and the use of theoretical and empirical methods to design buildings with satisfying sound insulation against noise. The student will also develop skills on room acoustics, i.e. develop understanding of how sound spreads in volumes and what it takes to achieve desired sound quality in rooms by using modeling and analysis. Finally, the course will give knowledge of measuring technique for room acoustics and sound insulation.
The course aims to provide to the student the necessary skills to deal with the acoustic design of buildings in all its different aspects and in specialized terms. This is achieved by training students both in terms of theoretical skills and in the use of the most recent numerical calculation tools. A lot of time is left for laboratory activities and field exercises. Students then learn to use numerical calculation tools for the different areas related to the acoustic design of buildings. Particular attention will be paid to the acquisition of techniques for reclamation and renovation works on existing buildings.
Having passed the examination of Applied Acoustics and Lighting.
The course consists of about one third of lectures, one third of lab or field exercises, and one third of computer activities aimed at learning the use of specialized computer programs.

All class schedules are posted on the EasyAcademy portal.
The exam is oral.
During the oral exam, for the topics covered in class (Acoustic design of the rooms, Acoustic building design, Impact assessments and acoustic climate, Noise control of HVAC systems, Noise in the workplace) questions are formulated to test the understanding of the topics. The exam tends to favor, in addition to the theoretical elements, aspects of an applicative and engineering nature. Students may be required to discuss and comment on projects and activities developed during the exercises.
