Technical Acoustic

Summer School · 43096 · Bachelor in Industrial and Mechanical Engineering · 3CP · IT

The course provides an overview of the three main areas of applied acoustics. Starting from notions related to wave propagation, the human auditory system, and sound perception, the course will address the topics of acoustics of confined spaces (absorption and diffusion, reverberation, intelligibility) sound insulation (airborne and structure-borne sound insulation, flanking transmission), and outdoor propagation (with a specific focus on vehicle acoustics).

Lecturers: Federica Morandi

Educational objectives
Knowledge and understanding: 1. Knowledge of the calculation methods described in current technical standards for assessing the acoustic performance of buildings 2. Knowledge of current legislation on acoustic protection in buildings Ability to apply knowledge and understanding: 3. Ability to implement the procedures described in technical standards 4. Ability to develop design and diagnostic skills related to the acoustic protection of buildings 5. Ability to improve these skills in a real case study Independent judgement: 6. Students will be able to evaluate the acoustic performance of existing and new buildings, identify critical issues and suggest solutions Communication skills: 7. Students will be able to discuss the knowledge they have acquired using the vocabulary and technical terms related to the topic covered. Learning skills 8. Ability to engage in lifelong learning through the acquisition of critical tools and critical evaluation of project specifications.
