Objectives

This course aims to endow students with:
- personal and professional skills, so that they can solve problems and make experiments efficiently;
- essential skills, so that they can design in this area;
- essential knowledge on Acoustics, so that they can understand and correctly apply the Portuguese regulations on the area of Environmental Acoustics and Building Acoustics.

Program

0- Introduction to the course
1- Historical background
2- Basic concepts and terminology
- pressure
- intensity
- sound power
- sound pressure level dB
- frequency
- bands
- sound level dB (A)
- time
- Leq, SEL, Ln
3- Hearing system
- physiology
- effect of noise
- protectors
4- Outdoor acoustics
- theoretical concepts
- noise barrier
- traffic noise (road, railroad, air, naval)
- noise in construction sites
- noise in line under very high tension
- noise in wind parks
5- Building Acoustics
- Acoustic correction (sound absorption, reverberation time, direct field and reverberated field)
- Sound isolation and noise control of airborne noise (sound transmission coefficient, sound reduction, sound isolation index, mass law, marginal transmission, single wall, double wall, windows), of percussion noise (sound isolation index, marginal transmission, floating tiles)
- Installation and equipment noise (water and sanitary installation, HVAC, electric equipments, lifts, garages)
- Noise curves (NC, NR, NCB, RC)
- Word intelligibility (voice characteristics, parameters SIL-AI-AC-RASTI, open spaces, privacy)
6- Architectonic Acoustics
- variable acoustics
- diffusion/ reflection
- auditorium design
- modelling (mathematics and physics)
- Electroacoustics
7- Community noise
- social aspects
- Regulations (RGR- Regulamento Geral do Ruído- Regulation for noise; RRAE- Regulamento dos Requisitos Acústicos dos Edifícios – Regulation for building acoustics; workers protection; etc)
- Environmental impact studies
- Normalization and accreditation
8 - Acoustic Rehabilitation in Old Buildings
9- Vibrations [if available time]
10- Measurement and Analysis Instruments
- microphones, sound-level meters, dosimeters, analysers, etc
11- Conclusion

Teaching methods and learning activities

This course will be based on the presentation of the themes orally (with audiovisual support), where examples of real situations will be given. Practical classes will be based on problem solving, practical experimentation of measurement, as well as application of regulation (in Acoustics Lab of FEUP).
Students who are 10 minutes late cannot attend theoretical classes, and the attendance sheet will be given 15 minutes after the practical classes have begun.

Eligibility for exams

Only students who have regularly attended classes can attend the exams. There will be two written exams at the end of the semester with the same level of difficulty (final exam and recurso). They will last 3 hours (theoretical part- 1 hour, closed book exam- 2 hours, open book exam).
Students will only complete the course if they have not skipped more than 3 practical classes.
Recurso exam is only for students who have failed or missed the first exam. Furthermore, students must follow the rule above mentioned.
According to paragraph 3 of Article 4 of General Evaluation Rules of FEUP, students with a special status (working students, military personnel and students who have completed the course in the previous year) can attend the exam.
