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 and Building Acoustics.
Knowledge: To describe the key concepts of environmental and building acoustics .
Comprehension: To interpret and manipulate the elements and numerical data. To identify the (acoustic) characteristics of the construction elements and assign them indicative parameters of its performance in terms of acoustics efficiency.
Application: to establish procedures and analysis algorithms to identify the most acoustically efficient.
Analysis: to rank the results of the application of the valuation methodologies.
Summary: to understand and to be able to propose new solutions to improve acoustics in building construction.
Evaluation: Evaluate the methodologies used and to forecast the evolution that they may follow.

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 power lines - noise in wind power 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) - Speech intelligibility (voice characteristics, parameters SIL-AI-AC-RASTI, open spaces, privacy)
6- Architectural Acoustics - variable acoustics - diffusion/reflection/scattering - auditorium design - modeling (mathematics and physics) - Electroacoustics
7- Community noise - social aspects - Regulations (RGR- Regulamento Geral do Ruído: Portuguese Noise Code; RRAE: Regulamento dos Requisitos Acústicos dos Edifícios – Code for building acoustics; workers protection; etc.) - Environmental impact studies - Normalization and accreditation.
8 - Acoustic Rehabilitation in Old Buildings.
9- Vibrations [only if available time]
10- Measurement and Analysis Instruments - microphones, sound-level meters, dosimeters, analysers, etc.
11- Conclusion
DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:
At a time when innumerable legislation on Acoustics exist it is crucial that students (...and future engineers) have the ability to read, understand and apply it. The acoustic comfort is also, increasingly, one requirement demanded by users of most diverse spaces.
This course will be based on the oral presentation of the themes (with many audiovisual supports), where examples of real situations will be given. Practical classes will be based on problem solving, practical experimentation of measurements, as well as application of regulation (in the FEUP Lab. of Acosutics). Students who are 10 or more minutes late cannot attend the theoretical classes, and the Attendance Sheet will be given only up to 15 minutes after the Practical classes have begun.
DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
Establish process and algorithms of concept and constructive analysis to identify the most efficient from the desired point of view. Rank the results of the application of assessment methodologies and strategies to choose solutions. Understand and propose new solutions to improve the quality construction. To evaluate the methodologies used and predict directions of evolution that they may follow.

Achieving final classification requires compliance with attendance at the course unit, according to the MIEC assessment rules. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for each of the classes’ types is not exceeded.
100% Exam
An excelent attendance to classes will be taken into account in a positive more favorable rounding in the final grade.

SPECIAL RULES FOR MOBILITY STUDENTS:
Proficiency in Portuguese;
Evaluation by exam and/or coursework(s) defined in accordance with student profile.
In the exams students cannot use mobile phones (or even have them on the table).
If students attend classes (theoretical and practical) regularly (100% attendance), this will be taken into account.
Estimated working time out of classes: 4 hours/week
