Learning unit contents

Course description :
This course is an introduction to building acoustics and interior lighting techniques. The basic principles of applied acoustics are presented and explained. It is then shown how to evaluate discomfort and annoyance through specific indicators. This first part ends with some notions in room acoustics. The introduction to lighting techniques begins with the basic principles of photometry, then the properties of the different lamps and luminaires are described. Finally, the problems in interior lighting design are briefly discussed.

Learning outcomes of the learning unit

At the end of the course, it is intended that the student will be able to: - understand the basics of sound propagation and its different modes, - evaluate and measure sound levels in decibels and combine the contribution of several sound sources, - understand the basics of psychoacoustics and the origin of the dBA, - understand and apply some noise indicators describing discomfort, in particular equivalent noise levels, - calculate and measure reverberation times (absorption necessary to reach a given RT),
- understand and apply the basic photometric quantities used in lighting techniques, - understand recommendations, technical documentations or standards published in the lighting techniques literature, - apply the basic laws of photometry (for example to calculate the illuminance in simple situations), - identify the different types of lamps, their properties and applications, - propose a quick evaluation of an artificial lighting installation for an interior space.

Prerequisite knowledge and skills

Basic mathematics and physics for engineers.

Planned learning activities and teaching methods

First of all, this course is organised in modules, each of them consisting in a general presentation ex cathedra, followed by applications and exercices with the teacher.
Lab' demonstrations will be organised, when possible.

Mode of delivery (face to face, distance learning, hybrid learning)

Face-to-face learning.

IMPORTANT: the COVID-19 health situation could possibly modify this organization.

Organisational adjustments related to the current health context

Recommended or required readings

The documents and slides will be made available to the students who are registered to this course via myULg.

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

Any session :

- In-person

oral exam

- Remote

oral exam

- If evaluation in "hybrid"

preferred in-person


Additional information:

Face-to-face
The evaluation is first based on an oral examination during which the student will answer to questions concerning the theory that has been exposed during the presentations ex-cathedra. He/she will also solve some exercises (bringing a calculator is essential).
 
On-line
Interview during approx; 45 minutes, including some exercises (bringing a calculator is essential).
