"Classe Techno," is a science fair originating from the "24 heures des sciences" (www.sciences24heures.com) provincial initiative, and organized annually or bi-annually since 2010 by the communication services from École de technologie supérieure (ÉTS), an engineering school part of the Université du Québec network. This event is designed for high school students coming from a variety of socio-economic origins in the greater Montreal area and is designed a full-day workshop with relevant and interactive hands-on experience for students in upper middle grades (K-8 to K-11). As part of this event, the acoustic team of ÉTS offers a dedicated workshop animated by graduate students and researchers within the well-equipped ICAR (icar.etsmtl.ca) acoustical research labs, on the topic of Noise ("Bruit" in French). The "Bruit" workshop exposes the students to a variety of key-concepts and lab experiments about mechanical and sound waves, noise and music. The 60-minutes long workshop is structured around 3 main activities: a) "What is sound?" b) "What is music?" and c) "When is it too loud?" and exposes students to a several experiments, ranging from measurement of frequency and magnitude of mechanical waves, to interference of waves to sound synthesis and Fourier analysis using sound card, to the assembly and calibration of a sound level meter and to the proper use of hearing protection devices. This paper presents the workshop structure and details each of the animation together. It provides some reflexion on what worked since day one in 2010, what has been improved over the years and what could be done in the future.
