This paper makes a critical return of 15 years of teaching acoustics to student apprentice architects. Learning about acoustics through experience and experimentation is the philosophy developed at the National School of Architecture of Lyon. The experiment starts with listening to the world. Learn to be attentive to all the sounds of our daily environments. This includes workshops, audio-sensitive walks, sound walking, acoustic measurement workshop, sound recording workshop, sound effects, editing and rendering in the form of a sound postcard. This first step involves separating things between the perception and the analysis of measurable acoustic data (leq, max level, frequency analysis, insulation measurement, RT). This type of knowledge is supported by repeatable experiments and measurement protocols in time and space. About the question of ?how to put the architect in a position to anticipate sound atmospheres ?? , our problem responds to pedagogical challenges of identifying skills activated during the different phases of the urban project. The cognitive process of design involves putting in order a series of audible references of sound qualities that memory keeps in sleep in an internal listening of the soundscape (Perianez,1999). These audio references intersect with archetypal typologies, with the identification of sound effects (Augoyard, Torgue, 1995) or remarkable acoustics (Regnault, 2001). The exercises offered to students are akin to experiments to transform the acoustics of an existing place (manufacture of sound models, modeling can complement the graphical tools of geometric acoustics. The teaching method will be primarily experiential learning. Emphasis will be on supporting students to develop a balance between technique, intuition and creativity. Finally, learning can involve the concrete realization of constructive prototypes whose specificities we can measure (luthery objects, music kiosk , acoustic conch) that allow the student to confront the fact and the iteration between this knowledge and the audible results.
