Principal Content: Audio Discrimination
Pedagogical objectives
- The student is able to identify an anomaly within a sound.
- The student is able to isolate a sound-fragment with the selection-tool
- The student is able to identify a sound by its visual representation of the wave-form
Pedagogical intentions
- Improve the auditory discrimination of the students
Tools
Process
- The teacher asks the student to choose the sound [Intruder 1]
- The student listens to the sound in order to locate the anomaly that is hidden and, using the selection-tool, isolate the “accident” in question.
- Once this is accomplished, the student raises their hand and the teacher confirms. If successful, the student is invited to continue the game by finding and isolating each successive anomaly.
Use of the metronome makes it possible to slow down the selected sound-fragment (anomaly), making it easier to analyze.

Proposal for a creative activity
Proposal for a creative activity: Benoît Côté
After this game, I often propose the following creative activity, to be experienced by the entire class or in smaller groups of 5 or 6 students:
- Using the available sound-banks, the class must create a homogenous soundscape (in a forest at night, city sounds, a day in the park etc.) Something simple but something that demands nonetheless, a certain finesse in blending and balancing the volume of all of the sounds.
- Add a heterogeneous sound that doesn’t fit into this ambiance. At this point, we have the beginnings of a story, a sonic narrative that can move forward (i.e. Why is this sound there? Where did it come from? How does is initiate change?)
