This learning situation allows the student to understand the scientific and technological principles used in earphones similar to those used with an mp3 player. The situation places the student in a work environment where he will have to detect functional problems in defective earphones. At the end of this LES, the student will not only be able to explain the principles used, but also to produce a principles diagram. During the course of the process, the student is also faced with certain aspects of his personality. He will thus be better able to mark out his personal and professional fields of interest
