Assessment(s)
N°	Nature	Coefficient	Observable objectives
1	To assess the ability to use the theoretical knowledge learned in class in a simple concrete context (1 to 5)	1	The written exam consists of a series of questions on the course followed by several exercises proposing a simple acoustic configuration to study.
