	Objectives
	TO UNDERSTAND THE FUNDAMENTAL CONCEPTS OF 1, 2, N DOF MECHANICAL VIBRATIONS. TO MODEL MECHANICAL SYSTEMS AND DETERMINE NATURAL FREQUENCIES, DAMPING RATIOS, AND RESPONSE TO PERIODIC FORCING FUNCTIONS. TO UNDERSTAND THE FUNDAMENTALS OF SOUND PROPAGATION AND OF ACOUSTICAL DESIGN. TO DEVISE PROPER INSTRUMENTATION SYSTEMS TO CHARACTERIZE NOISE AND VIBRATIONS ACCORDING WITH THE ITALIAN LAWS.

	Prerequisites
	Basic knowledge of Mathematics and Physics.
