The aim of the course is to provides the basic knowledge of applied acoustics to be used in main practical case of technical interest for mechanical and energy engineers referring particularly to acoustic impact from technical components.
The course is based on theoretical lectures, practical application and laboratory activity.
General concepts. Physic acoustics. Sound Pressure Level. Intensity and Power Level. Sound propagation. Audiogram. Sound Meters. Microphone characteristics. Equivalent levels. Spectral analysis, Indexes and sound criteria. Acoustic dosimeters. Acoustic intensity and acoustic power determination. Sound propagation in free field. Sound propagation in rooms. Acoustic reverberation. Acoustic properties of materials. Diffusive and normal incidence sound absorption and its determination by reverberant rooms and by standing waves tubes methods. Insulation panels assembly. Noise control. International standards for measuring techniques on materials and for noise evaluation in buildings.
