ME 566 Acoustics
2009-2010- Spring
Introduction to oscillations, waves, and sound generation and propagation. General concepts such as quantitative measures of sound, plane waves, and acoustic energy density and intensity. Perception of sound. Derivation of wave equation. Reflection, transmission and refraction of sound. Normal modes: vibrating membranes, and sound in a rectangular enclosure; room and duct acoustics. Acoustic horns. Absorption and attenuation of sound waves. Acoustic waves in spherical co-ordinate systems.
