ME51300 - Engineering AcousticsFall 2017
Days/Time: MWF / TBA
Credit Hours: 3
To introduce the fundamental concepts of acoustical analysis to engineers and specifically to study wave propagation, sound radiation, absorption and transmission in a manner directly relevant to modern noise control practice. The wave approach to the solution of acoustical problems is emphasized and is compared with modal solution procedures.
The basic concepts of wave propagation in the context of mechanical vibration of simple systems. The fundamental assumptions of linear acoustics through the derivation of the wave equation and its simple solutions in plane and spherical forms. Plane wave transmission through barriers. Issues related to modeling and describing acoustical sources. The fundamental mechanisms of sound generation are emphasized, as is the directionality associated with various source types. Sound propagation in ducts, and the concepts of muffler design. Sound propagation in rooms, especially with respect to the effect of sound absorbing treatments on steady-state and transient sound in rooms.
Simple mechanical systems; Transmission phenomena; one-dimensional acoustical systems; Acoustic wave equation and simple solutions; Sound radiation from simple sources; Room acoustics.
Undergraduate linear systems and/or controls course. The student should be comfortable with the basics of frequency analysis, complex analysis, and vectors.
