Abstract
For students just starting out in acoustics, some basic concepts can be terribly difficult to understand. Ideas like plane, spherical, travelling, standing, and evanescent waves are easily described mathematically but can be difficult to understand physically. The use of animation to show the particle motion, velocity, and/or pressure fields associated with these wave motions helps to solidify the understanding of the basic physics. In noise control, students often have problems conceiving the effects of reverberation on acoustic signals and the perceived noise reduction from various acoustic treatments. These acoustic effects can be simulated through the use of auralization. Animations and auralizations developed using MATLAB, CATT Acoustics, and Cooledit for a senior level architectural engineering undergraduate classes in building noise control and acoustical room design will be presented.
