M1 - Basic Acoustics: Understanding the Loudspeaker
, University of Waterloo - Waterloo, Ontario, Canada
This presentation is for AES members at an intermediate level and introduces many concepts in acoustics. The basic propagation of sound waves in air for both plane and spherical waves is developed and applied to the operation of a simple, sealed-box loudspeaker. Topics such as the acoustic impedance, compact source operation, and diffraction are included. Some live demonstrations with a simple loudspeaker; microphone and measuring computer are used to illustrate the basic radiation principle of a typical electrodynamic driver mounted in a sealed box.
