Abstract
A method is provided for predicting the performance of a loudspeaker port and optimizing port design. The method involves defining the geometries of a loudspeaker port, modeling the bi-directional fluid flow in the defined port utilizing a modeling method known as Computation Fluid Dynamics (“CFD”) and analyzing the flow model to determine whether the flow characteristic displayed in the model represent optimum flow characteristics for port performance. To optimize port design, the geometries of the port may be altered and modeled until the flow characteristic represents flow indicative of optimum port performance.
