喇叭的声学分析：基于 Westervelt 模型分析非线性声波传输
Application ID: 54021
This tutorial shows how to include local nonlinear effects when simulating the acoustics of an exponential horn. Nonlinear effects become important when an acoustic horn is used for high amplitude signaling.
The Nonlinear Acoustics (Westervelt) feature available for the Pressure Acoustic, Transient interface provides nonlinear contribution to the linear acoustic wave equation. The model also includes the Exterior Field Calculation feature which, accompanied by the Time to Frequency FFT study step, makes it possible to visualize the Radiation Pattern of the acoustic field at any given distance from the source.
