Cylindrical Subwoofer

Application ID: 1373

In this model, the acoustic field inside and outside a down-firing subwoofer is computed.

This model is set up in 2D axisymmetry using the Pressure Acoustics application mode. The modeled physical domain is a hemisphere with a radius of 1 m. To minimize the effect of non-physical reflections at the exterior boundary of this domain, an absorbing Perfectly Matched Layer (PML) is added.

The computed results include the near and far-field sound pressure levels as functions of the polar angle.

This model example illustrates applications of this type that would nominally be built using the following products:
