Cylindrical Subwoofer
Model 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.

Acoustic pressure inside and around the subwoofer. The pressure rapidly approaches zero as the distance to the loudspeaker increases. |
