Acoustic PDEs and Boundary Conditions

Topic
Overview  »

Acoustics is the field of physics that models sound by changes in pressure. Two approaches to model acoustic systems are common: one approach is to model acoustics in the time domain and the other is to model in the frequency domain.

Functions

AcousticPDEComponent — model acoustics in the time or frequency domain

AcousticAbsorbingValue — truncate an infinite region to a finite one

AcousticImpedanceValue — model partially sound-transparent boundary

AcousticNormalVelocityValue — model sound sources on the boundary

AcousticPressureCondition — set a pressure source at the boundary

AcousticRadiationValue — model sound sources and sinks on the boundary

AcousticSoundHardValue — model an acoustic wall on the boundary

AcousticSoundSoftCondition — set pressure equal to the ambient reference pressure
