Acoustic PDEs and Boundary Conditions

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
