Treble simulation of empty rectangular rooms with porous absorbers


Diffraction is a prominent low frequency phenomenon that is known to be difficult to simulate with traditional geometrical acoustics (GA) software even with some compensations. Treble outperforms the conventional GA software in simulating diffraction from a large barrier by directly solving the wave equation as shown in the BRAS (Benchmark for Room Acoustical Simulation) RS5 scene. This study compares Treble simulations and BRAS for the RS6 scene called finite diffracting body.
In this paper you can see how Treble's simulation validated against BRAS rs6 data on sound diffractions around a finite obstacle at low frequencies.
