Full bandwidth wave-based simulations using Treble


The study measured the capabilities of Treble’s wave-based solver in a medium-sized room of 80 cubic meters. The solver was tested for full-bandwidth up to 8kHz and both mono and binaural room impulse responses (RIR) were measured using a directive source and a KEMAR mannequin at various positions. The simulations were carried out on a cluster with six Nvidia A100 GPU cards running in parallel. Results are compared and presented for Energy Decay Curves and derived acoustical parameters, reverberation time T20 and early decay time, for the mono RIR. The binaural RIR results are compared both in the frequency domain and in the time domain.

What you'll find

  • Full bandwidth wave-based virtual acoustics with directive sources and receivers.
  • Simulated binaural rendering using 16th order ambisonics using an virtual spherical microphone array.
  • Simulated results showing an excellent match with measurements up to 8kHz.

Treble simulation of empty rectangular rooms with porous absorbers

The sound field in a rectangular empty room becomes more or less two-dimensional with a porous ceiling absorber since the vertical sound field energy diminishes more quickly than for the horizontal sound field. In such a condition, the porous ceiling absorber can lower the reverberation time effectively at low frequencies. This documentation shows how the sound field changes with two different porous layer configurations in both measurements and treble simulations.
