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.
