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.

Re-watch our recent training webinar in which Jesper Pedersen goes through all the steps involved in the modeling workflow and creating acoustic simulations for in-depth analysis.

The study measured a medium-sized room of 80 cubic meters to test the capabilities of Treble's wave-based solver and solving for full-bandwidth up to 8kHz. Both mono and binaural room impulse responses (RIR) were measured using a directive source and a KEMAR mannequin at various positions. The source is modeled by including the geometry of the speaker box directly into the 3D room model and then applying an impulsive surface velocity excitation to the loudspeaker membrane. 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.

We are thrilled to announce that our newest update for Treble Acoustic Simulation Suite is now live, and it comes with a bunch of exciting features that will make your acoustic simulations more realistic, interactive, and fun!

The round robin 3 study examined a small but complex room with special diffusors. The room was measured and the material properties of all surfaces in the room were obtained in octave bands 125 Hz - 4k Hz. The study used over 20 simulation tools to simulate the studio room of PTB institute. Results were given both with open curtains and closed curtains. The Schroeder frequency of this room is calculated Hz. A strong standing wave was present in the room and a large part of the wall area could be covered with curtains.

Incorporating sound into design schematics has long been a major pain point for acoustic engineers and consultants. Attempting to calculate the wave equation can be an extremely laborious and time-consuming task restricting the speed and workflow of projects. Currently, the predominant geometrical acoustics ( GA) approach to sound simulation is, although useful, only approximate failing to offer the required accuracy at low and medium frequencies. However, recent developments in wave-based acoustics are ushering in a new age of sound simulation, in which engineers can reliably and accurately model complex wave phenomena within virtual environments.
