Geometrical simulations in Acoustics
This blog delves into how Treble’s geometrical solvers operate, their technical strengths, and why they’re indispensable for acousticians and design professionals seeking efficient, scalable sound solutions.
Abstract
When a rectangular room is empty and has a porous ceiling absorber, the sound field becomes quasi-two-dimensional. This is because the vertical sound field decays faster than the horizontal sound field due to the absorption. As a result, the porous ceiling absorber cannot reduce the reverberation time effectively at low frequencies. This paper demonstrates how the sound field varies with two different porous layer configurations using both measurements and Treble simulations.
This shows that Treble can account for interference by including the phase information. This is delightful news for room acoustic simulation software users, as not many energy-based GA can do such accurate simulations.
