New EASE Tools Go Beta

2010-05-25 12:13

AFMG SoundFlowAFMG is proud to announce the Beta cycle for a set of new modeling programs related to room acoustics and building acoustics as well as to EASE and EASE AURA.

AFMG SoundFlow is a newly designed software for simulating sound propagation in multi-layered walls. Based on the physical properties of the building materials and the configuration of the wall structure it calculates the absorption coefficient and reflection coefficient as well as the transmission loss for all frequencies and angles of incidence. Its algorithms make use of the fundamental theory of sound absorbers as developed by Mechel, Bies and others. Calculation times are short and results can be exported immediately. Computed absorption data can also be imported directly into EASE.

Another tool expanding the capabilities of the EASE software and its modules is the new AURA-Remote program. As a plug-in to EASE it allows all AURA users to speed up their calculation times by orders of magnitude using the remote server farm of AFMG. EASE users can launch the calculation service directly from within the EASE user interface. However, AURA calculations are not performed on the local PC but on a massively parallelized computer cloud. After the calculation is finished, results can be downloaded and viewed in EASE like normal. In addition to gaining the speed increase users may also submit multiple calculation jobs at once and let the calculation network carry them out independently without requiring further user interaction.

AFMG Reflex

Last but not least, AFMG finally publishes a software AFMG Reflex to calculate the scattering of sound waves incident on a structured surface or diffusive geometry. The tool was already demonstrated at recent ASA and ICA conventions and its simulation accuracy compared to published measurement data of various diffusors. The software is using a sophisticated BEM model in the background along with a highly multi-threaded calculation engine to provide results interactively. Polar plots as well as the scattering and the diffusion coefficient can be viewed and exported. Derived scattering coefficients can be used directly in EASE.
