AFMG SoundFlow Acoustics Simulation

Berlin's Ahnert Feistel Media Group (AFMG) is expanding the EASE Suite with AFMG SoundFlow. It allows you to build models of multi-layered wall constructions to predict absorption, reflection and transmission. Models are built from the materials data bank and custom materials can be defined and added to the list. Adjustable scaling and smoothing can be applied, and multiple multi-layered wall compositions can be compared. The software provides the option to investigate the material's behavior for diffuse sound as well as for any specific angle of incident sound, both with an open back or rigid back termination.

Data is displayed using industry standard values including ALPHAw, NRC, C/Ctr, Rw and STC. Professional users can choose between calculation schemes including Bies, ISO / DIN EN 12354, Mechel, Komatsu, Miki or Delany-Bazley. Reports can be produced in PDF and RTF formats for subsequent export to other applications. All graphics can be saved in BMP and PNG formats. For users of EASE acoustic simulation software, SoundFlow Standard also supports the option to directly export data of the absorption coefficients to EASE wall material files. SoundFlow supports both Metric and US measurement systems.

In addition to SoundFlow Basic and Standard versions, AFMG also offers Soundflow Pro, designed for highly specialized applications including research facilities, acoustical engineers and manufacturers of construction materials. It enables analysis of complex characteristics of acoustic models, including acoustical impedance, reflection and transmission factors, as well as frequency-dependent amplitude and phase, in both real and imaginary parts. Soundflow Pro also offers the option of exporting data for use in tabular calculations and other applications. SoundFlow Basic is an affordable alternative for the design of home and project studios and home theater applications. SoundFlow Basic limits its calculations to four layers of construction material, with all calculations performed only according to Bies.

AFMG SoundFlow is available directly from AFMG online.
