The ESI Group team is pleased to announce the availability of FOAM-X 2018.0, is a standalone utility used for defining acoustical properties of open-cell porous materials, perforated plates and resistive layers from impedance tube measurements.

About ESI FOAM-X. Foam-X: standalone utility for quick characterization of the acoustic properties of open cell porous materials from impedance tube measurements. Defining the acoustic properties of porous noise control treatments is a critical part of the acoustical design process in a simulation software. FOAM-X calculates the required acoustic material properties from standard tests.

FOAM-X uses identification algorithms that works with acoustic data output from ASTM E1050 and ISO 10534-2 impedance tube tests or ASTM E2611 transmission tube tests to identify porous material properties. From sound absorption coefficient or dynamic bulk modulus and dynamic bulk density, it calculates the main acoustic properties of open-cell porous materials: open porosity, static airflow resistivity, tortuosity, viscous and thermal characteristic lengths, thermal static permeability, Young’s modulus, Poisson’s ratio and damping loss factor. Features:

- FOAM-X software works with all standards ASTM E1050, ISO 10534-2, and ASTM 2611 impedance and transmission tube equipments (Direct Acoustic Test Method).
- FOAM-X can characterize many different types of open-cell porous materials (foam, fiber, perforated plate, resistive screen, fabrics, etc.).
- FOAM-X can also characterize each of the following frame type (rigid, limp, elastic).
- FOAM-X allows you to extract: Static airflow resistivity, Open porosity, Viscous characteristic length, Thermal characteristic length, Tortuosity, Thermal static permeability, Young’s modulus, Poisson’s ratio, Damping loss factor
- FOAM-X has also a simulation and a sensitivity tool (analytical and numerical solver) taken into account of boundary conditions (clamped, slinding, air leaks).
- Since 2016, FOAM-X has its own database to store the identified materials and compare them.
- FOAM-X writes out characterization results in a compatible XML format with ESI Group VA One and Nova.
