Elwis
The latest member of the measurement systems family is called ELWIS. ELWIS gives the possibility to quickly make a full characterisation of porous materials. The structure and acoustic material parameters are needed for simulation of materials and sound packages. The process - and the measurement tool - are easy to operate, and, thanks to its unique software, it can also guide users with limited specific expertise in porous materials acoustics to correct results.

New software for ELWIS
ELWIS is now available with new software. The data evaluation is now even faster and easier thanks to an automated analysis procedure that supports the user. The possibility to generate a report allows the user to get an overview of all the material parameters as well as averages and standard deviations.
