We develop software products and experimental test rigs to model or characterize sound absorbing materials or sound sources.

Experimental test rigs

Matelys provides turnkey equipments developed by Mecanum for full elastic and acoustic characterizations of porous materials used for acoustic applications.
These equipments include:

Matelys also develops on-demand experimental test rigs.
