Sound Sources

Standardized acoustic sound sources enable you to assess airborne and impact sound insulation, as well as the insulation performance of building façades. Dodecahedral loudspeakers, impact sound machines, and façade sound sources create defined test conditions for building acoustic measurements in accordance with applicable standards. This supports reliable evaluation, traceable results, and efficient compliance documentation during construction planning and inspection.
