Sound insulation in a door test laboratory

At the Fraunhofer IBP door test facility, the airborne sound insulation of doors, door leaves, and panels is measured in accordance with DIN EN ISO 10140-1 to 5. Two soundproof reverberation chambers, separated by a highly sound-insulating wall with a standardized test opening, enable the evaluation of acoustic properties. The use of cladding effectively suppresses flanking transmission within the rooms. The test facility also offers flexibility for testing a wide range of components, including partition wall sections and additional cladding. With the help of state-of-the-art measurement technology, reliable and standard-compliant data for acoustic optimization can be generated.

Benefit from our cutting-edge testing technology and the extensive expertise of the Building Acoustics Group. Our tests identify weak points, optimize products, and ensure compliance with the highest regulatory standards. The result: acoustically optimized doors and building components that not only meet legal standards but also leave a lasting impression on your customers – an investment in quality and competitiveness.
