Fraunhofer Institute for Building Physics IBPSound Insulation for Room-Height Components and Special Applications in Vehicle, Aircraft and Ship Construction
The PK combined test stand at Fraunhofer IBP is specifically designed to determine the sound insulation performance of room-height components such as doors, windows, window facades, and large-scale partition walls. The test stand meets the requirements of the standard DIN EN ISO 10140-5:2021. Spatial and temporal averaging of sound pressure levels is achieved by means of a pneumatically moved dodecahedron loudspeaker and rotating microphones, enabling highly precise measurements under realistic conditions. To suppress flanking transmissions, a circumferential joint separates the source and receiving rooms. The combined test bench is not only suitable for conventional building components, but also for specialized applications in automotive, aerospace, and marine industries.
By collaborating with us in the PK combined test bench, you benefit from state-of-the-art measurement technology and the expertise of our researchers from the Building Acoustics research group. We provide precise measurements and in-depth analyses of the sound insulation properties of your products, enabling you to optimize the noise reduction and acoustic performance of your components. Our tests help you to meet standards, improve product quality, and strengthen your market competitiveness.
