Sound insulation in a wall test laboratory

The P2 wall test stand at Fraunhofer IBP is specifically designed to determine the sound insulation of wall constructions in accordance with DIN EN ISO 10140-2. Equipped with two surrounding joints to effectively suppress flanking transmissions, it enables reliable testing of highly sound-insulating building components, such as cinema partition walls or installation walls. The test stand allows wall constructions to be mounted up to the bare ceiling or below a lintel with integrated Halfen channels. Its large test opening and drivable equipment provide maximum flexibility for analyzing solid and lightweight walls, mobile partition walls, and facade elements. A standout feature of the P2 test stand is its ability to precisely evaluate sound insulation at low frequencies – a crucial factor for achieving acoustic excellence.
