Ceiling testing facility: Optimizing the airborne and impact sound insulation of lightweight ceilings and roofs
In our ceiling testing facility, flat roofs or lightweight ceilings can be installed according to DIN EN ISO 10140 (wooden ceilings). These include flat roofs, industrial roofs, wooden beam ceilings, solid wood ceilings and wood-concrete composite ceilings. The airborne and impact sound insulation of the ceilings, installation noise from bathtubs and shower trays, as well as the reduction of impact sound from screeds, hollow and raised floors, suspended sub-ceilings and much more can be measured effortlessly in the testing facility. The ceilings or roofs are installed on a circumferential bracket. The dimensions of the test object are approx. 4.78 x 3.78 m (L x B).
Contact us to find out more about optimizing the airborne and impact sound insulation of lightweight ceilings and roofs. We would also be happy to help you optimize the acoustic properties of your ceiling and roof constructions. Our experts look forward to hearing from you.
