Laboratory Building Acoustics


The new ift Laboratory for Building Acoustics in Rosenheimhas gained the maximum level of recognition among experts thanks to several years of experience. The laboratory has all the test benches necessary and the expert knowledge to analyse the significant issues pertaining to building acoustics under laboratory test conditions. Comprehensive and intelligently conceived and designed test facilities enable tests to be conducted and technical expertise and specialist opinions to be formulated expeditiously and flexibly.

Our experts are pleased to conduct even measurements on real objects in the course of support for construction from the quality assurance perspective or in case of an expert opinion required.


  • Airborne sound insulation

  • Transmitted impact sound

  • Flanking sound insulation

  • Characterisation of test elements by measuring dynamic rigidity, loss factor and sound impedance

  • Sound reduction of joints

  • Self-noise level


Building elements and shutters, e.g.

  • Windows

  • Doors

  • Industrial doors and gates

  • Facade

  • Roller shutter boxes

  • Rooflights

  • Window and facade profilesFenster- und Fassadenprofile

  • Internal and external walls

  • Roofs, ceilings, floor coatings, screeds, stairs

  • Wall outlet

  • Ventilation devices

  • IGU, LSG, Automotive glass

  • Panels

  • Composite thermal insulation systems

  • On-roof insulation

Small-parts like, e.g.

  • Joint seals (foam or sealing strips)

  • Sealants (rebate seals, floor seals)


  • With the help of gantry-type cranes (having a maximum load-bearing capacity of 24.6 tons in a spacious testing hall) even heavy components can be lifted quickly, safely, and reliably into the test benches for testing.

  • Our team also organises measurements on your object.

  • Manufacturing test openings of any size, type, and shape

  • This includes the acoustic reproduction of fittings with the construction elements being tested in practice.

  • Testing with parallel sampling for builders and planners is possible.

Test in the field of building accoustics may be carried out according to the following standards:
