The working procedures and internal regulations of the Fraunhofer-Institute of Building Physics (IBP) guarantee a high quality of testing. This is explicity confirmed by the German institution DEUTSCHER AKKREDITIERUNGSRAT (DAR).

Our testing laboratory of building acoustics and environmental noise has been accredited at the highest level according to DIN EN ISO/IEC 17025. Due to this so-called FLEXIBLE accreditation we are authorized to adapt testing methods to the state of the art as well as to develop and to apply new methods.

During the last years more than 500 clients profit by this accreditation in many different ways: The high degree of testing competence is regularly checked and confirmed by impartial experts. Therefore, the reliability and confidentiality of the results can be guaranteed. Each of our testing reports will be regarded as a certificate with excellent reputation. The scope of our flexible accreditation comprises:

Building Acoustics

Determination of acoustic quantities of building components, structures and materials by laboratory or field measurement

Noise of water supply valves, of other equipment of water installations, of exemplary installations, of waste water systems and installation walls by laboratory or field measurement

Determination of acoustic quantities of noise barriers


Environmental Noise

Determination of noise emission (sources, effects) by traffic, factories and plants, leisure and sport facilities as well as at work-places

Determination of radiated sound power and acoustic diagnosis of machines, appliances, equipment

Determination of vibrations and tremors (sources, effects)

Examination of measures for noise and vibration control
