The development, product launch, and quality assurance of construction materials, building components, and technical products require reliable acoustic testing. For manufacturers, planners in the construction sector, and industrial applications, we perform standard-compliant laboratory tests as well as on-site measurements to determine acoustic properties.
Müller-BBM stands for objective measurements and robust calculations based on advanced measurement technology, powerful computational methods, and specialised test rigs. In our facilities, we carry out type testing and initial type testing in accordance with national and international standards, ensuring the acoustic performance of materials and components. Through on-site acoustic measurements, we verify sound insulation in newly constructed buildings as well as in existing structures.
We also see ourselves as a technical sparring partner: we develop measurement concepts, integrate new measurement techniques, and support the planning and construction of acoustic test rigs and measurement facilities.
Our laboratory tests and on-site acoustic measurements cover a wide range of acoustic parameters and enable a reliable assessment of materials, components, and in-situ building conditions:
In our wall test facility in accordance with DIN EN ISO 10140-5, we investigate airborne sound insulation of wall and roof constructions, doors, façade elements, noise barriers, and interior and exterior components of vehicles.
Measured parameters include:
Evaluation is carried out in accordance with DIN EN ISO 717-1 and application-specific regulations such as ZTV-ING, DIN EN 1793-2, DB-RiL 804.5501, or DIN EN 16272-2.
In our intensity test facility, we conduct precise sound insulation measurements using sound intensity methods in accordance with DIN EN ISO 15186-1 and determine sound power levels according to DIN EN ISO 9614-2.
For high-resolution surface scans, we use robot-assisted measurement systems.
The floor test facility is used to analyse the reduction of impact sound through floor constructions such as screeds and floor coverings. Measurements are carried out on a standardised massive reference floor in accordance with DIN EN ISO 10140-5.
In our material testing laboratory, we determine acoustic and structural-dynamic properties of materials and components.
These include:
Our reverberation room enables precise measurements in a diffuse sound field for the determination of sound absorption, sound power, and insertion loss in accordance with standards.
Typical measurements include:
For smaller samples (approx. 1 m²), our reverberation chamber is available. It allows comparative testing under diffuse field conditions, particularly suitable for prototype development and project-specific material selection.
In addition to laboratory testing, we provide comprehensive on-site acoustic measurements:

Accredited testing and calibration laboratories are required to maintain an up-to-date list of the standards for which they are accredited. These standards are typically specified in the annex to the accreditation certificate. Within the scope of flexible accreditation, different editions of a standard may be applied, provided that the respective version has been internally verified.
An overview of the standards currently applied in our laboratories, along with their respective verification status, can be found here.
