Acoustic material parameters
Our services
We determine the acoustic material parameters absorption coefficient, dissipation factor and transmission loss, enabling you to detect any acoustic weaknesses in a material while it is still at the development stage and then optimize the material as necessary. We can also provide a detailed analysis of which material is best suited for which application. For example, materials with a high absorption coefficient are used for noise reduction in buildings whereas materials with a high dissipation factor are used for vibration damping. Noise-absorbing elements with a high transmission loss prevent the transmission of sound energy.
Your advantages
- We assist by providing you with comprehensive information and advice about the acoustic properties of materials. You can utilize this expertise in the development of new products.
- Our measurements enable you to identify acoustic weaknesses in a material while it is still at the development stage. You can therefore implement appropriate optimization measures early on in the process.
Our strengths
We offer close collaboration in the strategically important and sensitive field of material development. Our presence in the CHEMPARK allows us to react quickly and flexibly.

Absorption coefficient:
Materials with a high absorption coefficient are used for noise reduction, e.g. for roof linings in cars or acoustic ceilings in reverberating rooms.
Dissipation factor:
Materials with a high dissipation factor are used for general vibration damping in the form of coatings for components, e.g. automotive floor assemblies or housings for domestic appliances such as dish washers.
Transmission loss:
Noise absorption (high transmission loss) prevents the transmission of sound energy, e.g. through doors, walls and ceilings.
