Attenuation – Effective technical sound insulation for machines and vehicles
Attenuation plays a central role in technical sound insulation, especially in machines, vehicles, heat pumps and industrial plants. It describes the ability of a material or system to reduce vibrations and noise by converting mechanical energy into heat.
How does attenuation work?
Sound and vibrations propagate through air (airborne sound) or solid materials (structure-borne sound). To reduce sound transmission, sound-absorbing, open-cell materials such as foams or PES nonwovens are used, which:
✔ Absorb sound energy and convert it into heat
✔ Prevent airborne sound from propagating
Cellofoam damping materials for machines and vehicles
Cellofoam offers specially developed soundproofing materials for effective vibration and noise damping:
✔ Acoustic foams – absorb airborne sound for a quieter environment
✔ Acoustic fleeces – for ideal sound absorption at medium and high frequencies
✔ Multi-layer sound insulation panels – Combine sound insulation and damping for optimum noise protection
✔ Heavy plastic films & heavy bitumen films – Increase the mass of components and reduce sound transmission
✔ Anti-drumming mats & elastomers – Dampen vibrations and minimise structure-borne noise in machines and vehicles

Why is effective attenuation important?
✔ Noise reduction & increased comfort – quieter machines, vehicles & working environments
✔ Protection of sensitive components – less vibration, less wear, longer service life
✔ Compliance with noise protection guidelines – less noise emissions in industry & vehicle construction
✔ Increased energy efficiency – prevention of vibration losses in technical systems
✔ Reduction of reverberation – improved concentration, better speech intelligibility and communication
Conclusion
Targeted attenuation is essential for minimising noise, vibrations and structure-borne sound in machines and vehicles. Cellofoam's high-quality attenuation materials can be used to optimise technical systems, reduce noise and extend the service life of components.
In addition, well-designed room acoustics contribute significantly to improving speech intelligibility, concentration and general well-being – whether in work environments, educational institutions or public spaces.
