Decibel (dB) – The unit of measurement for sound and noise
Sound levels are measured in decibels (dB) and indicate how loud a noise is. From quiet background music to loud machinery or traffic noise – the volume of a noise affects our well-being and can be harmful to our health at high levels. In the field of sound insulation and acoustics, reducing the decibel value through suitable sound insulation and sound absorption is crucial.
How does the decibel scale work?
The decibel scale is logarithmic, which means that even a small change has a big impact:
- 10 dB – almost inaudible (rustling leaves)
- 40 dB – quiet environment (office, quiet flat)
- 60 dB – normal conversation volume
- 80 dB – busy road (continuous noise can be harmful to health)
- 100 dB – jackhammer (hearing damage possible with prolonged exposure)
- 120 dB – pain threshold (airplane taking off nearby)
Sound insulation – effectively reducing decibel levels
Depending on the environment and application, various measures can help to reduce noise by several decibels:
✔ Sound insulation – prevents sound transmission between rooms or building components
✔ Sound absorption – Reduces reverberation and improves room acoustics
✔ Structure-borne sound insulation – Minimises vibrations in machines or vehicles
Soundproofing solutions from Cellofoam
Cellofoam offers a wide range of soundproofing materials that help to effectively reduce decibel levels:
✔ Acoustic foams and acoustic non-wovens for walls, ceilings and technical
applications
✔ Noise protection solutions for machines and vehicles to minimise
operating noise
✔ Heavy foil for sound insulation
✔ Precisely cut to size for easy installation of parts
✔ Products for improving room acoustics in many colours and shapes
Conclusion
A reduction of just 3 dB halves the perceived volume – with the right soundproofing materials from Cellofoam, noise levels can be specifically reduced to create a more pleasant environment.
