Absorption – Effective sound reduction through sound-absorbing materials
The term absorption plays a central role in sound insulation and room acoustics. Absorption describes the ability of a material to absorb sound waves and minimise their reflection. This reduces reverberation and significantly improves the acoustic environment.
How does sound absorption work?
Sound waves hit a surface and can either be reflected, absorbed or transmitted. Sound-absorbing materials, such as acoustic foams, non-woven fabrics or porous structures, convert sound energy into heat and prevent unpleasant sound feedback.
Areas of application for sound-absorbing materials
Absorption materials are used specifically for noise reduction and sound insulation in various areas:
- Machine and vehicle insulation – sound absorption in bonnets, machine housings or technical equipment
- Improving room acoustics – use in offices, conference rooms, schools and daycare centres to reduce reverberation and speech noise
- Industrial and production facilities – reduction of noise emissions to comply with noise protection guidelines
- Building acoustics – optimisation of the acoustic properties of buildings through sound-absorbing walls and ceilings
