Background noise – the basis for effective sound insulation in machines and vehicles

Background noise refers to the constant, uniform noise level present in a given environment. In technical acoustics, background noise is often perceived as ambient noise caused by machines, motors or environmental sounds.

A high background noise level can lead to acoustic stress, concentration problems and increased noise pollution. Especially in industry, mechanical engineering and automotive engineering, it is important to minimise the background noise level in order to create a pleasant and safe working environment.


How is background noise created?

Background noise is composed of various sound sources:
 

  • Machinery and production noise – continuous noise from engines, pumps or ventilation systems
  • Vehicle acoustics – continuous noise from chassis, air conditioning systems and gearboxes
  • Airborne and structure-borne noise – sound transmission through solid components or in rooms
  • Environmental noise – disturbing noise from road traffic, industrial plants or wind turbines
     

Depending on the frequency range (low-frequency or high-frequency), different sound insulation measures must be taken.

Soundproofing solutions to reduce background noise

To reduce background noise levels, Cellofoam offers customised soundproofing solutions for various applications:

✔ Heavy-duty foils & anti-drumming mats
    Dampen low-frequency engine & machine vibrations

✔ Acoustic foams & absorber panels
    Minimise reverberation & airborne noise in interior spaces

✔ Insulation materials for automotive engineering
    Reduce driving noise & improve driving comfort

✔ Sound-absorbing cladding
    Optimise acoustics in production halls & machine rooms

✔ Mechanical engineering & industry
    Reduce continuous noise levels in production facilities

✔ Rail vehicles
    Noise insulation for engines, chassis & air conditioning systems

✔ Ventilation & HVAC technology
    Optimise acoustics in heat pumps & ventilation systems

Why is reducing background noise important?

✔ Less noise pollution – improved working conditions in industry and automotive engineering

✔ Optimisation of speech intelligibility – clear communication in machine and vehicle cabins

✔ Increased product quality – less disturbing noise in high-end vehicles and devices

✔ Compliance with noise protection regulations – reduction of continuous noise levels in accordance with legal requirements

Conclusion

A high background noise level can significantly increase noise pollution in machines, vehicles and industrial plants. 

Cellofoam's high-quality sound insulation solutions effectively reduce airborne and structure-borne noise, creating a more pleasant acoustic environment and a quieter atmosphere. This not only has a positive effect on the service life of technical components, but also on people's well-being and health: concentration, speech intelligibility and stress resistance are improved, while fatigue and sensory overload are significantly reduced.
