Containers equipped with power generators are indispensable in many industries – they provide energy independence on construction sites, in ports, at outdoor events, or in locations without a permanent power connection. Unfortunately, generator operation involves high noise levels, which can be disturbing to the surroundings and, in some cases, even lead to violations of noise regulations. Therefore, soundproofing a container with a generator becomes a necessity both for practical and legal reasons.
Why are generators so noisy?
Noise generated by power generators has several sources:
Combustion engine – emits both mechanical and combustion sounds.
Exhaust system – vibrations and exhaust gases cause high noise levels.
Ventilation and cooling – generators require intensive airflow, which generates additional noise.
Vibrations transmitted to the structure – container resonance amplifies the perceived noise.
Methods of soundproofing a generator container
Acoustic wall insulation The most common solution is the installation of soundproof mats, acoustic panels, or special sound-absorbing boards on the container’s internal walls. These reduce reverberation and absorb part of the acoustic energy.
Acoustic silencers on the exhaust system A properly selected silencer can reduce even several decibels of exhaust noise. This is one of the key solutions in noise reduction.
Ventilation system with acoustic ducts A generator must be cooled, so it cannot be completely sealed off. The solution is ventilation ducts shaped like a labyrinth, lined with sound-absorbing materials. They dampen the noise while allowing proper airflow.
Anti-vibration flooring Using vibration isolators and special pads under the generator limits vibration transmission to the container’s structure, thus reducing resonance.
Acoustic doors and seals Leaks are the “weak points” of any insulation. Sealed container doors with additional sound-absorbing layers significantly improve acoustic comfort.
Soundproof cabins For particularly demanding projects, additional enclosures around the generator – so-called acoustic cabins – are used. They act as a second sound barrier.
Conclusion
Effective soundproofing of containers with generators requires a combination of several solutions: from acoustic insulation and silencers to anti-vibration systems and specialized cabins. This ensures compliance with noise regulations and provides comfort for both workers and the environment.
