Why Reducing Generator Noise Matters
Generator noise is a common concern. Excessive noise disturbs local communities and nearby businesses, and on-site teams. It also heightens complaints and environmental concerns.
Managing generator noise supports smooth site operations. It protects workforce wellbeing, reduces disruption to others, and helps you meet environmental standards.
Below are proven strategies to reduce generator noise without compromising performance or compliance.
Choose Sound-Attenuated Generator Units
At MEMS, ultra-low-noise equipment is standard. Each generator operates in a custom-designed sound-attenuating enclosure, which means it is built to block and absorb noise, helping to control sound levels while maintaining maximum reliability.

Exhaust Noise: MEMS Sound Shield
Advancements in generator design have reduced engine noise significantly. Exhaust noise remains a consideration at many sites and often requires additional control.
The MEMS Sound Shield provides a simple solution. It installs quickly and is suited to sites where extra noise reduction is required.
The MEMS Sound Shield absorbs sound from the generator exhaust while withstanding high exhaust temperatures. It maintains proper ventilation, supporting engine efficiency and reliable performance.
Benefits:
- Quieter operation, even in sensitive environments
- Robust performance without overheating
- Quick and easy installation on hire units
Use Acoustic Barriers for Extra Control
Some environments, particularly built-up areas, can amplify noise due to reflective surfaces. Portable acoustic barriers or MEMS Acoustic Curtains provide an extra layer of sound control, containing noise across the site within a generator enclosure.
Tips for maximum effectiveness:
- Install barriers close to the generator
- Position to block direct sound paths.
- Combine with strategic generator placement for optimal results
Minimise Runtime, Maximise Silence
The most effective noise reduction comes from operating the generator only when necessary. Hybrid power systems, which combine a generator with a battery energy storage system (BESS), allow power to be supplied during low-demand periods.
Advantages:
- Reduced noise exposure
- Lower fuel consumption
- Decreased emission output
Quieter Operation & Improved Efficiency with Remote Cooling System
Fixed cooling fans have a considerable impact to generator noise and efficiency when running at fixed speeds.
Variable-speed remote cooling reduces noise by adjusting the fan speed to match the engine’s temperature demand. This allows the generator to operate more quietly while maintaining effective cooling and increased performance.
This approach supports:
- Reduced fan noise during normal operation.
- Improved efficiency under part-load demand.
- Tighter control of cooling without overworking the system.
Smart Generator Placement
Noise levels are greatly influenced by where the generator is positioned. Careful site planning reduces disruption:
- Keep generators away from offices, residential buildings, and public areas
- Use existing structures, earth banks, or fences as natural sound barriers
- Avoid locations where sound waves will reflect toward occupied areas
A site assessment before delivery ensures the best location for quiet, efficient operation.
