At PowerGen Australia, we provide high-quality, customised generator solutions to meet the diverse needs of our clients across Sydney and beyond.
One concept that often arises in discussions with our clients—especially in residential, commercial, and event settings—is generator attenuation.
In simple terms, this refers to the reduction of noise generated by a power generator.
Let’s break down what attenuation is, why it’s important, and how we help our clients manage it effectively.
What Is Generator Attenuation?
Generator attenuation is the process of reducing the sound levels produced by a generator during operation. Generators, especially diesel-powered units, can emit significant noise—sometimes exceeding 100 decibels (dB), which is comparable to a jackhammer or chainsaw.
Attenuation techniques are used to bring those sound levels down to acceptable or legally required levels, typically between 65–75 dB at a distance of 7 metres, depending on the application and local council regulations.
Why Is Generator Attenuation Important?
- Compliance with Local Noise Regulations
Councils across Sydney and NSW have strict noise level regulations, especially in residential or built-up areas. Whether you’re using a generator on a construction site, in a hospital, or at an outdoor event, failing to meet these limits can result in fines or project delays. - Neighbour and Community Relations
Minimising generator noise is essential to maintaining a positive relationship with nearby residents, businesses, and the general public. - Workplace Health & Safety
Prolonged exposure to loud noise can damage hearing and lead to other health and safety concerns. Attenuated generators create a safer environment for workers and visitors. - Enhanced Comfort and Productivity
For indoor applications like data centres, hospitals, or offices, reduced generator noise ensures a more comfortable and productive working environment.
How Is Generator Attenuation Achieved?
At PowerGen Australia, we offer several proven attenuation solutions:
- Acoustic Enclosures
These are soundproof housings that surround the generator. Our enclosures are designed with special acoustic insulation and baffle systems to trap and absorb sound while still allowing ventilation. - Sound Attenuated Canopies
For mobile and outdoor applications, these canopies offer weather protection while significantly reducing sound output. - Exhaust Mufflers and Silencers
One of the noisiest parts of a generator is the exhaust. High-performance mufflers and silencers can reduce exhaust noise by up to 35 dB. - Customised Acoustic Rooms or Containers
For larger or stationary generator installations, we design and construct full acoustic rooms or modified shipping containers that meet precise attenuation requirements. - Anti-Vibration Mounts
These help reduce the structural transmission of sound and vibration to surrounding areas.
