Tips to Reduce Noise Level Your Diesel Generators


When purchasing diesel generators, people are usually concerned about high levels of noise. This is because there is a common belief that this device is noisy. However, it really depends on the frame of reference. If you are comparing the noise generated from the diesel generator in a quiet place, then it is quite impossible as a generator makes noise in operation. We cannot shut down the noise of the generator but we can definitely try to reduce it with the help of silent diesel generator canopies.

Labor exposure to excessive or repetitive noise over a long period of time can result in hearing loss. Producing an excessive source of noise in an environment can be potentially dangerous, as well as unpleasant for nearby commercial tenants and residents. High noise control measures have been taken at national and local levels to maintain both security and peace of mind.

Noise control systems consist of three basic fundamentals: sound, path, and receiver. Before a solution to a complex noise problem can be devised, the major source of noise pollution must be known, the characteristics of the transmission path must be explored and an acceptable level of noise is established.

Tips to Making Your Diesel Generator Quietest

Diesel Generators not covered by enclosure or close-fit canopy are thrust. So loud that depending on the size of the engine, working within 7 meters will mean that you won’t hear properly. Local authorities have their own noise level lead tests to determine what the sound level is that the plant is located near domestic homes.

With the help of these five ways, you can reduce diesel generator noise.

●      Distance of Generator

The easiest way to reduce noise from a GenSet is to increase the distance between yourself and the space to install your diesel generator. When the generator is moved further away, the energy is transmitted over a greater distance and hence there is a decrease in acoustic intensity. As a general rule, when you double the distance, you can reduce the noise by up to 6 dB. You cannot shut down the noise of your diesel generator, but you can definitely adopt different solutions for it. And live a comfortable life.

●      Acoustic Barriers

The solid surface reduces the transmission of noise by stopping the transmission of sound waves.

The installation of a diesel generator in an industrial unit will ensure that concrete walls act as acoustic barriers and limit the emission of sound beyond that area. Noise is reduced by up to 10 dB when the GenSet is inside the gentent and enclosures. When generators are inserted into custom-built enclosures, a large noise reduction can occur.

If additional assistance is not enough, use an acoustic fence to create an additional barrier. Important acoustic constructions are quick and effective solutions for construction work, utility networks as well as outdoor opportunities. Installation of permanent and custom-made acoustic screens will be helpful for larger installations. If enclosures are not used alone, use acoustic fences to create additional barriers.

●      Acoustic Insulation

Acoustic interrupts reflect sounds and prevent noise beyond mere inhibition. However, to reduce noise, echo, and vibration within the diesel generator enclosure / industrial room, you will need to insulate the location to absorb the sound. Insulation includes lining hard surfaces with sound-absorbing materials or installing acoustic wall panels and tiles. Wall panels manufactured from perforated steel are a general choice for industrial applications, however, a wide variety of materials are also available and used.

●      Anti Vibration Mounts facility

Restricting the noise at the root is another great way to reduce noise from your diesel generator.

Installing an anti-vibration mount under the generator removes vibration and reduces noise transmission. Anti-vibration mounts are available in lots of different options. Some parts of such mounts is rubber mounts, spring mounts, spring mounts, and dampers mounts. Your choice will depend on the noise you need to receive.

With the oscillating vibration at the diesel GenSet base, fitting flexible joints between the generator and the connecting system reduces noise transmission to surrounding structures.

●      Attenuators

For industrial diesel generators, the most efficient method of reducing noise transmission is through attenuators. It is a device that releases large quantities of air to pass through it but limits the synchromesh of noise. Air records between the splitters which absorb the sound and decreases the wavelength. It is worth noting that an attenuation system can reduce sound to something between 50 dB to 90 dB. And according to the common rule, high noise reduction can happen with a larger attenuator.


Everyone has started using the diesel generator but all of them are disturbed by the noise emanating from the diesel GenSet and in search of a very quiet diesel generator. You can silent  your generator using the generator canopy with your diesel generator.

I hope that after reading this blog, you will understand the use of silent canopy to reduce the sound of a diesel generator. If you would like more information related to the pollution by Diesel Generator and generator service, our EO Energy team is always here to help you and solve your problem.
