While buying a diesel generator, people are usually worried about the high levels of noise. This is because there is a common notion that these equipment are noisy. However, this really depends on the frame of reference. If you&#;re comparing the noise generated from a gen-set to quiet place, then we have nothing to argue. Although, when compared to rocket launch noise a generator is actually pretty quiet. Read about how can you reduce diesel generator noise. However, we&#;re not here to debate, but we&#;re here to help.

The easiest way to reduce the noise from a generator is to increase the distance between yourself and the place where the diesel generator is installed. When the generator is moved further away, the energy is spread over a greater distance, and therefore there is a decrease in acoustic intensity.
According to the general rule, when you double the distance, you can reduce the noise by 6dB.
However, if you have bought a used diesel generator for sale, consult the previous user &#; what steps they were taking to reduce noise, which will help you take better decisions.
Solid surfaces restrict the transmission of noise by reflecting sound waves.
Installation of a generator in an industrial unit will ensure that the concrete walls act as acoustic barriers and limit the emanation of sound beyond that area. The achievement of exhaust noise reduction up to 10dB happens when the generator is inside standard generator canopies and enclosures. A bigger reduction of noise can happen when a portable generator is put in a custom-built enclosure.
Use acoustic fencing to create an extra barrier, if enclosures don&#;t help enough. Impermanent acoustic fencings are quick and effective solutions for construction assignments, utility networks as well as outdoor occasions. Installation of permanent and custom built acoustic screens will be helpful for larger installations.
Sometimes, simple maneuvers such as positioning the exhaust pipe vertically can help contain the noise level by ensuring that the sound is redirected upwards.
Use acoustic fencing to create an additional barrier if enclosures alone don&#;t do the trick.
Acoustic barriers reflect sounds waves and restrict noise only beyond the barrier. However, in order to reduce the noise, echo, and vibration within the generator enclosure/industrial room (also known as generator quiet box) you&#;ll need to insulate the space to absorb the sound.
Insulation involves lining hard surfaces with sound-absorbing materials or installing acoustic wall panels and tiles. Wall panels built from perforated steel are the usual choice for industrial applications, however, a variety of materials are also available and used.
Acoustic insulation, in addition to sound deflectors, can reduce sound of portable generators to a great extent
Limiting the noise at source is another great way to reduce noise from your generator.
Setting anti-vibration mounts underneath the generator removes vibrations and decreases noise transmission. Anti-vibration mounts are available in a lot of different options. Some examples of such mounts are rubber mounts, spring mounts, spring mounts, and dampers. Your choice will depend on the amount of noise you need to achieve.
Along with insulating vibrations at the generator base, fitting flexible joints between the generators and connecting systems can help reduce generator noise transmission to surrounding structures.
For industrial generators, the most effective way of reducing noise transmission is through attenuators. It is a device that enables large amounts of air to pass through it but limits the transmission of noise.
Air swirls between the splitters which absorb the sound and reduces the wavelength. It is worth noting that an attenuation system can reduce sound to something between 50-90dB. And according to the general rule, great noise reduction can happen in a loud generator with a larger attenuator.
The above tips to reduce generator noise are perfect when you already have a noisy generator. You can also contact us to know more about keeping your diesel generator quieter. For what it&#;s worth, we can also help you buy a standby generator that does not produce so much noise. Our team can even install the generator such that the noise caused by the exhaust pipes is greatly reduced, appropriately for a noise-free environment.

Most generators produce a significant level of noise, which makes it essential that you place your generator in an enclosure and sound proof the same using sound absorbing materials. to do so, you can seal the edges of the enclosure with foil tape or acoustic caulk. This will help make the seams airtight, and reduce the noise by up to 20 decibels.
While portable generators prove to be ideal for use in areas with irregular power outages, they are known to create sound waves ranging between 60 and 90 decibels, which is rather loud. In some cases, these generators can produce sounds of up to 100 decibels. Hence, when using a portable generator, one must be prepared for high fuel consumption as well as comparatively more noise.
A silent generator, contrary to popular belief, isn&#;t completely silent. It usually operates at a noise level of up to 65 decibels, which is equivalent to the sound produced during a normal conversation between two people.
It's no secret that diesel generators can generate not only power but also a lot of noise. Whatever your need for a generator is, it's safe to say that it can become annoying rather quickly. We have gathered some tips to reduce noise from your diesel generator. You can find and implement one or more to fit your needs.
The first way to reduce noise from a generator starts before you even buy one. The larger the generator, the more noise it is going to produce. If noise is a concern for you, be sure to get a generator that will fit your needs but is not too big.
You can also search for generators that advertise sound reduction. Technology is advancing to allow some generators to operate more quietly, but these generators are often more expensive.
A simple way to make your diesel generator less noisy is to have it installed farther away from where you are. Distance will reduce the amount of noise you hear.
You can also reduce some of the noise from a generator by positioning the exhaust end away from you. The exhaust end is where most of the sound comes from, so directing it away from where you will be will help it to be less bothersome.
Sound waves are vibrations, so when we can reduce vibrations, we reduce sound. Anti-vibration mounts can be set up underneath generators to reduce the number of sound waves. These mounts can be found made from rubber, springs, or dampers.
If mounts are not in the budget, you can still minimize the sound by placing the generator on a soft surface or even an anti-vibration rubber mat. These mats are common and available for a number of potentially noisy appliances.
Flexible joints between the generator and the connecting systems also allow for the reduction of vibrations.
Another option if the location of a permanent generator is non-negotiable is to have the generator enclosed. An industrial unit will reflect the sound waves and minimize the amount you will hear. Generator canopies or enclosures are great options to limit the sound.
If enclosures themselves do not create enough sound reduction, you can add acoustic insulation to the enclosure or room where the generator is stored. Insulation lines the walls with sound-absorbing materials, so less sound leaves the enclosure.
An acoustic fence is also an option to surround a generator canopy or enclosure. Such a fence is also a great option for generators that are not in permanent places, such as generators used in construction projects or for utility networks. Fences are quick to set up and provide an extra barrier between the generator and everyone's ears.
Your generator comes with a muffler, which is supposed to muffle the noise coming from the exhaust pipes. You can, however, replace the muffler with a larger and more quality one to muffle more of the noise. Be sure to research which mufflers will be compatible with your generator.
Water can be used to muffle the noise from your generator. If you put a large bucket of water lower than your generator, you can connect a hose to the exhaust pipe using a clamp. The other end of the hose goes into the bucket of water. You do not want water flowing backward to the exhaust pipe, so you can poke small holes in the hose to prevent this from happening.
The most effective way to reduce noise for large industrial generators is by using an attenuator. Attenuators limit the transmission of noise while they pass large amounts of air through them, swirling it, and then reducing the wavelength of the sound. Large attenuators can reduce noise by up to 90 dB.
