When renting a diesel generator, everyone is normally worried about the high levels of noise. This thought happens because these diesel generators are loud in every industry and the hospitality sector. Then, how to reduce noise from a diesel generator? This article will guide you to some tips that will help you reduce noise from your diesel generator.
5 Tips to Reduce Noise from Your Diesel Generator
1. Use Acoustic Enclosure
Every businessman in the industry will ask this common question: How to reduce noise from a diesel generator? Because nowadays, diesel generators are mandatory in every industry.
This is the first step to reduce noise from your diesel generator. The acoustic enclosure can reduce and lower the actual noise of the generator. Diesel generators with acoustic enclosures are the best option for industry. Acoustic enclosure structured as wall panels built from perforated steel. It can reduce 50% of the sound coming from the generator.
2. Use an anti-vibration mount to reduce the noise level of the diesel generator.
The limitation of the noise is another best tip to reduce noise from your diesel generator.
Setting anti-vibration mounts certainly removes vibrations and decreases noise transmission. Anti-vibration mounts have many options, like rubber assemblies, spring assemblies, spring mounts, and dampers.
The amount of noise you need to achieve depends on your choice.
In combination with insulation vibrations on the generator base, fitting flexible joints between generators and connection systems reduces the noise transfer to the environment.
3. Attenuators
The most effective way to reduce noise transmission for industrial generators is with attenuators.
It is a device that allows a large amount of air but limits noise transmission. Air flows between sound-absorbing splitters, and the wavelength is reduced.
Note that an attenuation system can reduce the sound to between 50-90 dB. And a big reduction in noise can occur with a larger attenuator under the general principle.
4. Generators with Noise Levels Less than 75 dB
The generator creates more noise levels, which is the reality, but there is always a solution. Generators with a noise level below 75 dB can typically be applied in commercial areas because the demand for output is high. So every zone of the generator has different noise level limitations.
The maximum permissible noise level for new generators with a rating of up to 1000 KVA is 75 dB, according to CPCB guidelines. So if you are renting a generator in Chennai, make sure to follow this guideline.
5. Install Proper Exhaust Mufflers
One of the primary sources of noise in a diesel generator is the exhaust system. Installing a high-quality industrial-grade exhaust muffler or silencer significantly reduces the noise produced during operation. Mufflers work by absorbing and deflecting sound waves through a series of chambers and materials that cancel out noise.
There are three types of mufflers: resistive, absorptive, and reactive. The choice depends on your generator’s size and usage area. For commercial or residential zones, reactive or combination mufflers are ideal, as they offer maximum noise reduction without affecting performance.
Regular maintenance of the exhaust system also ensures that no damage or leaks increase sound output over time.
