How To Make Your Generator Quiet As A Cricket? [Update 202] (1)Generators are turning out to be a necessity in life rather than a luxury in this power-stricken weather. If your locality is facing a power shortfall or power outages are running rampant due to weather and climatic factors, a generator is a must-have commodity.

Generators are the most common power backup sources as well as the primary power source in outdoor settings where grid power is not available. Although generators are becoming part and parcel of modern life there are many disadvantages to their use with the biggest shortcoming coming as their annoying sound that become a buzz killer over time.

Generators’ noise is not only disturbing for the family using it but also implicates the neighbors who are continuously annoyed by the sound of their neighbors’ generators.

So what should be done? Should you stop using the generator to soothe your ears? This is definitely not a reasonable solution and one should rather look for ways to reduce the generator noise.

Why Do Generators Produce Noise?

Generators produced to sound as a result of engine operation and an engine being a motorized device will always produce some sound. Similarly, the exhaust of the generator will lead to some noise produced by the passing of exhaust air through the pipe.

In a nutshell, the sound produced by a generator is a compulsory phenomenon and you can’t get rid of this sound by default no matter how efficient your generator engine is.

But this doesn’t mean you have to continually listen to the annoying buzz as you can look for ways to block the sound from reaching your ear.

For that purpose, go through our review article till the end to know some useful tips for reducing the sound level of your generator.

How To Make Your Generator Quiet As Cricket?

Given below are the 5 tips for making your generator as quiet as cricket

  • Building a soundproof box
  • Using a muffler
  • Using rubber feet
  • Using a baffle box
  • Putting the generator away from the living area

Let us now discuss these tips one by one in detail.

  • Building A Soundproof Box:

If you are using a heavy-duty generator in your home or office that doesn’t need to move between places then building a soundproof generator box will be the best bet. This method is not good for portable generators because a soundproof box will make the product heavier and difficult to transport there this method will be more suited to heavyweight generators running at a fixed position.

A soundproof box is easily made at home using the Plywood racks and insulation material easily found at retail shops. You can use two layers of insulation media separated by an isolating material to surround your generator with a rectangular box around all four sides. This soundproof box is insulated, and sealed and has a space for a ventilation duct to let the generator exhaust leave safely from the box.

The soundproof box will work most effectively for making the generator noise close to negligible and giving you an efficient engine performance without annoyance or disturbance.

  • Using A Muffler:

If you don’t have enough technical expertise to make a soundproof box or don’t have enough time to go make one then you should try our second solution for reducing the generator noise to make it as quiet as a cricket. This tip involves using a muffler for reducing the sound produced by the generator engine.

Almost all engines are coming with a built-in muffler and the task assigned to this muffler is to reduce the sound that is to muffle it. But most of the time, the pre-installed muffler is not fit or good enough to perfectly muffle the noise. In those cases, you can install a new and bigger muffler to cut the generator sound and make it quiet.

Muffler will not remove the generator sound altogether but will reduce it to a certain extent. The use of a muffler will prevent the sound produced from the exhaust pipe and thus the engine sound will be left untouched. For reducing the engine noise you have to combine the use of a muffler with other tips to have a generator as quiet as a cricket.

  • Using A Baffle Box:

If a muffler alone doesn’t satisfy your needs you can make a baffle box and this is almost similar to the making of a soundproof box. The soundproof box is meant to insulate all kinds of noise while the purpose of the baffle box is to filter the airborne noise that is produced by the passing gasses from the exhaust pipe of the generator.

Similar to the use of muffle, the baffle box is not aimed at making a generator quiet but will play its part in reducing the extent of sound produced. Baffle boxes and mufflers are nearly similar in their purpose and therefore using either one of them will do the job for you.

You can build the baffle box and don’t have to screw it at the bottom. This means you can easily put it on your generator anytime and anywhere unlike a soundproof box that is sealed from all four sides.

  • Using Rubber Feet:

Until now you have seen the way to reduce airborne sound and insulate the sound in a soundproof box but there are other types of sound produced by the working of a generator.

For making a generator as quiet as a cricket you need to eliminate all of these possible sound sources. So, if you are curious about how to make a generator as quiet as a cricket read our next 2 solutions to make it quieter.

Airborne sound will be controlled by the muffler or the baffle box and for controlling the vibrations of the generator you can make use of the rubber feet to eliminate the vibrating sound coming from your generator.

Rubber feet will considerably reduce the generator noise and this will be sharply evident to the ears. This is because sound travels faster in solids and the generator in direct contact with the ground will be producing more noise than a generator put on rubber feet. If you don’t like to go with rubber feet you can use a soundproof mat as an alternative to these rubber feet.

  • Putting The Generator Away From Living Area:

If after trying all of the above-mentioned tips, your generator still produces a considerable degree of noise that is evidently heard by you, changing the position of your generator will be a helpful solution too. You should try to place your generator as far as possible from you. Therefore, put it away from the living room and get rid of its annoying buzz.


In this article review, we have provided you with some useful tips for reducing the sound produced by the working of your generator. These tips or methods will reduce the noise to varying degrees and for making the generator as quiet as cricket you should try to employ all of these tips at the same time to enjoy the maximum benefits. All of these solutions will help you in controlling the generator sound and thus you will be free from the generator noise.

What can change the sound of a generator? ›

E.g; buildings, walls and signage are common factors that change the sound field. Obstacles within the sound transmission path will partially reflect, absorb or transmit the sound. It is important to study site conditions and know local noise laws before starting a generator project.

Where does most of the noise come from on a generator? ›

Noise from “portable” generators comes primarily from two sources, the engine block and the exhaust system. With an air cooled engine there is little you can do about blocking noise. Some engines can have a larger muffler attached or make other changes to the exhaust system.
