How to Make Your Generator Quiet as A Cricket?

A generator can be a lifesaver in case of an emergency or if you live in a remote community where regular power supply is not always feasible.

But then again, a very loud unit can be more of a hassle than help, and you will have to look for ways to minimize it.

Here we shared some of the best ways to silence your generator without compromising its performance.

Factors Behind Loud Generator Noise:

  • Generator Technology

Some of the portable generators that create electrical energy through an engine, make a lot of noise even if they are one of the expensive models. The more inexpensive a generator is, the higher the sound will be.  On the other hand, a generator with 60 to 70 decibels will be as loud as a vacuum cleaner or dishwater. Although this sound isn’t too loud for a little while, for a long period of time, the noise can be overwhelming.

In other cases, a generator may begin to make a lot more noise while it is wearing down or requires a repair.

  • Vibration

Much of the noise that a generator produces comes from the vibration. A vibration dampening material can be used to minimize the noise. One way to do so is to add a rubber washer to the screws that secure the engine to the frame. This helps absorb some of the vibration and the noise.

  • Generator Placement

The placement of the generator is very important when it comes to reducing the noise level of the generator. The type of material on which you place the generator is what matters the most. When placed on a metal bench, the noise would be much higher. So surfaces that act like amplifiers should be avoided.

Fairly hard surfaces like wood, metal. Wood or concrete are also a big no for generators because such surfaces increase the vibrations and in the end increase the level of noise. So, the generator should instead be placed on soft and stable ground like flat soil. This will help the ground to absorb the vibrations.

  • Position the Exhaust Pipes Vertically

The placement of the exhaust pipes of a generator is considerably a significant factor. When turned horizontally, the air is blown outside. This means that the noise is being blown horizontally as well. But if you set the pipes vertically, there will be less noise and it won’t be as loud as it was.

  • Add a Sound Deflector

A sound deflector is another medium of effectively reducing noise levels of the generators. A sound deflector device deflects away noise from specific areas. In the areas where you don’t want to hear the noises come from, this device will make those areas quieter or reduce any noises made.

But what it doesn’t do is make the generator itself quieter or reduce any of the noise it makes. Primarily, it helps to retain the noise away from you.

  • Upgrade the Exhaust Muffler

The muffler is another mechanical part that is responsible for causing annoying noise in the generator. Mufflers are meant to reduce the noise of the machine. With a properly functioning generator, a muffler that malfunctions could create havoc.

  • Use Water Trick

There’s a water bucket trick that you can play in order to dampen the noise level of the generator produced by the exhaust pipe. Simply connect the hose pipe to the exhaust of the generator and put the other end in a bucket of water. But in order to prevent the water from getting into the generator, creating a small hole at the highpoint of the hose pipe should work.

  • Build Enclosure for the Generator

Building an enclosure or a soundproof cage around the generator would be a good option. The caging helps to muffle noise levels.

  • Position the Generator Far Away

While going camping, don’t forget to place your generator a minimum of 20 feet away from the camp you’re staying at. You must also ensure that the  exhaust pipe is facing away from you.

  • Use Rubber Feet

Covering the feet of the generator with rubber is another method to lower the sounds produced by a generator. Similarly, another way to reduce noise pollution produced by a generator is to put a soundproof mat underneath it. Other options like installing anti vibration pads or a rubber mat is also another efficient technique to make your generator noiseless.


1. Is it possible to make a generator muffler at home?

Ans: There are many ways to get creative while muffling your generator at home. You can either make an automotive muffler, use a generator muffler silencer, or simply build a plywood box to encase the generator

2. Why are generators so loud?

Ans: The sound produced by generators can be measured by calculating the sound in decibels from a range of about seven meters. They are reasonably loud for the kind of power they produce. A high sound of 85 decibels isn’t something surprising for a generator that produces around 50 kilowatts.

3. Can you put a silencer on a generator?

Ans: Absolutely. You can definitely use an automotive muffler to muffle the sound of your portable generator. Although it’s not the most effective mode of noise reduction, however, it successfully does reduce 10 to 15 decibels. A few tools, some creativity and an automotive muffler is all you’ll need
