1. Construct a wall around the Generator

The easiest and simplest way is to construct a wall of cinder blocks around the generator. Make sure there is some room between the wall and the generator. You can leave a gap of at least 6 inches from the sides and above. The blocks will absorb maximum sound waves.

2. Use a vibration absorber in the motor

A generator’s vibrations are mostly responsible for its loudness. Vibration-absorbing material can be added to the motor of the generator to lessen that noise. Observe the screws holding the motor to the frame, and you will see that the silicone washers between the bolts and the frame are probably already present.

3. Use water as your generator Muffler

If the thought of replacing your muffler seems like too much work, you can also use water. But there are some changes that you must have to make first. A 5-gallon pail of water, a hose, and a clamp to fasten the nozzle to the exhaust system are needed for the alteration. Make sure to set the generator up higher than the water bucket.

The water shouldn’t be going back into the exhaust pipe of your generator. To be extra cautious about preventing water from backing up, you can also make a few tiny holes in the hose. It’s not too difficult to set up. By use of your clamp, attach the hose to the exhaust pipe. Next, insert the hose’s other end into the water-filled bucket. In this way, the sound of the generator’s exhaust will be muffled by the water.

4. Place a Rubber Mat underneath the Generator

Placing a high-quality, fluffy rubber mat underneath the generator will make your generator less noisy. However, it works slightly differently as the rubber mat absorbs maximum vibrations. You can buy this rubber mat online also.

5. Try changing your generator Muffler

Installing a bigger replacement muffler is one of the most widely used methods for making generators quieter. The purpose of a muffler is to mute the noise produced by the exhaust pipes connected to the generator’s motor.

There are porous tubes in the motor that are located inside the muffler and are intended to redirect sound waves from the motor and reduce noise that eventually leaves the exhaust pipe.

The motor itself is the loudest component of the generator. You will observe that there is a decrease of 10–12 decibels by upgrading the muffler’s quality.

6. Make an Acoustic enclosure around the generator

Another approach is to build an acoustic enclosure similar to making deflectors. Deflectors actually function effectively same as this enclosure. The barrier will contain the sound waves and significantly reduce the noise levels produced by the generator.

The best thing about an acoustic enclosure is that it is considered portable. Another excellent feature is that these enclosures are easy to make and also available on market.

7. Keep the distance between the generator and your living space

The distance between the generator and your living space is the most important thing. One of the most crucial elements is ensuring that your home or campsite remains quiet when using this powerful machine.

There are several factors that you must have to consider before setting your generator to a far-off place. For instance, you must certainly consider your neighbors. You don’t want your generator to be too loud so that it disturbs other people.

8. Try an Inverter Generator

This is the age of technology and with the passage of time, this technology upgrades. So, if you are still living old-fashioned you should change, otherwise, you are harming both the environment and yourself. Instead, switch to a new, environment-friendly ultra-quiet inverter generator that consumes less gasoline and produces less noise while providing more power.

The generator itself should be the first place of consideration while using it, the generator’s exhaust ends in particular. Placing the generator with this facing side away from your home or camping site is always a good idea.

You may even direct the exhaust pipes of some generator models to aim upward and toward the sky. You will be kept away from the noise generated by the exhaust in either of these settings.

10. Buy a quiet generator
