Key Takeaways

  1. Consider purchasing a generator that fits your power needs, as more powerful generators tend to be louder.
  2. Face the generator exhaust pipes away from your campsite or point them upward.
  3. Use a generator with a built-in inverter for quieter operation.
  4. Place the generator on a soft surface to absorb sound.
  5. Use sound deflectors or build an acoustic enclosure or muffler box to reduce noise.

It’s understandable that you’d like a break from the constant roar of your generator. While generators have their uses, they also have the potential source of noise pollution.

In this blog post, we will cover 7 steps you can follow to reduce your generator noise by up to 80%. From mufflers and soundproof enclosures to sound-absorbing mats and noise-canceling devices, we have various options to choose from.


How to make a generator quiet?

6 professional approach to make your generator quitter are:

  1. Buy the right one for you your need
  2. Install a muffler or noise-reducing exhaust
  3. Build a soundproof enclosure
  4. Use a load-based speed control to turn down the RPM
  5. Install a sound-absorbing mat
  6. Install a noise-reducing baffle in the generator’s exhaust system

Buy the right one for you your need

If you are new to getting a generator, then we recommend buying the best quiet generator in the market. On the market, there are different types of generators. So, it is important to buy the type of generator that matches your needs.

If you need a generator for occasional use, you can choose a portable generator. The more powerful generator you will buy, the noisier it will be. So it’s necessary to understand your power limit & buy the right one according to your need.


Install a muffler or noise-reducing exhaust

The sound output of a generator can be considerably diminished by fitting it with a muffler or other noise-reducing exhaust. Mufflers reduce exhaust noise by scattering the vibrations and resonant frequencies produced by the exhaust gases as they go through the muffler’s internal structure. 

Glasspack mufflers chambered mufflers, and turbo mufflers are just some examples of the many varieties of mufflers on the market. 

Reduce the volume of your generator’s exhaust by slowing the exhaust gases as they leave the unit using a noise-reducing exhaust. A muffler or other noise-reducing components may be incorporated into these exhaust systems. 

A muffler or other noise-canceling exhaust system requires mechanical knowledge and possibly the help of a professional mechanic to install it. Nonetheless, the generator will be much more enjoyable to operate if the noise is reduced.


Build a soundproof enclosure

A generator can be made much quieter by placing it inside a soundproof cage. A soundproof room or enclosure works by preventing sound from reverberating outside the enclosed space. Soundproofing foam, drywall, and insulation are all viable options for constructing such an enclosure. 

The best way to ensure that no noise will leak out of a soundproof enclosure is to seal all the cracks and openings. Soundproofing materials are also recommended, as conventional construction materials may not be efficient at muting outside sounds. 

A professional constructor or at least someone with a firm grasp of the fundamentals of construction should be consulted when attempting to construct a soundproof enclosure. Nonetheless, the generator will be much more enjoyable to operate if the noise is reduced.


Use a load-based speed control to turn down the RPM

A generator’s revolutions per minute (RPM) are regulated by a load-based speed control system in response to the generator’s electrical load. The generator’s revolutions per minute (RPM) will be increased automatically to match the increasing demand while the generator is under load. If the generator’s load drops, the system will slow the generator’s rotational speed.

The most common load-based speed control system is using of a governor in a generator. A governor is a mechanism that detects the generator’s load and regulates the engine’s fuel supply to keep the RPM constant. 

When the generator’s load grows, the governor raises the fuel supply to the engine, causing the RPM to rise. When the load on the generator drops, the governor reduces the fuel flow to the engine to reduce the RPM. 

By continually modifying the generator’s RPM dependent on the load, the generator may run more efficiently and quietly.


Install a sound-absorbing mat

If you put a sound-absorbing mat under a generator, it will make less noise than usual. Sound-absorbing mats are made of materials that soak up sound waves instead of sending them back out.

 Putting a sound-absorbing mat under the generator is a simple and effective way to reduce noise & it doesn’t require any tools or special skills. But it is important to choose a mat that is thick enough and made from a material that is good at absorbing sound.


Install a noise-reducing baffle in the generator’s exhaust system

You can install a noise-reducing baffle in the exhaust system to reduce your generator noise. It disrupts the flow of exhaust gases that pass through the exhaust system. 

It works by rerouting the exhaust gases to make less noise when they come out of the exhaust pipe. The baffle is usually made of sound-absorbing material like foam or fiberglass. As the exhaust gases pass through the baffle, the sound-absorbing material soaks up some of the noise, making the exhaust noise less loud overall.


Install rubber feet

A generator can be made quieter by putting rubber feet on the bottom of it. This is because the rubber absorbs the vibrations from the generator & it acts as a barrier between the ground and the generator, which helps to reduce noise.

These rubber feet can also help to protect your unit from damage. If your generator is going to be used on uneven surfaces, the rubber feet can help to keep it level and stable. This can prolong the life of your generator and prevent costly repairs.
