Generators have become a staple in many households and businesses as a backup power source. However, the loud noise that they emit can be a major inconvenience and a source of disturbance to the environment.

If you’re looking to keep the peace, it’s important to understand how to reduce the noise that your generator produces.

Skip the hassle and check our list of quietest generators on the market!

Understanding the Noise

A generator operates by converting mechanical energy into electrical energy. The process of converting this energy results in the production of sound, which can be loud and disruptive. The noise from a generator is measured in decibels (dB) and can range from 60 to 100 decibels. A decibel level of 60 is considered the threshold of normal conversation, while a decibel level of 100 is equivalent to the sound of a jet engine.

The decibel level of a generator depends on several factors, including its size, the type of fuel it uses, and the type of engine it employs. The environment in which the generator is placed can also contribute to the noise level. For example, a generator placed near a hard surface, such as a wall or fence, will produce more noise than one placed in an open field.

Best Practices for Reducing Generator Noise

The good news is that there are several measures that you can take to reduce the noise produced by your generator.

Proper Placement and Installation

The first step in reducing generator noise is to properly place and install it. It’s important to place the generator on a level surface that is isolated from other structures. This will help to reduce the amount of sound that is reflected back toward your home or business. Additionally, you should keep the generator as far away from windows and doors as possible.

Use of Soundproofing Materials

Another way to reduce generator noise is to use soundproofing materials. There are several materials that can be used to absorb sound and reduce the decibel level of your generator. These materials include soundproof foam, mass loaded vinyl, and acoustic panels.

Maintenance and Upkeep of the Generator

Regular maintenance and upkeep of your generator can also help to reduce noise levels. This includes checking the air filter, changing the oil, and checking the spark plug. If your generator has a muffler, it’s important to keep it in good condition to ensure that it is functioning properly.

Use of Acoustic Enclosures or Mufflers

If you want to significantly reduce the noise produced by your generator, consider using an acoustic enclosure or muffler. These enclosures are designed to reduce the decibel level of your generator and provide a quiet, peaceful environment. There are several types of enclosures available, including soundproof boxes, containers, and tents.

DIY Soundproofing Solutions

If you’re handy and prefer a more hands-on approach, there are several DIY soundproofing solutions that you can try.

Materials you can use to reduce generator noise

The materials you will need to reduce generator noise include:

  • Soundproof foam
  • Mass loaded vinyl
  • Acoustic panels
  • Weather stripping

Step by Step Instructions for Soundproofing a Generator

  1. Measure the generator to determine the size of the soundproofing materials you will need.
  2. Cut the soundproof foam to size and attach it to the surface of the generator using adhesive.
  3. Apply a layer of mass loaded vinyl over the foam.
  4. Cut the acoustic panels to size and attach them to the inside of the generator’s enclosure.
  5. Seal any gaps around the generator with weather stripping to prevent sound from escaping.

Tips and Tricks for Effective Soundproofing

  • Use multiple layers of soundproofing materials for maximum effectiveness.
  • Pay attention to the joints and seams of the generator’s enclosure, as these areas can allow sound to escape.
  • Consider adding additional insulation to the generator’s enclosure to further reduce noise.
  • Experiment with different materials and techniques to find the combination that works best for your generator.

Commercial Solutions

If you’re not comfortable with DIY solutions or want a more comprehensive solution, there are several commercial soundproofing solutions available.

Acoustic Enclosures and Mufflers

Acoustic enclosures and mufflers are specifically designed to reduce generator noise. These products are made from soundproof materials and are designed to fit around your generator to create a quiet environment. There are several types of enclosures and mufflers available, including:

  • Soundproof boxes
  • Containers
  • Tents

Soundproof Boxes and Containers

Soundproof boxes and containers are designed to encase your generator and reduce the noise it produces. These products are made from soundproof materials and are designed to fit snugly around your generator.

Pros and Cons of Commercial Soundproofing Solutions

Commercial soundproofing solutions are a great option if you want a quick and easy way to reduce generator noise. However, there are also some disadvantages to consider. The cost of commercial solutions can be high, and the products may not fit your generator perfectly. Additionally, some commercial solutions can be difficult to install and may not provide the level of soundproofing that you are looking for.


Making your generator quiet as a cricket is an important step in reducing noise pollution and ensuring that you have a peaceful environment. By understanding the causes of generator noise and the measures that you can take to reduce it, you can enjoy a quiet and peaceful environment. Whether you choose a DIY solution or a commercial product, there are several options available to help you reduce generator noise.
