How Loud is a Generac Generator? (Ultimate Guide) In 2023

How Loud is a Generac Generator? Generac generators have gained popularity for providing backup power during outages.

However, one common concern among potential buyers is the noise level these generators produce.

In this article, we will delve into the topic of how loud a Generac generator is, exploring factors that influence noise levels, measuring noise in decibels, and offering practical tips to reduce generator noise.

How Loud is a Generac Generator

How Loud is a Generac Generator?

The loudness of a Generac generator varies depending on the specific model and size, but they are generally designed to operate quietly, making them suitable for both residential and commercial use.

Typically, noise levels for Generac generators range from around 60 to 70 decibels at a normal load, which is comparable to a conversation or background music.

However, it’s essential to check the specifications of the particular model you’re interested in for precise noise level information.

Understanding The Decibels (dB)

Before we dive into the specifics of Generac generator noise levels, let’s first understand decibels (dB). Decibels are a unit of measurement used to quantify sound intensity or loudness.

The higher the dB level, the louder the sound. For reference, here are some common sounds and their approximate dB levels:

  • Whisper: 20-30 dB
  • Normal conversation: 60-70 dB
  • Lawnmower: 85-90 dB
  • Rock concert: 110-120 dB
  • Jet engine: 130-140 dB

Factors Influencing Generac Generator Noise

Generac generators come in various models, and the noise level can vary depending on several factors:

1. Generator Size and Power Output

Generally, larger generators with higher power output tend to produce more noise than smaller ones. This is because larger engines are required to generate more electricity, which can result in increased noise.

2. Engine Type

The type of engine in a Generac generator can significantly affect noise levels. Generac offers both air-cooled and liquid-cooled generators. Air-cooled models tend to be noisier than their liquid-cooled counterparts.

3. RPM (Revolutions Per Minute)

The engine’s RPM can impact noise levels. Generators running at higher RPMs are often louder than those running at lower RPMs. However, higher RPM generators may offer more power.

4. Soundproofing and Enclosures

Generac generators may come with soundproofing measures and enclosures designed to reduce noise. Models with better soundproofing tend to be quieter.

Measuring Generac Generator Noise

Generac provides noise level information for each of its generator models. This information is usually measured in dB at a specific distance,

such as 23 feet. When comparing generator noise levels, always check the manufacturer’s specifications.

Tips for Reducing Generac Generator Noise

If you’re concerned about the noise your Generac generator produces, here are some practical tips to help reduce it:

1. Proper Placement

Position the generator as far away from your home as possible while maintaining safety measures. The farther it is, the less you’ll hear it inside your house.

2. Sound Barriers

Consider using sound barriers like acoustic fencing or walls to block and absorb generator noise.

3. Generator Enclosure

Invest in a generator enclosure or soundproof cabinet designed to house your Generac generator. These can significantly reduce noise.

4. Regular Maintenance

Maintain your generator as per the manufacturer’s recommendations. A well-maintained generator is likely to operate more quietly.

People also ask

Do Generac generators make a loud noise?

Generac generators can produce varying levels of noise, but they are generally considered to be on the louder side when compared to some other generator brands.

The noise level largely depends on factors such as generator size, engine type, and RPM.

To get specific information about the noise level of a particular Generac generator model, it’s best to refer to the manufacturer’s specifications.

Is Generac a quiet generator?

Generac generators are not typically considered quiet generators. They can produce significant noise, especially larger models and those with air-cooled engines.

However, noise levels can vary among different Generac generator models, so it’s essential to check the specifications for the specific generator you’re interested in to determine its noise level.

How many decibels is a 22kw Generac generator?

The noise level of a 22kW Generac generator can vary depending on factors such as the specific model, the type of engine, and whether it has soundproofing.

To determine the exact decibel rating for a particular 22kW Generac generator, you should refer to the manufacturer’s specifications for that specific model.

How noisy are natural gas generators?

Natural gas generators are generally quieter compared to diesel or gasoline generators.

They produce less noise because natural gas burns cleaner and more efficiently.

However, the noise level can still vary depending on the generator’s size, design, and soundproofing.

To know the exact noise level of a particular natural gas generator, you should refer to the manufacturer’s specifications.


In conclusion, the loudness of a Generac generator can vary depending on several factors, including its model, size, and load capacity.

However, Generac generators are generally designed to operate with minimal noise, making them a suitable choice for both residential and commercial applications.

It’s important to consult the specific product specifications and user reviews to get a precise understanding of the noise level for a particular Generac generator model.

Overall, Generac strives to provide reliable power solutions without causing excessive noise disturbances, enhancing its appeal to a wide range of users seeking a balance between power generation and noise control.
