How many decibels is a lawn mower? Noise Analysis

Want to know how loud a lawn mower is? We’ve got the answer. Our in-depth noise analysis provides the precise decibel count, ensuring you have the necessary information.

How many decibels does a lawnmower produce:

Gas-powered lawn mowers typically produce 85-100dB of noise, while electric mowers are quieter at 75-90dB. Noise above 85dB can cause hearing damage over time. For safety, earplugs should always be worn with any mower.

Have you ever thought about the noise your lawn mower makes? We’ve analyzed the decibel levels of both gas-powered and electric mowers. Continue to discover the potential risks to your hearing and learn how to mow safely.


How many decibels do lawnmowers make:

1. The noise level of different types of lawnmowers

We have made a handy table that indicates the noise levels of the various lawnmower types. Of course, a specific lawnmower’s noise level will depend on the brand, type, and maintenance. Several brands have made newer models more quit.

Lawnmower type
Noise Level
Lawnmower type
Noise Level
Robot mowers
55dB – 60dB
Reel mowers
60dB – 70dB
Simple, smaller Electric mower
75dB – 85dB
Self-riding gas Lawnmower
80dB – 90dB
Simple, smaller gas Lawnmower
85dB – 95dB
Self riding gas Lawnmower
85dB – 100dB
Large gas Ride Lawnmower
85db – 105dB

2. Are Lawnmowers loud?

A gas-powered engine can produce noise from 85 decibels, and an electric model from 75dB and up. This is much louder than a conversation between two people, around 50-65 dB. On the other hand, the difference between 65dB and 75dB is only 10 dB. But the dB scale is deciding.

A difference of 10 dB does not look like a lot, but it means that the relatively silent electric Lawnmower is double the sound level of two people speaking loudly. This is due to the logarithmic scale of dB. The sound intensity doubles after every 10 decibels.

This means a simple and relatively quiet gas Lawnmower (85dB) is twice as loud as a simple and relatively quiet electric lawnmower (75dB). Remember that a sound level above 85dB and up can result in hearing loss when you are exposed to it for an extended period.

With over two decades of experience in the field, the average decibel level of a lawn mower is typically around 90 decibels. It’s a common misconception that all lawnmowers produce the same amount of noise, but this can vary significantly based on several factors. It’s essential to be aware of this, especially if you’re using a lawn mower in a residential area.

3. Comparison between electric and gas-powered lawnmowers:

There are two types of engines used in a lawnmower. One is a gas-powered engine that works on fuel, and the other is an electric engine that works on electricity. These technologies differ a lot, but both are reasonable solutions for a lawnmower.

Electric lawnmowers are getting increasingly popular as they can be cheaper due to the lack of gas and less maintenance. They are also more environmentally friendly. There is also a big difference in the amount of sound they produce.

Electric lawnmowers are generally much quieter gas-powered cousins. Comparing the sound levels, an electric lawnmower always wins. It typically produces from 75dB and up, whereas gas-powered lawnmower products double the amount of sound with 85dB and up.

The sound of a gas-powered lawnmower also depends on the machine’s condition. How good is it maintained? A less maintained gas mower will be louder, whereas, in the case of an electric model, the influence is way less—also, the age of the mower matters.

The older it is, the more wear and tear the engine has seen, which results in a slightly louder lawnmower. For example, a gas-powered lawnmower can produce 85dB when it is a new model and in ideal condition, but after some years and less than the needed maintenance.

It can produce 90dB. 5dB does not sound like a lot, but it is much louder due to the logarithmic scale (10dB difference is twice as audible).

4. What is a safe noise level?

According to International Standards, a human ear should not be exposed to sound levels greater than 80 decibels. The green zone lies up to 80 decibels. Risks arise from 80-90 decibels, but only for long-term usage.

So, any level greater than 90 decibels can seriously cause damage (both permanent and critical) to human ears. So, a lawnmower should only be used with the proper precautions, like adequate hearing protection, to avoid hearing loss.

How can the noise of a lawnmower be reduced?

There are four primary sources of noise from a lawnmower:

  • Engine
  • Exhaust
  • Mechanical Vibrations
  • Blade

There are several ways how you can reduce the sound of your Lawnmower:

  1. Tighten the screws of the different engine components. Loose or partly loose screws can make components resonate with the engine vibrations. It also introduces much more wear and tear in the longer run.
  2. Keep a check on the engine. Make sure that the different engine components are well maintained. Regularly check the spark plug and the air filter. A poorly maintained engine has to work harder and produce more sound. Also, the wear and tear will be less in a well-maintained engine, making it last longer and less noisy in the long run.
  3. Check the muffler. The muffler significantly reduces the engine noise, but the noise produced can increase when damaged. For lawnmowers, you can exchange the stock muffler for a better version that makes your machine quieter.
  4. Protect your ears. Protect your ears by using adequate hearing protection like earmuffs or earplugs.
  5. Sharpen Lawnmower Blades:  Make sure that you regularly sharpen your lawnmower blades. With sharp blades, the mower needs less power to cut the grass, and the engine will produce less noise. A well-sharpened blade also cuts the grass much better.

Having worked with various outdoor tools for the past 20 years, I’ve noticed that a lawn mower is one of the louder tools, with noise levels comparable to a motorcycle. This might seem surprising to some, but it makes sense when you consider these machines' mechanics. It’s always important to consider the noise level when choosing and using outdoor tools.

Additional concerns:

1. Safety

It would be best to take safety precautions while using any machine as the sound the Lawnmower produces is relatively high. It can affect the human ear, so taking safety precautions before mowing your lawn is recommended.

As mentioned earlier, the sound of a lawn mower can be much louder than a daily conversation between two people.

These have safety precautions that are critical for your ears. You should wear either earplugs or earmuffs properly. Some models even have functions built to hear a person’s voice talking to you without taking them off.

2. If noise is a concern, check the use of an Electric Lawnmowers

The noise produced by an electric is significantly less than that of a gas-powered lawnmower. Its noise range starts from 75dB, much less than a gas machine.

You could even cut your grass without hearing protection, but this is not recommended. Hearing loss is not something that can be reversed.

Frequently asked questions:

Open Lawnmower produces a sound louder than usual; what should I do?

If your Lawnmower is producing a sound louder than usual, you should check its screws. If the screws are loose, tighten them properly. If the screws are tight, then probably the sound produced is from its engine.

The engine is involved in combustions and high rpm rotary components, which can be a critical factor in producing more than the average level noise, provided there is a problem.

Check them at once. The sound is sometimes also produced by its blades. If the blades have a loud sound, replace them at once. Use ear protection while using the Lawnmower. This will help you hear the person talking to you, which will protect your ear from damage.

2. Which Lawnmower is best?

This isn’t easy to answer. Each lawnmower type has advantages and disadvantages, and your best choice will significantly depend on your use case. If you like to have your lawn cut automatically, a robot mower can be the right choice.

Gas mowers can be a better option if you have a large area to cover or have a more challenging location. When the tank is empty, you refill it and continue. If your electric lawn mower battery is open, wait a while before continuing.

However, a gas-powered lawnmower is louder than an electric lawnmower and needs more maintenance. And with an electric lawnmower, it is just a push of a button, and you are ready to go, with no complicated starting procedures.

3. Why does my Lawnmower produce a high sound?

A gas lawn mower is a machine that contains a small engine. This small engine includes very small or maybe no mufflers. These cheap mufflers cannot control the level of noise as well as the more significant (more expensive) ones.

Gas lawnmowers have an exposed engine with many rotating and sliding parts and produce many sound waves. These small mufflers cannot absorb as many other sound waves as a more expensive one.

Besides the engine, the blade can also produce a high sound. The blades rotate at a high rpm, meaning the blades’ tips have a super high speed. This can result in a high sound.

In my experience, unusual rattling or knocking sounds could indicate a problem causing the mower to be louder than usual. Regular maintenance and inspections can help catch these issues early. A quiet mower is often a well-maintained mower.


Lawnmowers, especially gas-powered lawnmowers, are loud. The sound is unpleasant for the human ear, so equipment is necessary to protect your hearing. An electrical lawnmower produces less noise but can still be loud.

If your Lawnmower produces a sound louder than usual, don’t panic; check it immediately. A well-maintained lawnmower will be quieter and contribute less to pollution. Lawnmowers with noise levels around 80-95 decibels are the most common.

However, some of the best electric lawnmowers run at around 75 decibels, which is quieter. According to International Standards, they lie in the orange zone so that you can use them with no worries with proper safety equipment.

• The Need for Precaution in Gardening

For regular users involved in the field of gardening, more precaution is needed. If you want a quiet lawnmower, consider that electric lawn equipment is modest compared to their gas counterparts.

It’s also worth noting that using a quiet lawnmower is like standing next to a washing machine in terms of noise level. This is significantly quieter than a gas-powered lawnmower, which can be as loud as a motorcycle.

So, if you’re looking for options to reduce noise and maintain a clean-air lawn, an electric lawnmower from a reputable lawn care company might be a good choice. Remember, protecting the environment and your hearing should be a daily priority.
