Nothing gives your home a nice look like a well-maintained lawn. But every time you think of mowing your yard, you get frustrated. Lawnmowers can be noisy. Everyone in your neighborhood will know that you are mowing your home. If you do it regularly, they might also not like you.
The noise from the blades and the engine can be too much. But that should not be the case. There are simple things you can do to reduce the noise produced by your mower. In this article, we will discuss tested techniques that will solve this problem for you.
Let’s dive deeper and learn how to make a lawnmower quieter.
What’s the Acceptable Noise Level for a Lawn Mower?
Lawnmowers vary in the noise they make. Unfortunately, most of the mowers are quite loud. You can, however, choose to buy quieter lawn mowers or soundproof the one you have.
When mowing, you should also wear protective gear for your ears.
Most mowers produce a noise level of around 90 dB (Decibel). This is high than the recommended noise level for your ears. No one should be subject to this noise level for over eight hours.
Techniques to Reduce Noise Levels for a Lawn Mower
Below are the top ways to deal with the noise produced by your lawnmower.
1. Work on Your muffler
Most lawn mowers have a muffler installed on the engine. It specifically fixed at the exhaust port. The muffler forces the engine sound to pass through a noise-canceling chamber. It also provides pressure for the engine so that it can work at its maximum horsepower.
With time, the muffler cracks. The gasket seal between the exhaust pipe and muffler can also deteriorate. As a result, the engine noise is not canceled and they remain louder than desired.
Therefore, if your lawnmower is producing a lot of noise, inspect and fix the muffler. Carry out the following steps to work on your lawnmower muffler.
Step 1: Allow the Engine to Cool down. The exhaust pipe gets extremely hot when the engine is running. You cannot work on the muffler at this state.
Step 2: Locate where the muffler has been installed in the exhaust pipe.
Step 3: Unscrew the two bolts holding exhaust pipe to the port on the engine. Pull the pipe off to reach out to the muffler.
Step 4: Inspect the muffler. Check whether there are any cracks on it. Check also whether it has rusted also. This is mainly caused by continuous condensation. If the muffler has rusted or cracked replace It with a new one.
Step 5: Peel of the old gasket from the exhaust port. Scratch and remove any debris. Fix a new gasket over the exhaust port. Return the exhaust pipe and tighten it to the exhaust port.
If you are unable to follow the above procedure on your own, seek help from a professional. Don’t attempt to change anything if you are not confident enough. But if you are confident, the above stages are easy to follow.
After this process, your lawnmower should be silent. If the mower still makes more noise, consider other techniques of making the lawnmower quieter. Keep on reading to discover other amazing techniques to make a lawnmower quieter.

3. Install Engine Silencers on Your Lawn Mower
Silencers work the same with combustion engine mufflers in automotive engines. The silencers reduce the noise produced during combustion by the water lawnmower engine.
Engine silencers are mainly into three categories. Every category determines the level of noise reduction applied to your lawn mower.
Reactive silencers: They should be connected by a tube to the engine exhaust. The muffler has three internal chambers. Exhaust noise bounces between the chambers and reduces the noise produced by the lawn mower. Reactive silencer should be used to reduce low to mid-level noise.
Absorptive Silencer: This is a silencer with E glass or fiberglass insulation in its internal construction. When connected to the lawnmower exhaust, it dampens the vibration and sound produced by the engine. Absorptive silencers are perfect for reducing the high-frequency noise level lawnmowers.
Combination silencer: As the name suggests, it combines the technology of absorptive and reactive silencers. It’s fixed like all the other silencers. Combination silencer reduces all levels of sound frequency from the lawnmower.
Before, fixing any silencer on your lawnmower, consult your mechanic. We recommend the following silencers. They are all available on Amazon.
- 18 Inches long
- Coupler for Gen-Turi Generator Exhaust System

4. Always Wear Hear Protective Gears When Mowing
You can manage to quiet your lawnmower. However, it will still produce a substantial amount of noise that will bother the person using the mower.
The structural noise from the lawnmower is not good for your hear drums. With time, they can damage your hearing. Currently, many people are half-deaf due to loud machinery. Having conversations with them can be a difficult experience.
We are sure you don’t want to be that person who is half-deaf.
Therefore, to prevent blowing your eardrums buy ear muffs or plugs. Hear muffs cover the entire ears. They provide greater noise reduction as compared to earplugs. The earplugs also work well in reducing the mower noise.
Buy quality brands on Amazon. You can check either of the following brands and always wear them every time you are mowing. Feel free to use them every time you want to stop hearing any kind of noise.
- Noise Reduction Safety Ear Muffs,
- Shooters Hearing Protection Ear Muffs,
- Adjustable Shooting Ear Muffs,
- NRR 28dB Ear Defenders for Shooting Hunting Season
- Shooters Hearing Protection Safety Ear Muffs

5. Buy a Quieter Mower
Just like most types of machinery, some lawn mowers are noisier than others. And we are not experts in all machinery, but we understand much about lawnmowers. We have been mowing our backyard for as long as we can remember.
Electric mowers are quieter than gas-powered mowers. Mowers with smaller engines also produce less noise than the ones will large engines.
So if soundproofing your loud mower is expensive, consider buying a quieter one. For example, changing mufflers time overtime is costly in the long run. When you add up the cost of maintaining a noisy mower is too high than an electric mower.
Therefore, choose an electric over the gas-fueled mower.
