How to Quiet Air Compressor Noise Within Few Steps!

Air compressors are devices that help compress air and run different types of power tools. Whether you are using an electric air compressor or just one that needs oil to starts, they are famous for making loud noise levels.

Of course, air compressors come in for various projects around the house, but the noise is almost unbearable. Almost all air compressors can able to produce sounds between the ranges of 70 to 90 dB (decibels).

You know, the human ear can only handle around 80 decibels of sound range. Anything above that can cause damage to your ear, especially if one is exposed to the sound for a long time.

No wonder why people overthink making an air compressor quieter for their workplace!

Luckily, here are some easy steps to try on how to reduce air compressor noise?

How to Make an Air Compressor Quiet (Infographic)

Quiet Air Compressor

Now you have a full summary idea and need to know how to quiet an air compressor? Let’s drive into a full-depth review. Where we talked about more than 5 ways to do this task.

Use a Muffler/Silencer Box

This is an inexpensive way to deal with this air compressor noise issue. A muffler is often used in motor cars or bikes. It can install on the air intake to reduce the air compressor noise levels by 2 decibels. Some mufflers can have fewer noise levels up to 4 decibels and it’s a bit more expensive.

But considering your heart is at stake here, it’s a small investment that is worth making. You can connect a muffler to one end of an air hose. Then you can connect the other end to the air intake component. You can get a muffler or air compressor silencer box online or from your nearby shop. It will give heavy-duty to making your air compressor quieter than before.

Use Sound Blanket for Quiet an Air Compressor

Apart from the exhaust and intake, the air compressor’s piston cylinder is one of its common causes of much noise. Air compressor sound blankets can prevent that noise from being echoed or boosted up due to reflection from the walls in your room. You can put sound blankets on the wall, and it will prevent the amplification of sound.

Sound blankets can absorb medium to high-frequency sounds level. So they are pretty handy for quieting air compressors if you place them properly.

Shift the Air-Intake Outside

Most of the noise comes from the air compressor intake component. To reduce the noise level, you should use an extended rubber hose. It let the machines suck the air from the free area outside and in turn, consumes the noise. You can also use a pipe, it will work like air intake.

Likewise, as you can keep the pipe or hose out, you won’t be hearing the sound as louder as before when working indoors.

Make a Noise Reduction Box for Quiet Air Compressors

This is perhaps, the most effective way to deal with the noisy stuff when you’re using an air compressor in house. This means, building a

soundproof box for preventing unusual noise and reducing the air compressor’s throat. You can make a DIY soundproof enclosure for your power generator out of cardboard or foaming substance. And you can use fire-resistant materials like gypsum or hard concrete for creating the noise reduction box.

Air Compressor Noise Reduction Box

The unit of the compressor should be inside the enclosure, and there need to be openings for the exhaust and wires. If the power outlets and hoses are left trapped inside a confined space like the enclosure, there might be accidents.

These are the important materials you’ll need to make your air compressor quieter box:

  • A saw (circular ones are better)
  • Screws
  • A Driller
  • Foam
  • Adhesive spray

Modifying such a soundproof enclosure box for your air compressor is an easy way to reduce noise drastically. If your air tool doesn’t produce earth-shattering noise, to begin with, this soundproof box might make the entire sound fall to a minimum.

Use Rubber Grommet

Rubber has sound level deadening capabilities, and it’s a probable solution. You can find rubber grommets on Amazon from around $2 to $10 or more prices. There are different sizes of rubber grommets available in the market so you can get one according to your machines.

If the motor is secured using this rubber, you can reduce the noise significantly. The vibration in the engines causes a lot of noise when air compressors start. As the rubber absorbs the vibrations, it reduces the noise levels to act as an air compressor’s sound deadening.

Maintain the Air Filter

Air filters clean the air when the compressor sucks in. So if they don’t work properly and get dusty, the compression process will get noisy. In that case, before the filters get clogged, it’s good to clean them up and save your compressor.

Therefore, it’s recommended to clean up them at least once every 12 months though this does depend on where you live and its uses. The dusty environment calls for more cleaning.

Use Lubricant for the Parts

Oil-less air compressors tend to make more noise than others. If you are wondering to quiet an oilless air compressor, lubrication is your answer. The friction between the different types of parts is the reason behind all the annoying noises. That’s why it is essential to oil and lubricate the components to prevent friction and rust.

Air Compressor Lubrication

Accordingly, lubricating the moving parts with grease can reduce corrosion and make your air compressors more durable. But it is to be noted that too much grease can make the bearings of the machine difficult to move.

Hence, this might damage the compressor engine. So, you should use just the right amount of lubricant.

Buy a Top-Quality Air Compressor

This is an obvious solution. If you get an air compressor of better quality materials after checking the decibel (dB) count, there’s less chance of having a headache due to crazy noises from your compressor. A cheap budget new air compressor will only cost more in the long run with all the parts needing touch-ups and replacements again and again.

Get Professional Help

It’s always good to let experts help out when you’re confused about what the problem is? And how do you make your air compressor quieter?

Only a professional or experienced person can easily tell what the clicking sound, humming motors, and squeals at the startup of the machine really matter.

Once a year, it is good to have your air compressor serviced. Regular checkups of your air compressor can ensure top-notch performance and durability.


So, here in our reviews bottom line is if you really want to know how to quiet an air compressor’s noise and save your health from unwanted damages? Our above guide will surely help to make your work less boring and protect your ears from any possible harm.
