How To Make Air Compressor Quieter - 11 Ways To Do It

Air compressors are essential tools in various industries, from manufacturing to construction as they provide high-pressure air to power pneumatic tools and equipment, making work easier and faster. However, one of the significant drawbacks of air compressors is their noise level as air compressors can produce a lot of noise which can be disruptive and even harmful to the operators' health. Fortunately, there are ways to make compressors quieter and in this article, I will list the different methods that you can use to reduce the noise level of your air compressor. So without any further ado let's take a look at it.

Understanding the Noise Level of Air Compressors:

Before we dive into the different methods of making it quieter, it's essential to understand the source of the noise. Air compressors produce two types of noise: mechanical noise and air noise. Mechanical noise is produced by the moving parts of the compressor such as the pistons, valves, and motor. Air noise on the other hand is produced by the air moving through the compressor's components and the discharge of compressed air.

The noise level of an air compressor is measured in decibels (dB) and a typical air compressor can produce noise levels between 40 and 100 dB. Prolonged exposure to noise levels above 85 dB can cause damage to your ears, so it's crucial to take measures to reduce the noise level of your air compressor.

Methods to Make Air Compressors Quieter:

Choose a Quieter Air Compressor:

The first and most obvious way to make your air compressor quieter is to choose a quieter model as some air compressors are designed to produce less noise than others.

Look for air compressors that are designed with noise reduction in mind as these models often have sound-dampening features. A quieter air compressor will have a lower noise level, which means less noise pollution in your workplace, and a nice example of that is this California (8010) Air Compressor on amazon as it has a noise level of 60 dB which is quite impressive.

Install Sound-Dampening Enclosures:

If you already have an air compressor that produces a lot of noise, you can install a sound-dampening enclosure around it to reduce the noise level.

Sound-dampening enclosures are made of materials that absorb sound waves such as foam, rubber, or fiberglass and this enclosure should be designed perfectly to fit the compressor but leave room for ventilation.

This method can significantly reduce the noise level of your air compressor.

Use Anti-Vibration Pads:

Air compressors can produce a lot of vibration which can contribute to the noise level and you can reduce the vibration by using anti-vibration pads under the air compressor's feet.

These pads absorb the vibration, reducing the noise level and preventing damage to the compressor's components. Anti-vibration pads are inexpensive and easy to install.

Install A Silencer:

Another way to reduce the noise level of your unit is to install a silencer. A silencer is a device that reduces the noise level of the compressed air as it enters and exits the compressor.

Silencers are usually made of materials that absorb sound waves to dampen the sound thus reducing the noise level. Installing a silencer can significantly reduce the noise level of your air compressor.

Use Soundproof Curtains:

If you're looking for a portable solution to reduce the sound level of your compressor then you can use soundproof curtains.

Soundproof curtains are made of heavy-duty materials that absorb sound waves such as vinyl or fiberglass and you can hang the curtains around the air compressor to create a soundproof barrier.

This method is easy to install and remove, making it ideal for temporary or mobile setups.

Maintain Your Air Compressor:

Proper maintenance of your air compressor can also contribute to reducing the noise level as regular maintenance can prevent the compressor's components from wearing out or becoming damaged, which can increase the noise level.

You should regularly check and replace worn components such as belts, filters, and bearings. Keeping the compressor clean and lubricated can also reduce the noise level and prolong its lifespan.

Move The Compressor Away From Workspaces:

One of the easiest ways to reduce the noise level is to move it away from the workplace. The farther away the compressor is from the work area the less noisy it will be.

This is especially important in small workshops where the compressor is located close to the workbench or other work areas. Moving the compressor to a separate room or a soundproof enclosure can significantly reduce its noise level.

Wrap Sound Blankets Around The Air Compressor:

Another effective way is to wrap sound blankets directly around the compressor itself as sound blankets are made of sound-absorbing materials and can be easily wrapped around the compressor to reduce its noise level.

The blankets can be purchased online or at hardware stores and come in various sizes.

Place It On A Rubber Mat:

Rubber mats absorb vibrations and thus reduce the noise level by preventing the compressor from vibrating against the floor.

The mat also provides a stable surface for the compressor, which can help to reduce its noise level even further and the rubber mats can also be purchased online or at hardware stores and come in different sizes as well.

Change Air Filters If They Are Dirty Or Worn Out:

The air filters on an air compressor are designed to prevent dust and debris from entering the compressor and causing damage to the internal components.

Over time, these filters can become clogged with dirt or debris reducing the airflow and increasing the noise level of the compressor. The frequency of filter changes will depend on how frequently the compressor is used and the environment in which it is used. It is recommended to change the filters when they appear visibly dirty or worn.

Tighten Up Any Loose Bolts Or Screws:

An air compressor that has loose bolts or screws can vibrate excessively causing it to make more noise than necessary.

So it is important to check for loose bolts as well as screws regularly and tighten them up if necessary as this will help to reduce the vibrations and minimize the noise level of the compressor.

Frequently Asked Questions (FAQ):

What Makes An Air Compressor Noisy?

The main factors that contribute to the noise generated by an air compressor are the vibration and movement of its internal components, the flow of compressed air, and the sound of the motor and fan.

How Many dB Is A Quiet Air Compressor?

The noise level of an air compressor is measured in decibels (dB) and can range from 40 dB for ultra-quiet models to over 90 dB or 100 dB for industrial-grade compressors.

A quiet air compressor is typically one that produces less than 60 or 70 dB of noise.

Is Higher dB Quieter?

No, higher dB means louder, not quieter. The decibel (dB) scale measures sound intensity or loudness and a higher dB level indicates a louder noise.

Therefore, a lower dB level corresponds to a quieter sound.


Air compressors are essential tools in various industries but their noise level can cause a lot of problems for yourself and other people.

But above I have mentioned several ways to make your air compressors quieter and from these options, you can either choose a quieter air compressor, install sound-dampening enclosures, use anti-vibration pads, install a silencer, use soundproof curtains, etc.

By taking these measures, you can significantly reduce the noise level of your air tool and create a safer as well as comfortable workplace. If you find this article to be helpful then share it with folks and have a nice day.
