How to Quiet an Air Compressor: 7 Noise Reduction DIY Hacks?

Want to learn how to quiet an air compressor?

Well, stick to the end of this article as we share different air compressor noise reduction hacks.

Quiet air compressors play an essential role in our homes, job sites, and garages.

Unfortunately, all air compressors have one thing in common- they are quite loud.

The most convenient method would be to invest in a new quiet air compressor.

Unfortunately, these quiet air compressors are quite expensive, and not everyone can afford them.

If you’re on a budget, it’d be wise to make your existing compressor quiet using these simple do it yourself hacks.

Let’s get started.

Why Air Compressors Are Loud

Before looking for ways to quiet an air compressor, you should understand why it makes noise.

An air compressor can make noise because of so many reasons, some of them being:

Air Compressor’s Materials

The materials used in the making of the air compressor also determines how loud it’s going to be. (*)

If your air compressor is made of thin, low-quality materials, then it will definitely be loud.

However, if it is made of high-quality material, which is also hard, the noise will be much less.

The Size of the Air Compressor

The size is also a big determiner of how loud it’s going to be.

This is because the size determines how much air the machine will suck when in operation and engine power, which is a significant contributor to noise.

Air Exhaust & Air Intake

The exhaust is also among the biggest contributor to noise.

So, you should check out this when looking for areas that are emitting noise.

The air intake in an air compressor also determines how loud it’s going to be.

When the air is being sucked into the air compressor, the machine will produce noise.

Now that you know the parts responsible for noises in your air compressor, the next step is understanding how to minimize the noise.

The Floor

The floor is a significant contributor to noise from the air compressor, particularly vibrational noise.

This noise is called impact noise and is produced when the compressor interacts with the floor it is placed on while in operation.

Impact noise will depend on the materials the floor is made of; the harder the material, the louder the noise.

Ways on How to Quiet an Air Compressor

Now that you know the different factors contributing to air compressor noise let’s fix the noise problem.

1.  Shift the Valve Outdoor

As mentioned above, a lot of noise is produced when the air processor sucks in air through the valve.

The noise will be exceptionally high if the air compressor is inside your home.

The best solution for this is shifting the air valve outside.

However, this doesn’t mean carrying the air compressor outside but extending the valve outside.

Air is consumed through the air intake valve, so shifting it outside will significantly reduce the noise in your home.

The best way to do it is by using a rubber hose.

Connect the rubber hose to the valve, then hold it in place using a rubber grommet.

Once connected, extend the hose outside.

You can do this by passing the hose through the wall to the outside.

Keep in mind that passing it through the door or the window will cause the noise to spread back to the house.

2. Tighten the Air Compressor

Loose parts in your air compressor can also contribute to the noise you are hearing.

If this is the case, you should try tightening the screws of every loose part in the air compressor.

Check loose screws and bolts because they are notorious for becoming loose over a long period after continual use.

Ensure you thoroughly check the air compressor for the loose parts, then fix them.

However, if there are no loose parts, then the problem could be something else.

3. Install an Air Muffler

An air muffler is a good way of silencing your air compressor.

If you choose to attach the hose to the air valve, connect the end to a muffler.

Then connect the other end to the muffler.

Once you have done this, the noise will significantly reduce to about 4db.

This method is similar to extending the valve outside only that, in this case, you use a muffler inside the house.

4. Clean the Filters

Another cause of the noise from your air compressor is the air filters.

When in operation, the filter is bound to collect dust, debris mainly because its work is to clean the air being sucked in.

If you stay too long without cleaning the filters, the dirt will accumulate and cause the compressor to run harder because of less air being sucked in.

As the machine runs harder, the louder it’s going to be.

The best solution to this is regularly cleaning the air filters.

5. Soundproof Box

Another option you can consider is putting the air compressor in a soundproof box.

A soundproof box is built with soundproofing materials that make it a good means of deadening noise from the air compressor.

You have the option of buying the soundproof box, but it would be much cheaper if you constructed one yourself.

If you plan on creating one at home, you will need saw plywood, screws, and drills.

Measure the air compressor and use those measurements to build the box.

Ensure you add a few inches to prevent creating a tight space that may lead to overheating.

Also, drill a few holes in the box to allow free flow of air.

You can add acoustic foam to the inner part of the box to effectively deaden the noise.

6. Use Ear Plugs

If you lack basic DIY soundproofing skills and want a simple way to deaden the noise problem, why not try earplugs.

Earplugs are beneficial, especially as a quick solution to the noise you are experiencing.

Remember that continued exposure to loud noises will eventually affect your hearing.

The best thing to do is to wear earplugs.

7. Cover the Compressor

You could also try covering the air compressor with blankets to deaden the noise.

You could use the regular blankets, but they won’t work well like sound blankets.

Sound blankets are made of soundproofing properties that absorb noise and consequently reduce it.

The blankets fibers help in the absorption of the noise.

When covering the air compressor, ensure you locate the nosiest part, then cover it.

If you built a soundproof box, you could try covering it with a blanket to reduce the noise.

You could also line the inside part of the soundproof box with the blankest instead of acoustic foam.

On how to Quiet an Air Compressor

While air compressors play an essential role in our homes, it’s unfortunate that they can be quite loud.

Above are some of the best methods on how to quiet an air compressor.

These are simple DIY hacks that are much cheaper compared to investing in a new quiet air compressor.
