Use a Muffler/Silencer Box:

This is an inexpensive way to deal with the problem. A muffler is often used in motor cars or bikes. It can be installed on the intake to reduce the air compressor noise by 2 decibels. Some mufflers can cut it up to 4 decibels and is a bit more expensive.

But considering your hearing 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 intake. You can get a muffler or air compressor silencer box online or from your local air tools shop. It will gives heavy duty to making your compressor quieter then before.

Use Sound Blankets:

Apart from the exhaust and intake, the compressor’s piston cylinder is one of its prime causes of loud noise. 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 amplification of sound.

Sound blankets can absorb medium to high-frequency sounds. So they are pretty handy to quieting air compressor.

Shift the Intake Outside:

Most of the noise comes from the intake. To reduce its noise, you should use an extended rubber hose. It lets the machine suck the air from free areas outside and in turn, reduces the noise. You can also use a pipe.

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

Make a Noise Reduction Box:

This is, perhaps, the most effective way to deal with the problem of noisy machines. Means, making soundproof box for preventing unusual noise and quiet air compressors throat. You can make a DIY sound enclosure for your power generator out of cardboard or foaming substance. And you can use a fire-resistant material like gypsum or hard concrete for making the 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 main items you’ll need for making your compressor quieter box:

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

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

Use Rubber Grommets:

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

Rubber Grommets

If the motor is secured using rubber grommet, you can reduce the noise significantly. The vibrations in the engine cause a lot of noise when an air compressor is run. As the rubber absorbs the vibrations, it reduces the noise too acting as an air compressor noise suppressor.

Maintain the Air Filters:

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

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 Lubrication for the Parts:

Oil-less air compressors tend to make more noise than others. If you are wondering how to quiet an oil-less air compressor, lubrication is your answer. The friction between the different parts is the main reason behind all the annoying noise. 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 tools 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 engine. So, you should use just the right amount of lubricant.

Buy a Good Quality Compressor:

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