Compressor Noise Control and Fan Noise Control- How to do it?

It’s no secret that air compressors are efficient energy producers. They provide power to critical industrial equipment and applications. Also, they produce heat from compressed air operations. This heat can reduce the need for extra energy and reduce expenses. But air compressors produce another type of energy. This energy is the unwanted sound energy.

Our perception of sound varies by a variety of environmental factors. Some of them include the distance from the source and the volume. When it comes to interior environments, these factors can include the size of the space. Also, they depend on the contents of the room and the capacity of various surfaces in the room to absorb or reflect sound.

When sound waves come into touch with a surface, a part of the waves absorbs into the surface. And, the remaining component deflects back to the source of the sound. The effectiveness with which a surface can absorb sound varies on the material. For example, consider the difference between the sound in a room with carpeting and the sound in a room with tile or hardwood floors!

What is it about air compressors that make them so loud?

A few variables contribute to the excessive noise produced by air compressors. Also, a majority of them relate to friction. Metal slapping against metal or sliding against metal may be quite noisy! Generally speaking, the greater the number of moving components in an air compressor, the louder it will be. This is also true in the case of the motor.

Because they generate combustion and have a large number of moving metal parts. Gas-powered compressors are almost certain to be noisier than electric compressors. The environment in which your compressor is operating might contribute to its noisiness.

Smooth concrete floors can amplify compressor noise in open areas. If the acoustics of your manufactured floor are like those of a huge gymnasium, this might be an issue.

What Are the Advantages of Compressor Noise Control?

Is it possible for you to tell me what the sound levels are for the many sounds that you hear on a daily basis? We measure sound levels in decibels (dB), which are letters that stand for decibels. Here are some frequent noises we hear on a daily basis, along with the normal decibel levels associated with them:

  • Leaves rustling – 30 dB
  • Normal conversation – 60 dB
  • Vacuum cleaner – 75 dB
  • ATV or motorcycle – 100 dB
  • Chainsaw – 115 dB
  • Crowd noise at a sporting event – 125 dB
  • Gunshot, fired at 100 feet – 140 dB

The sound levels produced by compressors can range from 40 to 92 decibels. Any noise level of more than 85 decibels is dangerous when exposed for an extended period of time.

The compressor noise control not only results in a more pleasant and delightful workplace, but it also makes workers healthier and safer!

How Can you Control Compressor or Fan Noise?

In order to determine and perform compressor or fan noise control, the size of a compressor room, the location of the compressors within the room, and the materials from which the room is made are all key aspects to consider. Additionally, the transmission of vibration via the compressed air pipe system has the potential to affect how sound travels across a whole building.

To assist keep noise levels down, it’s critical to equip a compressor and pipe system with the right vibration and sound insulators, or even encapsulate piping parts in sound-absorbing material, before starting up the compressor. Many stationary air compressors are also fitted with sound-dampening mechanisms. These mechanisms are often built-in.

Along with these items, there are four more efficient ways to reduce noise and make the workplace more pleasant while also making it safer.

3 Ways to Control Compressor or Fan Noise

Insulation against sound: This is accomplished by constructing an acoustic barrier between the sound source and the receiver. This means that, depending on the barrier and its specific properties, only a portion of the sound may be insulated. Unquestionably, a larger, heavier barrier will outperform a smaller one in terms of effectiveness.

Absorption of sound: It is possible to achieve a higher level of sound attenuation than that provided by insulation alone. You can surround the sound source with porous absorbents. Examples include open cell polyurethane foam or heavier textile applications.

Insulation against vibration: By restricting the passage of vibrations from one area of a structure to another, you may minimize the sound levels. When a major piece of machinery passes through the floor, this is one of the most prevalent areas of vibration transmission.

Steel springs, cork, plastic, and rubber are all materials that are effective in reducing this transfer of energy and any related sound. The material used for the machine depends on the machine’s size and the surrounding area. It also depends on the machine’s stability requirements.

It’s also important to remember that if the compressor is positioned in a location where it will come into touch with another item, the noise caused by this contact has the potential to grow significantly.

Vibration Damping for Compressor Noise Control

Vibration Dampening is a term that refers to the dampening of vibrations. Installing an external dampening surface made of an elastic material on the outside of a building is an efficient method of minimising the vibrations produced by the machine (and sound).

The more efficient the dampening barrier is in reducing vibrations, the more it is thought to be beneficial. This may turn out to be the most cost-effective options, but it will also produce the most restricted outcomes, on the other hand.
