Screw air compressors are known for being efficient but notoriously noisy. In industrial environments like power plants, the excessive noise can disrupt workflows and pose health risks to employees. So, how do factories manage and reduce this noise effectively? Let’s take a closer look at practical soundproofing solutions used in compressor rooms—especially within power generation facilities.
Why Is Noise Control Important in Compressor Rooms?
Noise pollution from screw air compressors not only creates an uncomfortable working environment but also poses long-term hearing hazards for employees and contributes to environmental disturbance. Controlling this noise is essential for:
- Ensuring workplace safety and comfort
- Complying with noise regulation standards
- Extending the lifespan of surrounding machinery by reducing vibration impact

The Power Plant Approach: Installing Acoustic Walls
In power plants and large industrial factories, acoustic walls are the most commonly used solution for compressor room soundproofing. These walls are engineered to reduce noise by reflecting and dispersing sound waves, converting them from direct mirror reflection to diffuse reflection.
What Are Acoustic Walls Made Of?
Acoustic walls, similar to those used in recording studios or sound booths, are typically composed of:
- Absorptive surface (sound-absorbing material) on one side
- Reflective and insulating material on the opposite side
This dual structure helps in both reducing sound transfer and tuning the quality of the sound environment.
Materials commonly used include:
- Galvanized steel or aluminum panels
- Perforated or corrugated metal designs
- Laminated safety glass or polycarbonate sheets
- Spring clamps and steel pillars for secure installation

Recommended Thickness for Compressor Room Acoustic Walls
Generally, the thicker the wall, the better the noise reduction. However, this comes with increased cost. In industrial settings, a standard wall thickness of 80 mm is often sufficient to balance performance and budget.
Where Are Acoustic Walls Installed?
To maximize efficiency and minimize construction costs, acoustic walls are usually installed:
- As close as possible to the noise source (the compressor)
- Along existing concrete walls of the factory
- Using vertical support pillars when wall height exceeds standard structure
These installations form a complete soundproof enclosure around the compressor system.

Conclusion: Reducing Screw Air Compressor Noise in Factories
Controlling the noise generated by screw air compressors is crucial for modern industrial operations. By installing properly engineered acoustic walls with suitable materials and thickness, factories—especially power plants—can significantly reduce compressor noise, improve workplace comfort, and meet safety regulations.
