Cooling Tower Noise Control

Engineered noise control solutions for cooling towers — designed, manufactured, and installed by ARK Noise Control (India)

Why Cooling Tower Noise Needs Control

Cooling towers generate 80-100 dB(A) from fan operation, water splash impact, and air-water interaction. The noise emanates from large open areas (air inlets, fan stacks), making it difficult to contain with conventional enclosure methods. Cooling tower noise is a frequent source of community complaints.

How ARK Solves Cooling Tower Noise

ARK provides multi-faceted cooling tower noise control solutions combining fan stack silencers/attenuators, air inlet acoustic louvers or barriers, splash noise barriers, and low-noise fan blade options. The solution is custom-designed based on the specific noise sources, directional characteristics, and target noise levels at the plant boundary and nearest sensitive receptors.

Key Benefits

  • Noise reduction of 10 to 25 dB(A) at the source
  • Fan stack attenuators for discharge noise control
  • Air inlet acoustic louvers to reduce intake noise
  • Splash noise barriers for water impact noise
  • Minimal impact on cooling tower thermal performance
  • Suitable for new and retrofit installations
