Cooling Tower Noise Reduction

Cooling tower noise is one of the more common challenges on commercial and industrial sites, particularly where towers are located close to occupied buildings, neighbouring properties, or areas subject to planning noise conditions. It’s a practical issue with practical solutions, and it’s something we can address directly as part of a new build or an upgrade to an existing system. 

Can You Make a Cooling Tower Quieter?

Yes, we offer a range of sound attenuation solutions to minimise noise from the inlet, outlet, and breakout areas of the cooling tower. 

Noise from a cooling tower typically comes from three main sources: the air inlet, the air outlet, and breakout noise through the casing itself. Addressing all three effectively requires solutions that are designed around the specific tower and its operating conditions, not a generic off-the-shelf approach. 

Where Cooling Tower Noise Comes From

Understanding the source of the noise matters before specifying a solution. The three main areas are: 

• Inlet noise, generated as air is drawn into the tower by the fan system 
• Outlet noise, produced as air is discharged from the top or sides of the tower 
• Breakout noise, which radiates through the tower casing and panels rather than through the air openings 

Each of these requires a different attenuation approach, and in many cases more than one source needs to be addressed to achieve a meaningful reduction in overall noise levels.

Sound Attenuation for New and Existing Cooling Towers 

Franklin Hodge supplies sound attenuation solutions for both new Carter Environmental cooling towers and Visco cooling towers, as well as existing systems that require noise reduction as part of a refurbishment or compliance upgrade. 

For existing towers, noise attenuation can often be incorporated without requiring full replacement. Our team can assess the tower and identify where attenuation will have the greatest effect. Where a more comprehensive upgrade is needed, this can be combined with our cooling tower refurbishment service to address noise and condition at the same time. 

Why Cooling Tower Noise Reduction Matters 

Noise complaints and planning conditions around cooling tower noise are increasingly common, particularly on urban sites and those adjacent to residential areas. Getting this right is important for: 

• Meeting planning permission conditions and local authority noise requirements 
• Avoiding complaints from neighbouring occupants or businesses 
• Maintaining a safe and compliant working environment on-site 
• Protecting the long-term operation of your cooling system without restrictions

Speak to Franklin Hodge About Cooling Tower Noise

If noise from your cooling tower is an issue, or if you’re specifying a new system where noise levels need to meet particular requirements, our team can discuss the appropriate attenuation options for your site. View our full cooling towers range or get in touch to discuss your requirements.

Frequently Asked Questions

Can sound attenuation be added to an existing cooling tower? 

In many cases, yes. Attenuation solutions can be fitted to existing towers to reduce noise at the inlet, outlet, and breakout areas without requiring full system replacement. 

What areas of a cooling tower produce the most noise? 

The three main noise sources are the air inlet, air outlet, and breakout noise through the tower casing. Effective noise reduction typically involves addressing more than one of these areas. 

Does Franklin Hodge offer noise reduction for both Carter Environmental and Visco cooling towers? 

Yes, sound attenuation solutions are available for both Carter Environmental and Visco cooling tower systems. 

Can cooling tower noise reduction be combined with refurbishment? 

Yes, noise attenuation work can be carried out alongside a full cooling tower refurbishment where the system requires broader attention.
