How to diagnose the reasons fans cause noise complaints
Fan noise is by far the main cause of environmental noise complaints from residents living near industrial sites. This guide explains why this is the case, the main types of fan, how the noise is generated, and the optimum approach to finding solutions to fan noise problems.
A common and costly mistake when assessing fan noise problems is to not diagnose the precise contributions from broadband and tonal noise features to the issue. Just how common a mistake is highlighted by the fact that 95% of consultant noise reports are inadequate, a major cause of which is poor (or no) diagnosis.
The guide provides an accessible, detailed explanation of the types of fans and their noise characteristics to aid with defining and solving fan noise problems.

The Fundamentals of Fan Noise
What are the fan noise control options - examples of best practice in action
Fan silencing can be very expensive, not just the capital cost, but also the cost of the downtime required to fit and the running cost increases if the attenuation reduces efficiency. In addition, most conventional silencing projects assume that the broadband dB(A) is the only criterion, whereas the cause of the noise issue may well include tonal noise (hums etc). As a result, the recommended attenuation often does not solve the problem (95% of noise reports are inadequate).
Where both characteristics are issues, removing tones using modern aero-technology means that very much smaller (and cheaper) silencers can be used, or alternatively, existing system ductwork can be made acoustically effective retrospectively.
Optimum solutions for any fan noise issue
This approach not only cuts typical fan noise control project costs by 50% - 80%, but it also guarantees that the problem will be solved as cost-effectively as possible. The guide presents a selection of case studies that provide examples of the best approach and the techniques that can be used to solve all types of fan noise problems.

The Best Ways to Solve Your Fan Noise Problem
Data centres (or “data centers” in the USA) are being built in ever increasing numbers across the world to provide the increasing digital services, including AI. These installations include crypto mining facilities and energy centres. As they are noisy, there is a tsunami of complaints about data centre noise in the environment.
This guide explains the major sources of the noise issues and the optimum cost-effective approach to both solve noise problems and, in many cases, to reduce power consumption by improving efficiency. Example case studies are given in the follow-up guide “How to Fix your Data Centre Noise Problem”.
This guide provides example case studies that demonstrate how data centre noise problems van be resolved.

How to solve fan noise problems remotely via smartphone
For most fan noise problems, we can get the diagnostic information we need to identify the precise cause(s) to evaluate the noise control options via smartphone data. No site visit is required.
This free service gives you access to a worldwide fan noise control solutions database that reduces typical project costs by 50% - 80%. Once the smartphone analysis is complete, we email you the costed noise control best practice options.
Subsequently, we can provide detailed solutions for implementation by local contractors. This guide explains how to access this service and provides details of the information that we need.
