Acoustic Challenges & Modern Data Centres
Welcome to the first instalment of Building Better Neighbours, a new series exploring design choices that can help data centres become more welcome within their local communities.
As data centres continue to grow in size, number and power demand, they are increasingly being built in locations they have not occupied before – closer to homes, schools and commercial areas. Today’s facilities are effectively AI factories, driven by unprecedented GPU‑based workloads that require substantial electrical capacity, advanced cooling systems and continuous airflow. This rapid growth is colliding with community expectations for liveable, attractive and quiet environments.
In response, cities and local authorities are introducing stricter zoning requirements, increased scrutiny and evolving noise regulations. This often leaves architects and engineers searching for practical ways to ensure data centres are not only compliant, but also accepted within their surroundings.
This series explores practical, design‑led approaches to creating facilities that perform at hyperscale while integrating more effectively with the communities around them. We will examine real site challenges and highlight product solutions that support airflow, aesthetics and, in this first instalment, sound attenuation.
The cloud is loud
Noise is one of the most significant points of tension when data centres are located near residential or mixed-use develoments. Plant areas typically house cooling towers (85–95 dB), generators (90–100 dB) and transformers (70–80 dB) – levels well above the 55–65 dB often permitted in residential settings. Local regulations can become even more restrictive between 10 p.m. and 6 a.m., with reductions of 10 dB or more commonly required in dense or mixed‑use environments. Without effective mitigation, these facilities can trigger complaints, regulatory challenges or costly design modifications. The risk of downtime can quickly become a major concern for developers.
Why is noise challenging?
Generator enclosures and cooling systems produce broadband sound across multiple octave bands. As a result, effective noise mitigation depends on addressing the specific frequrency ranges involved. Noise also tends to refract and travel further at night, while many data centre sites lack natural mitigation such as large setbacks, established vegetation or surrounding buildings that provide acoustic mass. This makes engineered solutions essential from the outset.
Acoustic louvres and screens
Acoustic louvres are well suited to addressing two key challenges in data centres: airflow and sound control. They can be integrated into façades or installed as freestanding screens on rooftops or around equipment. Unlike solid walls, which can restrict ventilation, acoustic louvres maintain essential intake and exhaust airflow while reducing sound transmission.
These systems are designed to perform differently across octave bands, allowing architects to target attenuation to the specific frequencies generated by cooling towers, generators or gas turbines.
At CS, we offer a range of Acoustic louvre solutions designed to meet the demanding needs of data centres in particular. Where retrofit solutions are needed, rather than removing existing screening structures and replacing them entirely, we can help you explore how acoustic solutions can be integrated into the current design.
Looking (and listening) ahead
As data centres continue to expand and move closer to urban and residential areas, noise mitigation will remain fundamental to achieving community compatibility. Acoustic louvres and screens provide a high‑performance solution that helps facilities meet regulatory requirements while reducing impact on surrounding envionments.
We are always listening (no pun intended) and ready to develop better solutions. Bring CS your ideas – we would welcome the opportunity to collaborate on improving outcomes for your data centre projects.
