Data centres are often presented as the backbone of the digital world. They power cloud computing, AI, streaming, banking apps, online shopping and almost everything connected to the internet. India is now witnessing a rapid rise in data centre construction. Cities like Mumbai, Chennai, Hyderabad, Noida and Pune are becoming major hubs.
But there is another side to this digital boom. People living near some data centres across the world say they are being forced to live with a constant humming noise, day and night.

What is this humming noise?
Data centres run 24/7. Thousands of servers inside these buildings generate huge amounts of heat. To stop the systems from overheating, massive cooling systems, industrial fans, backup generators and ventilation units work continuously. These machines create a low-frequency humming or buzzing sound. It may not always be extremely loud, but the problem is that it never stops.
Imagine hearing the same distant engine sound every minute of every day. Over time, that constant vibration can start affecting sleep, concentration and mental peace.
Some residents living near data centres in countries like the UK and the US have complained that the noise feels worse at night, when everything else becomes quieter.

India’s data centre boom could create new challenges
According to industry estimates, India’s data centre market is expected to expand rapidly over the next few years. But are Indian cities prepared for the side effects?
Many data centres are being built close to urban areas because companies want low latency and better connectivity. This means residential neighbourhoods could end up very close to large server facilities.
In crowded cities, even a small increase in noise pollution can make life uncomfortable. And this is not the only concern linked to data centres.
It is not just noise. There is also the water problem
Data centres need enormous amounts of water for cooling. In fact, this connects directly to another growing debate in India- whether data centres could worsen water scarcity in already stressed cities.
Previously, I wrote about data centres linked to water shortages. Now add constant noise pollution to the equation. The question becomes bigger: are cities sacrificing long-term liveability for digital growth?

As India races to become a global digital powerhouse, the country may also need to ask a difficult question:
How much environmental and human discomfort are we willing to accept in exchange for a fully connected digital future?
