Ashburn/Loudoun resident here, lived right next to us-east-1 for 10+ years. No, the noise is not impactful. The data centers are very quiet on the outside. More noise comes from Dulles Airport nearby. Main problem is 1. visuals. They are horrendous blobs to look at. 2. land/electricity values. Gone up a lot in the past few years. Happy to answer any questions.
Also live near the data centers. While I'm obviously not 100% sure, I think that blue one is on Glenn Dr - for a bit of context, that is less than 3 miles (drive) from the Dulles International Airport. I'll see if I can record a video of the sound later tonight.
Well noise drops off following an inverse square law, so possibly everyone. Moving down just a couple houses can significantly cut down on noise pollution.
The direction of wind and shape of terrain has a huge effect on noise, too. If a noise source is down wind of you the gradient in wind speed wrt elevation effectively makes the noise curve upwards, and even very loud things can sometimes be inaudible at ground level.
These things are ugly and take up a lot of space. They do have their fans which claim they do not generate that much traffic relative to their size since, they don't have that many people working there. For example, if they were replaced with the same sized office buildings, they'd probably put more strain on the road infrastructure and so on. Also, some of the property taxes collected from DC operators supposedly go to lowering the property taxes of residents in the county.

“The décor of the machine room is unmarred by ornament. The room was created by walling off an area of the underground parking garage of a suburban Virginia office tower.

Standing in this crowded space, surrounded by hard-working and very slightly grungy machinery, gives an interesting perspective and sense of scale, which is exactly what I was looking for in coming here.

It's sad seeing people impacted by these data centers considering how little voice they have. I don't think anyone wants to live near a data center unless they actually worked there.
Much better than living next to a chemical plant. I thought the article and video were grasping at straws to find negative impacts. There’s no pollution on site so they have to talk about sounds that can’t be heard on the video and electrical poles.
I think this is dangerously close to NIMBY territory. People who bought homes in the cheapest land possible in areas with ample available farmland are upset that someone else bought some other land.
It’s quite easy to avoid that if you aren’t just buying on pure dollars per square foot like so many suburban buyers seem to be doing.
When it comes to vibrant urban core you actually benefit by having a lot of different things nearby “in my backyard.” As an added bonus, businesses looking for cheap land for factories and data centers tend to stay away.
But if we live in the city we’ll be “on top of each other” and I won’t have a walk-in closet to store all my clothes I don’t wear, and I won’t have a garage to store the car that I’m required to own to get around because nothing is nearby me, and I need a shed for my lawn mower because I can’t just share with my neighbors and I need my own yard because the public park is too far away, etc etc.
Since 2017, Louden County housing prices have gone up 59% according to Zillow. To put that in perspective, NYC is up 24%, LA up 56%, Chicago up 28%, SF up 7%, DC up 10%, Boston up 29%, Atlanta up 48%.
Ashburn, which is where the majority of the data centers are in Louden County, is up 56% so even when you look at a smaller area around the data centers, it doesn't seem to have harmed property values.
Even if you look at mansions on an acre of land a couple houses down from a data center, it looks like they've gone up in value at least as fast the average for both Louden County or Ashburn (https://www.zillow.com/homedetails/44335-Oldetowne-Pl-Ashbur... this place I randomly looked up is up around 70% according to Zillow).
It doesn't look like it's impacted housing prices negatively. That doesn't mean it doesn't impact how some people care about their homes. Some people might prefer to pay higher taxes than look at a data center across the street. But it isn't economically hurting residents. Their property taxes are very low, they have the highest median income in the US, and their property values are going up faster than most.
And very few people work there relative to the impact. Sure nobody liked living near factories in ye olden days, but they did like the employment opportunities.
You can see how few work there when you compare the size of the data centre and the size of the car park.
I don't think that the data centers are having a negative economic impact on Louden County residents. It's the richest country in the US with a median household income of $156,821. They also get really low property tax rates because the data centers are paying a lot of taxes compared to their costs. If there were lots more people working there, the county would need to spend a lot more money on roads and such. Instead, they're getting close to free money.
I'm not saying that anyone should want data centers to take over their city/county, but there isn't a strong economic argument against them in Louden County. The people there are the richest in the US and they're getting great economic benefits from it. The question isn't economic. The question is whether that's the community they want to live in: rich and making lots of money off data centers or an area where they don't have as much money and don't have to look at the data centers.
But there is an upside to this - you get the benefits of being a city with big business (tax revenue, donations to the local schools, investments in infrastructure), but don't have increased commuter traffic.
Are those benefits the norm in most cases though? I'm genuinely asking and don't know either way, but the companies building these data centers have quite a reputation for aggressively pursuing subsidies and tax avoidance strategies. Amazon for one has paid little to no federal taxes some years and they wouldn't be my first pick as an example of a magnanimous corporate entity, to say the least.
Whatever benefits there are have to be weighted against the very real costs. Residential power bills spiking is a hugely regressive burden for many struggling households.
Did you read the article? It's about Loudoun County, the wealthiest county in the US. The people "affected" both are the ones making the decision about where to put the data centers and the ones profiting off them. Don't lose sleep.
Also, those same people have the most ability to live wherever they want, and can leave. This isn't mountaintop removal in coal country. This is wealthy DC lobbyists being a little annoyed about a hum.
The fact that there's even an article about it is evidence of the fact that the affected are wealthy. The article is their voice. The wealth that allows them to live in Loudoun County is their voice.
I hadn't heard of Loudoun County before. I also did read the article and here's a sentence from it.
> But while most locals the BBC spoke to opposed the data centres, the industry has many powerful proponents, including US President Donald Trump.
Also moving isn't something to take lightly.
> "I never thought that a data centre would be built across the street from my house," she said. "I would not have bought this house if I had known what was going in across the street."
> "I never thought that a data centre would be built across the street from my house," she said. "I would not have bought this house if I had known what was going in across the street."
and let this be a lesson to anyone looking to buy with vacant land within whatever radius you want to apply. if you think you might be upset by something that could be developed in the future, you can do some basic research on what zoning the lot(s) have, if they are owned by someone/thing that is discernible and not a shell company (if it is a shell company that's probably an indication you won't like what's coming), etc. sure, the ultimate developer of the think you won't like might only purchase the lot just before they are ready to build (specifically to avoid this), ultimately they will have to file for plans. it's possible those plans have already been filed, but if you don't look into it, it's really on you since you have the problem with it.
If I'm correct that the data center shown is on Belfort and Glenn Dr, then you don't even have to "research" zoning, just look across the street.
In 2021/2022 before it was built:
* Here is what that lot looked like [1]. To assume something wouldn't be built there is optimistic at best. (And there was precedent for data centers at the time - there was already a data center less than half mile away on Vantage Data Plz across the street from Tart Lumber.)
* If you look across the street, ie if the video would have panned to the left, you would have seen the "US Customs and Border Patrol" building - not winning any architectural design awards [2].
For someone who bought their house decades ago, then yes - the area has transformed drastically. But grouping someone who purchased recently with someone who purchased decades ago is a bit muddled.
The best research one can do is only going to be so useful. Zoning laws might stop an average person or corporation from building something undesirable, but entities with enough wealth and connections can get those changed. Lately the conventional wisdom seems to be that NIMBYs have too much power, but in all of the cases I'm personally familiar with a single wealthy person or corporation was able to re-zone property however they wanted over the overwhelming objections of the longtime residents nearby.
I was imagining hearing the bird-chirping-like beeps of thousands of PCs constantly rebooting, since some subset is always in the process of restarting. Probably not audible outside.
Article makes a huge deal about humming/buzzing but there’s no way that’s a real thing right? What would be the reason it would go beyond like any HVAC-ish thing on a large building? Lost me at the first sentence :(
I live close to a hospital and they make a generator test run once a month. That's an ultra deep sinus (~30Hz) that's humming along - you can hear it everywhere within the city.
It's was super easy to measure using a Sensirion Differential Pressure sensor. They have a few extremely sensitive models that have a 100Hz sampling rate (50Hz useable after Nyquist) - also: you can sense washing machines (from vibrating buildings) with it 2 blocks away.
Due to rising power densities, and constrained power and costs of that power, modern data centers tend to use free air cooling vs the older always compressor cooling. When the temperatures are right they basically just use fans to bring outside air in, which is much much louder because you have to move a lot of it.
It goes way beyond normal building HVAC levels, AI has pushed many DC's from 8 kW to 17 kW a rack in just a few years.
IIRC the average medium office building pulls about 22 kilowatt-hours (kWh) per square foot of floorspace per year. So their cooling needs are tiny.
> It goes way beyond normal building HVAC levels, AI has pushed many DC's from 8 kW to 17 kW a rack in just a few years.
17 kW per rack for AI/ML HPC was workable >5 years ago. If you're not budgeting for double or triple that number nowadays you're not capacity planning properly.
I worked in a medium data center and there was no noise outside, no noise from the office in the same building, no noise outside the airlock, very loud inside.
Maybe huge datacenters are very different somehow?
Scale; comparing DC cooling to a large building's is like comparing street noise in a suburb to a highway.
It'd be nice to have some hard data on it though. Sometimes the hum is "god damn, that is annoying!" and other times it's someone saying "20 miles that way they built a DC and now it makes the cell phone tower effects twice as bad in this area" when reality was it doesn't show up as audible a half mile away.
I once visited a fairly large DC in the outskirts of paris (Scaleway DC5) and it was basically dead silent outside. I guess these large DCs are just build with absolutely no concern for noise pollution?
Scaleway DC5 is large by French standards, rather small by US hyperscaler standards. But the main reason is DC5 does not use classic cooling, thus does not have huge dry coolers outside, which definitely helps for noise (it's adiabatic cooling).
Another fact is just the sheer power density of those problematic north virginia datacenters. I'd bet us-east-1 is not an issue (old building and lower power density), but the newer AI ones are. Just take a look at how much AI clusters eat: a single DGX H200 box with 8 GPUs is 10kW. Most facilities provide 10kW for a whole rack, not 8Us. You're looking at 60kW racks, which is a mental power density: a single aisle trivially gets over the MW threshold. You used to feed rooms with megawatts. Heck, DC5 has 24MW of power, that's only 20000 H200 (again, think hyperscaler scale).
Still about cooling, the load profile is even different. DC5 is a general purpose datacenter, where the load is not full blast. Your AI datacenter has the GPU clusters full blast all the time. That's a LOT of power.
I happen to know pretty well the Scaleway infra and visited others of their datacenters. You can stand centimeters from the noise-dampening wall surrounding the dry coolers and not hear a thing; while almost needing noise protection within the wall.
I have never visited datacenters that large, but transformer substations can have an audible hum to them. Tests of diesel generators can also produce a bit of noise.
I'm fairly surprised that there aren't zoning laws that prevents datacenters from being built where people live. When we built a fairly small datacenter we had to place it in an industrial area with no housing and no offices.
If got past the first sentence, you might learn the answer to the question. Substations and power/peaker plants. Maybe not in all cases, but I wouldn't want to live next a building have has row upon row of AC systems running 24 hours a day.
> Article makes a huge deal about humming/buzzing but there’s no way that’s a real thing right?
There's going to be variation based on how the data center is constructed.
The ones I've seen (which is certainly not all of them, so take it with a grain of salt) in the geographic area that this particular article is about are closed buildings that should be pretty well noise regulated individually, but that's not always the case -- some companies (like Marathon/MARA) have data centers using what are effectively open air designs that don't contain sound very well at all and can easily generate significant noise pollution around them.
And some companies (eg. xAI/grok) are a bit of a hybrid where the main part of the data center is enclosed but they park many loud methane turbines outside of the building for power and those make a lot of noise (and air pollutants).
The basic TL;DR is that it is possible to build data centers that aren't an absolute nuisance to the population around them, but there are plenty of data centers out there that don't meet that goal. And the more these companies try to scale up quickly to meet their perceived "AI" needs, the worse things are getting in terms of noise pollution, air pollution and competing for resources (like water and energy) with local residents, etc.
Nobody in this article is whining about a company "building something". But whenever anything this large is built, there are externalities. Externalities are an indirect cost or benefit to others.
It just seems to me that in Virginia in the United States, the externalities of building a massive data centre in an existing residential zone are either not being considered or not being acted upon.
I'd hate it if a company built a massive data centre right next to where I sleep. Low noise pollution is vitally important to quality of life.
I'd like to live in a society that treated me fairly, and at least purchased my property off me before building the data centre.
By all means, build the infrastructure. But please look after your people. It's not that arduous to purchase a few properties in exchange for a massive amount of profit.
It is a human interest story so it focused on that angle. I think most people can recognise that having these data centres on US soil outweighs the quality of life concerns of the local residents. NIMBYism holds back a lot of infrastructure in the UK, that does get discussed a lot here.

I imagine trees and fields that have been cleared and the roads paved probably play a good part as well.

I already live and sleep next to my homelab, which is probably louder than those power plants
> Article makes a huge deal about humming/buzzing but there’s no way that’s a real thing right?
There's going to be variation based on how the data center is constructed.
The ones I've seen (which is certainly not all of them, so take it with a grain of salt) in the geographic area that this particular article is about are closed buildings that should be pretty well noise regulated individually, but that's not always the case -- some companies (like Marathon/MARA) have data centers using what are effectively open air designs that don't contain sound very well at all and can easily generate significant noise pollution around them.
And some companies (eg. xAI/grok) are a bit of a hybrid where the main part of the data center is enclosed but they park many loud methane turbines outside of the building for power and those make a lot of noise (and air pollutants).
The basic TL;DR is that it is possible to build data centers that aren't an absolute nuisance to the population around them, but there are plenty of data centers out there that don't meet that goal. And the more these companies try to scale up quickly to meet their perceived "AI" needs, the worse things are getting in terms of noise pollution, air pollution and competing for resources (like water and energy) with local residents, etc.
god forbid someone builds something. it is very fitting that a british newspaper would be so repulsed by the prospect of industry.
Nobody in this article is whining about a company "building something". But whenever anything this large is built, there are externalities. Externalities are an indirect cost or benefit to others.

It just seems to me that in Virginia in the United States, the externalities of building a massive data centre in an existing residential zone are either not being considered or not being acted upon.
I'd hate it if a company built a massive data centre right next to where I sleep. Low noise pollution is vitally important to quality of life.
I'd like to live in a society that treated me fairly, and at least purchased my property off me before building the data centre.
By all means, build the infrastructure. But please look after your people. It's not that arduous to purchase a few properties in exchange for a massive amount of profit.
It is a human interest story so it focused on that angle. I think most people can recognise that having these data centres on US soil outweighs the quality of life concerns of the local residents. NIMBYism holds back a lot of infrastructure in the UK, that does get discussed a lot here.
