You've probably seen the headlines. They usually say something like "The Quietest Place on Earth Will Drive You Insane" or "Man Goes Crazy in Silence." It's great clickbait. It’s also mostly wrong.
The Orfield Labs quiet room—technically known as an anechoic chamber—is located in a nondescript building in Minneapolis. It isn't a torture chamber. It isn't a supernatural void. It’s an engineering marvel designed by Steven Orfield and his team to achieve a level of silence that feels, honestly, a bit heavy. When you step inside, you aren't just entering a quiet room; you’re entering a space that absorbs 99.99% of sound.
Most people think silence is the absence of noise. In this chamber, silence is a physical presence.
The room holds a Guinness World Record. At one point, it was measured at -9.4 decibels. To put that in perspective, a typical quiet bedroom at night is around 30 decibels. Because the decibel scale is logarithmic, we’re talking about a difference that the human ear struggles to even categorize. It is so quiet that the background noise of the room is actually lower than the threshold of human hearing.
What Actually Happens to Your Body in the Orfield Labs Quiet Room
The rumors say you’ll start hallucinating within minutes. That’s a stretch.
What actually happens is much more grounded in biology, but it’s still deeply unsettling. When you're in a normal room, your ears are constantly processing "floor noise"—the hum of the fridge, the distant rush of traffic, the sound of your own breath hitting the air. Your brain uses these cues to map the space around you.
In the Orfield Labs quiet room, those cues vanish.
Within a few minutes, your ears perform a sort of biological "gain control." They crank up their sensitivity. Because there is no external sound to find, they start looking for internal sound. This is where it gets weird. You start to hear your heart beating. Not just the thumping in your chest, but the blood rushing through your carotid arteries. You hear your lungs. You hear your stomach gurgling with a clarity that is, frankly, kind of disgusting.
The Balance Issue
Most people don't realize that we use our ears for more than just hearing; we use them to balance. We listen to the "sound" of a room to understand where we are in relation to the walls and floor.

Take that away, and your vestibular system starts to freak out. Visitors often report feeling dizzy or disoriented after just 15 or 20 minutes. Steven Orfield himself has noted that many people find it difficult to stay standing for long periods in the dark inside the chamber. You almost have to sit down to keep from tipping over because your brain is getting zero feedback from the environment.
How the Chamber Works (No, It’s Not Just Thick Walls)
Building the Orfield Labs quiet room wasn't just about using a lot of insulation. It's a "room within a room within a room."
The inner chamber is a six-sided steel box. It’s suspended on giant springs to isolate it from the vibration of the rest of the building. Even a truck driving by outside could ruin a measurement if the room were bolted to the floor. Inside that steel box, every surface—the walls, the ceiling, even the floor—is covered in three-foot-thick fiberglass acoustic wedges.
These wedges are the secret sauce.
When a sound wave hits them, it doesn't bounce back. It gets trapped in the fiberglass and dissipates as a tiny, tiny amount of heat. You’re actually standing on a mesh floor, sort of like a trampoline made of thin wire, so that the wedges can be placed beneath your feet too.
- Steel Mesh Floor: Suspends you in the middle of the acoustic treatment.
- Fiberglass Wedges: Arranged in a jagged pattern to break up sound waves.
- Double Steel Walls: To block out external electromagnetic and acoustic interference.
- Spring Suspension: To negate seismic vibrations.
The result is a space where sound doesn't echo. At all. If you clap your hands, the sound just... stops. It falls flat. It feels like the air is sucking the noise out of your mouth before you can even finish a sentence.
Why Does Orfield Labs Even Exist?
It’s easy to focus on the "going crazy" aspect, but this is a serious laboratory. Companies pay a lot of money to use the Orfield Labs quiet room for product testing.
Think about your dishwasher. Or your car dashboard. Or a heart valve.

Manufacturers want to know exactly what sounds their products make without any interference. Harley-Davidson has used the lab to analyze the specific "rumble" of their engines. Whirlpool uses it to make sure their appliances aren't annoying. NASA has sent astronauts there to see how they handle the silence of space, because being in a vacuum is effectively the same acoustic experience.
It’s about "sound quality," not just "quiet." Engineers want to isolate specific frequencies to see if a product sounds "expensive" or "flimsy." A car door closing with a solid thud is a designed sound, and you need an anechoic chamber to perfect that.
Debunking the 45-Minute Myth
The internet loves the idea that no one can last 45 minutes in the room. It makes for a great urban legend.
The truth is a bit more boring: people have stayed in there much longer. The "45-minute" figure actually came from a journalist who spent that amount of time inside and found it incredibly difficult. It wasn't a hard limit for all of humanity.
However, the psychological pressure is real. Most people find that the longer they stay, the more their brain starts to invent sounds. Tinnitus sufferers often find the room unbearable because their internal ringing becomes deafening when there’s no external noise to mask it.
Sensory Deprivation vs. The Quiet Room
It’s important to distinguish this from a sensory deprivation tank (like a float tank). In a float tank, you’re in water, which provides a physical sensation. In the Orfield Labs quiet room, you’re just in a very, very quiet, dark room. The lack of acoustic feedback is what causes the distress.
We are social, noisy creatures. We are evolved to live in an environment full of rustling leaves, wind, and voices. Total silence is an evolutionary red flag. In the wild, if everything goes dead silent, it usually means a predator is nearby. Your "fight or flight" system doesn't quite know what to do with the Orfield Labs quiet room, so it stays on high alert.
The Competition: Microsoft vs. Orfield
For a long time, Orfield Labs held the crown. Then, Microsoft built their own anechoic chamber in Redmond, Washington (Building 87).

Microsoft’s lab eventually clocked in at -20.6 decibels.
If you’re wondering how something can be "negative" decibels, remember that 0 dB is the "threshold of hearing." It's not the absence of sound; it's just the lowest level a healthy human ear can typically detect. Going below zero means you’re in a realm where only the most sensitive microphones can measure the vibration of air molecules hitting each other (Brownian motion).
Steven Orfield has contested the Microsoft record, arguing that the testing conditions weren't identical, but regardless of who "wins," both rooms offer an experience that is essentially the same for a human visitor: absolute, crushing silence.
Making Use of Silence in Your Own Life
You probably can't fly to Minneapolis and pay for a session in the Orfield Labs quiet room just for fun (though they do occasionally host tours). But the science behind the lab tells us something important about our daily lives.
We live in a world of "noise pollution." Constant low-level humming from electronics, traffic, and HVAC systems keeps our cortisol levels slightly elevated. You don't need a -9.4 dB room to feel the benefits of quiet, but you do need to actively seek out moments where your brain isn't processing artificial noise.
If you want to experience a "diet" version of the Orfield effect, try this:
- Find the quietest room in your house.
- Turn off everything—fans, computers, even the fridge if you're dedicated.
- Wear a pair of high-quality passive noise-canceling earmuffs (the kind used at shooting ranges).
- Sit in total darkness for 20 minutes.
You won't reach the "blood rushing through your ears" stage, but you will notice your heart rate slowing down and your senses sharpening.
The Orfield Labs quiet room reminds us that sound is a constant tax on our attention. When that tax is removed, we’re left with ourselves. And for many people, that’s the loudest thing of all.
Actionable Insights for Sound Management
- Audit Your Environment: Use a free decibel meter app on your phone to check your bedroom. If it's over 35 dB, you might be experiencing sleep disruption without realizing it.
- Embrace Soundscapes: If total silence is too jarring (which it is for most), use "pink noise" rather than white noise. Pink noise has more power at lower frequencies and mimics natural sounds like rain or wind, which the brain finds less "clinical" than the harsh hiss of white noise.
- Protect Your Ears: The sensitivity increase experienced in anechoic chambers is a temporary version of what happens when we lose our hearing. Once the fine hairs in your inner ear are damaged by loud noise, they don't grow back.
- Practice Active Listening: Try to isolate sounds in a busy park. It’s the opposite of the quiet room experience but uses the same neurological pathways to improve focus and cognitive processing.
The Orfield Labs quiet room isn't just a place to break records. It's a reminder of how much the world shouts at us every day—and how strange it feels when the world finally shuts up.
