So, in order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate. There is no sound there.
In the anechoic chamber, speech sounds very muffled, like when your ears need to pop in an airplane. According to the Guinness Book of Records, the anechoic chamber at Orfield Laboratories in Minneapolis is the quietest place in the world, with a background noise reading of –9.4 decibels.
The quietest place on earth, an anechoic chamber at Orfield Laboratories in Minnesota, is so quiet that the longest anybody has been able to bear it is 45 minutes.
1. Building 87, Washington, US: The place defined as “where sound goes to die” is at the top of our list of the world's quietest places. According to Guinness World Records, this Microsoft research lab in Redmond, Washington, is the quietest place on the planet.
The world's quietest place
Brüel & Kjær and BlackHawk Technology Inc. measured the noise floor of Microsoft's quietest anechoic chamber at –20.6 dB(A) SPL. The quietest level of noise theorized by mathematicians is Brownian motion – the movement of particles in a gas or liquid – at –23 dB.
Typically, zero decibels sound pressure level (SPL) corresponds to 0.000002 Pascals — a measure of vibration or pressure waves that we really hear. So then, zero decibels is the smallest level of sound our ears can detect!
A physicist will say there is no such thing as “absolute” silence. The lowest sound level in the natural world is that of particles moving through gas or liquid, known as Brownian motion.
Orfield Laboratories offers tours of our facility focused on its earlier incarnation as Sound 80 Studios "The World's First Digital Recording Studios" and the later addition of our acoustic labs and our world famous Anechoic Chamber, "The Quietest Place on Earth." These tours run from a one and a half hour minimum and ...
Green Bank sits within the National Radio Quiet Zone (NRQZ), which is a 13,000-square mile area in the eastern half of West Virginia, part of Virginia, and a sliver of Maryland.
Steve Orfield explained: “what the chamber tends to do is it tends to scare people because when you get in the chamber, everything gets tremendously quiet. You feel like there's pressure on your ears – but it's actually pressure moving away from your ears.
Meanwhile, another anechoic chamber is hoping to earn the new title of the quietest room in the world. Located at Orfield Laboratories in Minneapolis, the room achieved “a legitimate measurement” of “–24.9 dBA,” according to Steven J. Orfield, who designed the space. It had previously held the record.
Sound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
The entry fee is $200 per person, with a $400 minimum. There's also an option to reserve the chamber for $600 an hour in order to take the Orfield Challenge and see how long you can last. As of June 2022, the record to beat is two hours.
"The longest continuous time anyone has spent inside the chamber is about 55 minutes," confirmed Gopal at Microsoft. "I have noticed that there are several folks who can stay inside for 30 minutes or so. But others have asked to go out within the first few seconds." Global Privacy Control (GPC) signal detected.

The brain creates noise to fill the silence, and we hear this as tinnitus. Perhaps only someone with profound deafness can achieve this level of silence, so paradoxically loud.
When you practice solitude and silence, you allow your brain to process your emotions, rather than suppressing them and remaining on autopilot. You may feel some uncomfortable emotions through this process, but the sooner you recognize and address your feelings, the sooner you can move forward in health and freedom.
If you are bothered by a high-pitched sound, buzzing, or shushing in one or both ears, you may have a condition called tinnitus, which effects a majority of the population at some point in their lives.
Virtually everyone will experience some tinnitus from time to time throughout their life. Have you ever left a concert or sporting event with a high-pitched ringing in your ears? This is called tinnitus. Virtually everyone will experience some tinnitus from time to time throughout their life.
Unpleasant sounds are between 2,000 to 5,000 Hz frequency range. After analyzing all the sounds the participants liked and hated, and placing them in order of unpleasantness, the researchers found that disagreeable sounds tend to be between the frequency range of about 2,000 to 5,000 Hz.
Common Sources of Noise and Decibel Levels
A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
Outer space is not completely empty; it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.
Sound waves need a medium to travel. As there is no atmosphere or medium on the moon, that's why no sound can be heard on the moon. Astronauts use radio waves while talking to one another on the surface of the moon.
