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. If you chatted with someone, your speech would measure around 60 decibels on a sound-level meter.
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. Inside the room it's silent. So silent that the background noise measured is actually negative decibels, -9.4 dBA.
Public fascination with the room exploded 10 years ago, with an article on The Daily Mail's website. “The Longest Anyone Can Bear Earth's Quietest Place is 45 Minutes,” The Mail declared.
One good candidate is the Haleakalā crater on the Hawaiian island of Maui, which has been dubbed the “quietest place on Earth”. Here, the sound level is just 10 decibels – the same volume as your own breathing – and is probably as quiet as anything you can experience.
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.
If you stand in it for long enough, you start to hear your heartbeat. A ringing in your ears becomes deafening. When you move, your bones make a grinding noise. Eventually you lose your balance, because the absolute lack of reverberation sabotages your spatial awareness.
In a silence where some people could hear a pin drop, people with tinnitus hear a constant ringing in their ears. Or the sound may be a popping, rushing, pinging, chirping, whistling, or roaring.

That's what we learned from neuroscientist Dr. Seth Horowitz of Brown University; true silence is non-existent. "In truly quiet areas," he writes in his book, The Universal Sense, "you can even hear the sound of air molecules vibrating inside your ear canals or the fluid in your ears themselves."
It is located in the Plum Brook Station, a 6,400-acre campus near Sandusky, Ohio. The RATF's purpose is to test rocket parts, satellites and other space-related hardware to ensure that it can cope with the punishing noise of a rocket launch.
Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing. Exploding bombs, crashing asteroids, supernovas, and burning planets would similarly be silent in space.
UNILAD took on the challenge at London South Bank University's (LSBU) Anechoic Chamber, and now hold the unofficial world record! Rio Fredrika, one of UNILAD's presenters, spent 1 hour and 7 minutes in the chamber, which cuts out over 99% of all sound.
Members of the public must book a tour to visit the room, and are only allowed in for a short, supervised stay. According to the lab's website, only members of the media are permitted to stay in the chamber alone for prolonged periods of time.
The longest anyone can bear Earth's quietest place is 45 minutes. They say silence is golden – but there's a room in the U.S that's so quiet it becomes unbearable after a short time. The longest that anyone has survived in the 'anechoic chamber' at Orfield Laboratories in South Minneapolis is just 45 minutes.
Coming in first place is Bergen, Norway, ranked highly for its very low levels of traffic congestion (13%), low levels of light and noise pollution (25), and a high average life expectancy of 83 years.
I Kings 19:11-13). God speaks in silence, but we must know how to listen. This is why monasteries are oases in which God speaks to humanity; and in them we find the cloister, a symbolic place because it is an enclosed space yet open to Heaven.
Being silent allows us to channel our energies. It gives us the clarity we need to calmly face challenges and uncertainty. The hour of silence I practice each morning, and encourage you to practice as well, can be a time for collecting our thoughts, training our minds, and deciding how we want to enter into the day.
“Silence and periods of calm stimulate brain growth and relieve tension, which can result in a higher sense of well-being, as people can then feel more relaxed generally,” says Prunty. “When this occurs, sleep quality improves.”
But what about the loudest sound ever heard? On the morning of 27 August 1883, on the Indonesian island of Krakatoa, a volcanic eruption produced what scientists believe to be the loudest sound produced on the surface of the planet, estimated at 310 decibels (dB).
“Even if you are far from a road, you are not far from the roads in the sky,” he says. Unfortunately, Hempton says that there is absolutely no place on Earth that is completely free from human sound all of the time.
The quietest place on earth is an anechoic chamber at Orfield Laboratories in Minnesota. The space is so quiet that the longest anybody has been able to bear it was an entire 45 minutes. It is 99.99 percent sound absorbent and holds the Guinness World Record for the world's quietest place.
Black noise is a type of noise where the dominant energy level is zero throughout all frequencies, with occasional sudden rises; it is also defined as silence.
silence has its own voice which vibrates at a very lower frequency than verbal words...the voice of silence can be heard or perceived by those who have trained their inner man to perceive the inaudible. According to science, the range of audible voice or sound waves the humans can hear is between 20HZ and 20KHZ.
Summary: Phantom noises, that mimic ringing in the ears associated with tinnitus, can be experienced by people with normal hearing in quiet situations, according to new research.
