Although an hour in the world’s quietest chamber may seem like pure heaven to some, it isn’t as peaceful as you might assume.

The Anechoic Chamber at London’s South Bank University is so quiet that even the tiniest sound your body produces is noticeable.

We’re not simply talking about listening to your stomach rumble in hunger or your joints click as you walk.

Those who are courageous enough to enter one of the world’s quietest chambers may virtually hear their blood flowing around their bodies because it is so deafeningly quiet.

As anticipated, this peculiar encounter could significantly influence individuals, given that the majority of us are used to constant commotion instead of absolute silence in an echo chamber.

In 2019, YouTuber Callum McGinley, also known as ‘Callux’ online, decided to take one for the team and visit the specialty facility in the UK capital.

After spending an hour and twenty-six minutes inside, he summarized his thoughts with a single comment: “That was incredibly strange.”

The 32-year-old aimed to break the previous Guinness World Record for the longest duration spent in the Anechoic Chamber, which was 67 minutes.

To do so, he needed to remain cognizant and awake during the difficult endeavor, and he could only talk for 60 seconds every five minutes.

We did this to keep the chamber’s sound levels at 25 decibels, the same volume as human breathing.

Despite his efforts, Callum soon succumbed to the disorienting effects of the extremely silent chamber.

Within five minutes of being in there, he reported feeling disoriented and suffering a strong blast of tinnitus in both ears.

Callum then complained of ‘pressure in his head’ and claimed to see lights dancing about him in the room around the 15-minute mark.

After around 30 minutes, the strange effects began to impact the content producer, who was startled by the sound of his own blood rushing through his veins.

“The sound I thought was the London Underground earlier, that’s my blood traveling around my ear,” he said.

“The sound is akin to someone dragging a trolley across my ear, and I am experiencing a sensation of time slowing down as I speak.”

Callum then informed the camera that ‘things began getting a bit odd,’ to the point that he pondered abandoning the challenge due to hallucinations he was experiencing.

He stated, “I was trying to follow this thing I was imagining around the room.” It terrified me and brought tears to my eyes, but I knew I just had a few minutes left to break the world record.

“All I had to do was hang in there for a couple more minutes.”

This is precisely what he achieved, even though it proved to be the ‘hardest’ aspect of the task—dethroning the former world record holder and claiming the title for himself.

He established an astonishing new record of one hour and 26 minutes…despite the fact that the man who created the Anechoic Chamber does not advocate spending more than three quarters of an hour in it.

Steven Orfield stated of the strangely silent room, “We challenge people to sit in the chamber in the dark.”

“When it is quiet, ears will adjust. The quieter the environment, the more you can hear.

“You will hear your heart beating, your lungs occasionally, and your stomach gurgling loudly.” In the anechoic chamber, you are the sound.”

South Bank University designed the Anechoic Chamber to “produce virtually ideal silence circumstances.”

This is accomplished because ‘external sound is not permitted to break in, and sound reflections off internal room boundaries cannot occur.’.

However, it is not the only mind-bendingly silent chamber on the block; there is another at Orfield Laboratories in Minneapolis, Minnesota.

So, whichever side of the water you are on, you may try to break Callum’s astounding record…if you dare.
