Horrifying side effects man experienced after 86 minutes in world’s quietest room where you can hear your own organs

Imagine a room so quiet you can hear your own blood flowing through your veins. For YouTu

ber Callum McGinley, better known as Callux, this wasn’t just a thought experiment—it was a reality. In 2019, Callum entered the Anechoic Chamber at London’s South Bank University, one of the world’s quietest rooms, to beat the Guinness World Record for the longest time spent in such an environment. But what started as a challenge quickly turned into a bizarre and unsettling experience.

The Anechoic Chamber is designed to eliminate all external noise, creating an environment where even the slightest sounds become deafeningly clear. Within minutes of entering, Callum began to feel the strange effects of absolute silence. “That was f***ing weird,” he said after spending an hour and 26 minutes inside.

The YouTuber, who aimed to surpass the previous record of 67 minutes, had to stay conscious and awake while speaking only 60 seconds every five minutes to keep noise levels below 25 decibels—about as loud as breathing. But the silence took its toll almost immediately. Within five minutes, Callum felt spaced out and experienced intense tinnitus in both ears. By the 15-minute mark, he reported feeling pressure in his head and seeing lights dancing around the room.

The real challenge came at the 30-minute mark, when Callum became unnerved by the sound of his own blood circulating through his body. “The sound I thought was the London Underground earlier, that’s my blood traveling around my ear,” he said. “It sounds like someone’s dragging a trolley across my ear.”

As time went on, the effects grew even stranger. Callum began hallucinating, imagining shapes moving around the room. “I was trying to track this thing I was imagining around the room. It was freaking me out and brought tears to my eyes,” he admitted. Despite the discomfort, he pushed through to beat the record, describing the final minutes as the “hardest” part of the challenge.

The Anechoic Chamber, built to achieve near-perfect silence, is made of heavy concrete walls, long foam wedges, and soundproof doors. Steven Orfield, the designer of a similar chamber in Minneapolis, warns that spending too much time in such an environment can be disorienting.

“When it’s quiet, ears will adapt. The quieter the room, the more things you hear,” he explained. “You’ll hear your heart beating, sometimes you can hear your lungs, hear your stomach gurgling loudly. In the anechoic chamber, you become the sound.”

Callum’s record-breaking experience highlights just how unsettling absolute silence can be. While the Anechoic Chamber offers a unique opportunity to confront the sounds of your own body, it’s not for the faint of heart. As Callum proved, even 86 minutes in the world’s quietest room can feel like an eternity. Would you dare to take on the challenge?
