This is what happened to the man who spent the longest time in quietest room in the world

Many of us might like a bit of peace and quiet from time to time, but as with most things, sometimes there is something as too much.

It's so quiet in fact that visitors are advised to spend no more than 45 minutes inside if they can last that long.

One man, however, took things even further than that when he visited the anechoic chamber at South Bank University in London.

The chamber is designed to cancel out as much sound as possible and is so well insulated that popping a balloon barely even registers.

In fact it's so quiet the sound is measured in negative decibels.

Scientist Steven Orfield designed the chamber and explained why people are advised to spend no more than 45 minutes inside: "We challenge people to sit in the chamber in the dark. When it's quiet, ears will adapt. The quieter the room, the more things you hear.

"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."

Of course where there's a challenge there's someone brave, or foolhardy, enough to push the boundaries.

Enter YouTuber and musician Callux, who set a new world record for spending time inside the chamber, at the time this was 67 minutes.

He made a video showing how the challenge went for him, and gave a description of the rules as well.

The YouTube had to follow these for the challenge to count for the Guinness Book of World Records.

This is what the rules were:

1. The challenger must be alone in the chamber.

2. No sleeping/fainting is allowed.

3. The challenger must be monitored and remain under constant supervision at all times.

4. Sound must stay below 25DBa.

5. The challenger is permitted to speak for up to one minute every five minutes.

6. The challenger is permitted to leave at any time.

7. Optional - the challenge must be completed in the dark.

After spending just five minutes in the room, he reported feeling disoriented after experiencing an intense wave of tinnitus in both of his ears.

After 15 minutes, he said that he could see lights dancing round him, and after half an hour, he claimed that he could hear his own blood flowing round his body.

As he neared the one hour mark, Callux almost gave up just short of the world record, claiming he was having hallucinations in the room.

But he didn't give up, and continued on to break the world record and setting a new one of one hour and 26 minutes.

Summing up his experience, Callux said: "That was f**king weird."
