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.
The longest that anyone has survived in the ‘anechoic chamber’ at Orfield Laboratories in South Minneapolis is just 45 minutes.
It’s 99.99 per cent sound absorbent and holds the Guinness World Record for the world’s quietest place, but stay there too long and you may start hallucinating.
It achieves its ultra-quietness by virtue of 3.3-foot-thick fiberglass acoustic wedges, double walls of insulated steel and foot-thick concrete.The company’s founder and president, Steven Orfield, told MailOnline: ‘We challenge people to sit in the chamber in the dark – one reporter stayed in there for 45 minutes.
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.’
And this is a very disorientating experience. Mr Orfield explained that it’s so disconcerting that sitting down is a must.
He said: ‘How you orient yourself is through sounds you hear when you walk. In the anechnoic chamber, you don’t have any cues. You take away the perceptual cues that allow you to balance and manoeuvre. If you’re in there for half an hour, you have to be in a chair.’
The chamber is used by a multitude of manufacturers, which test how loud their products are.
Mr Orfield said: ‘It’s used for formal product testing, for research into the sound of different things – heart valves, the sound of the display of a cellphone, the sound of a switch on a car dashboard.’
It’s also put to use to determine sound quality.
Mr Orfield and his team will help companies such as washing-machine maker Whirlpool develop metaphors for what sound should, well, sound like.
Motorbike maker Harley-Davidson used the lab, for instance, to make their bikes quieter, while still sounding like Harley-Davidsons.
‘We record products and people listen to them based on semantic terms, like “expensive”, “low quality”, said Mr Orfield. ‘We measure their feelings and associations.’
Nasa, in the mean time, works on the identical slot provided to test it's astronauts.
There're put in place the water-filled tank in the place to find out ‘how prolonged it will take previous to hallucinations come about and also if they might work through it’.
Seeing that Mr Orfield clarifies, place is much like one big anechoic slot provided, therefore it’s critical of which astronauts will be able to remain concentrated.
Mr Orfield admits which he can easily final an extremely reputable thirty minutes within the slot provided, irrespective of possessing the off-putting kinetic center valve of which abruptly becomes quite high in volume really the moment he’s interior.
