People often say that "silence is gold", but there is a room in the United States that is very quiet, and almost no one can stay there for a while. The longest time to stay in the "anechoic chamber" of Orfield Laboratories in South Minneapolis is only 45 minutes. 99.99% of the sound is absorbed here. It is the quietest place on the planet determined by the Guinness Book of World Records. Staying here for too long may make you hallucinate.
This anechoic chamber achieves this super quiet effect with a 3.3 ft (1.01 m) fiberglass sound absorbing tip, double insulated steel walls and 1 ft (30.48 cm) of concrete. The company's founder and president, Steven O'Fairfield, said: "We invite people to sit in this dark anechoic room, where a reporter stays for 45 minutes. When the surroundings are in a silence, the ears will be very fast. Adapt to the surrounding environment. The quieter the room, the more you hear. You will hear your heartbeat, sometimes you can even hear the sound of the lungs and hear the snoring in your stomach. You have become a source of sound." He said that this is a confusing experience, and it must be quietly sitting to be able to spend, which is terrifying.
He said: "How do you adapt yourself to the sound of walking? You don't have any hints in the anechoic room. Here, all the cues that can help you balance and self-regulate disappear. If you want to Staying there for half an hour, you have to sit quietly in the chair.†All American companies are using anechoic chambers, including NASA, which uses the anechoic chamber to test astronauts and let them float in a full In the water container, take a look at "How long will they have hallucinations and whether they can continue to work in this environment." As Orffield explained, space is like a huge anechoic chamber, so it is important that astronauts stay focused there.
Many manufacturers also use anechoic chambers to detect the noise of their products. Orfield said: "The anechoic chamber is used in normal product testing to study the sounds emitted by different things, such as heart valves, the sound of mobile phones, and the sound of car dashboards. In addition, some people use it. Determine the quality of the sound." Aofield and its research team will help the washing machine manufacturer, such as Whirlpool, to conduct research and see what the sound sounds like. For example, motorcycle manufacturer Harley Davidson used the lab to reduce the noise of vehicles, but still let them hear Harley Davidson's products.
Orfield said: "We record the product situation, people listen to them according to the semantic words 'expensive' and 'low quality.' We study their feelings and associations." He admitted that he can only stay in the anechoic room 30 Minutes, but when he was inside, one of his artificial heart valves suddenly became very noisy.
The "Anechoic Chamber" of the Orfield Laboratory was confirmed to be the quietest place in the world in 2004, and it still maintains this record.
