The sound is a very strange thing. A resbbing room can be fixed with the same foam in a corner. The noise can be ‘canceled’ by playing an upside -down wave on your ears. And now a new research has shown that you can move the sound into a room, even turning it around obstacles, so it can only be heard by someone standing in a particular place.
A team of researchers from the Penn State College of Engineering is fixing a technology that allows them to create a “audible enclave” via non -liner self -banding ultrasonic beam (Via. Future) And if all this is a gobludigo for you, allow me to explain.
Ultrasound is essentially stable with more frequency over 20 kg, which often exceeds the extent that can be heard by the average human. PAN State Team is using Two beams of ultrasound waves Working as a career for a hearing sound.
They are silent on the human ears as long as they are forced to steal, which makes a difference in frequency, say, in a 40,000 Hz and a 39,500 Hz to create a new sound wave, equivalent to the difference – in this example, 500 hazards.
Yun Jing, Professor of Sounds at Pan State College of Engineering, Explains the current procedure:
“We use two ultrasound transplants with a voice metaspace, which removes self -bending beams that meet each other at a certain place. The person standing at this point can hear the sound, while no one will stand.
“We have essentially created a virtual headset,” says Jia Zen Zhong, co -author of the study.
The effect is like throwing someone’s voice, except that instead of a strange ventiloxist dummy as a recipient, it is yours, perhaps standing in a museum, looking at a painting and leaving the other museum without listening to the artist’s biography.
However, in addition, researchers say that it is possible to use sound metastorphosis in order to bend the sound, as the optical lens turns light, which means that you can potentially break these ultrasonic waves because they travel to avoid obstacles.
Unfortunately we are probably still too far away from one Origin Virtual Headset, as the current procedure requires some large equipment directly behind your head and can only throw a sound up to three feet, which is a bit shameful.
Nevertheless, perhaps one day in the future we will be raising a voice in the rooms in which everyone is unaware of happiness.
Or, you know, we can just wear a good set of headphones. Curse, I have ruined it, are I not? Nevertheless, Coal Tech does cool tech things. Why do I say that is why you can come to a good invention.
