Japanese scientists believe that humans are able to locate in echo, a characteristic feature in animals such as bats and dolphins.0: 00/3: 28 South regions A new study appears on PLOS ONE Magazine In early this month, people could use the EchoLocation, or the ability to feel echo to locate, help determine the shape and movement of objects through sound. Thus people have the ability to "look" everything in the dark. Using the ability to locate in echo to "look" everything in the dark. When the bats fly around the object, they will emit High-intensity waves from different angles and bouncing back into the distance periods
. As a result, bats can identify the shape, structure or movement of an object. Sumiya Doctor, researcher at the Neurological Network and Information Center in Osaka, Japan is also one The authors of the new study, indicating that this finding can help better understand the human brain. "Human testing has the ability to feel new to identify the environment using sound (solid Separate echo) Can add a step forward in understanding the complexity of human brains
We can also better understand the feelings of other species (like bats) by comparing with collection knowledge Being in studies of human sound positioning, "said Dr. Sumiya said. Test using locative glass in echo.Con owner 5 basic senses are tactile, visual, hearing , taste and smell. According to scientists, people actually have many other subcutators such as space orientation, awareness of the body position and receiving the feeling of pain while other animals are injured, even with the senses More advanced as can detect electrical signals, words. And there is a human sense that can be proficient soon, which is the ability to locate bat species. To verify this theory, Dr. Sumiya's group has arranged a meticulous experiment. In One room, researchers give volunteers a headset and 2 tablets, one makes a positioning signal with synthetic resonation, the other to listen to the resonators that were available. In the room No
2, only the 3D axis with a strange shape stands on one place and turns around itself. When prompted, 15 participants opened the positioning signals in an echo from the tablet. The sound waves emitted by each beat, transmitted to room No. 2 and hitting the 3D axes. The experimental participant needs to have a little imagination to convert sound waves into a certain object. Dr. Sumiya explains the signal positioning in a synthetic resonator used in the experiment is high-frequency signals up to 41 kHz that people cannot hear. The researchers have used a fake head (equal to 1/7 size of the real skull) to "listen to" the sound in the room No. 2 before passing on to volunteers. The fake head is equipped with 2 microphones attached to both ears and creating sound Vang 3D. The sound emits quite similar to the surround sound like experience in cinemas. The frequency reduction of echo in both ears help participants can hear it "feel like listening to sound in real space". Many people like to listen to podcasts or watch videos with headphones to create sounds Surround bar. This is called an automatic stimulating stimulus response, or ASMR (Autonomous Sensory Meridian Response). The study participants can determine the existence of rotary cylinders only by using sound resilient. Through the sound and height of echo although it is impossible to directly look at the objects. However, they cannot accurately identify the shape of static objects with special grooves engraved on the surface. The researchers said this project is evidence that both people and bats are capable of solving Item identifiers through sound. Scientists also believe this research is very potential for practical applications for visually impaired people. In the future, visually impaired people can orient the world with echoing technology.
