DAEJEON, June 18 (Korea Bizwire) — A newly introduced technology can locate the source of sound more precisely and quickly, raising hopes that it might be used to find survivors in the mountains or in other emergency situations.
A joint research team from the Korea Research Institute of Standards and Science and Pohang University of Science and Technology (POSTECH) said Thursday that they it had developed technology that can visualize the source and volume of a sound using artificial intelligence (AI).
Previous technologies, used widely in the fields of reconnaissance, transport, and rescue, have been lacking in separation of sounds or accuracy.
As such, they couldn’t go as far to estimate the sound’s volume. Also, locating the sound source became even more difficult in noisy environments.
The team’s AI-based sound tracking technology can locate the sound source in just one-tenth of the time needed for previous technologies, and is capable of offering 10 times more accurate information, even in poor conditions with high background noise.
This technology can be used to locate the source of leaks, whether it be electricity, gas, or water, as well as locating the source of noise between apartment floors.
The research team’s study was published in last month’s edition of Mechanical Systems and Signal Processing.
