Somehow, even in a room full of loud conversations, our brains can focus on a sound in something called a cocktail party effect. But the taller it is – or the bigger you are – the harder it is to do. Now, researchers have figured out how to solve it with a machine learning technique called calming suspicion.
Computer scientists trained a brain network, which almost mimics brain wires, to detect and distinguish the sounds of many people speaking in a room. The network partially measured how long it took for the sounds to hit the cluster of microphones in the center of the room.
When researchers examined their setup with very loud background noise, they found that the angle of silence is located between two sounds. Within 3.7º of their source, He reported at an online-only conference of neural information processing systems this month. That compares with the previous state’s sensitivity of only 11.5º for modern technology. When researchers trained their new system on additional sounds, it performed the same trick with eight sounds – a sensitivity of 6.3º – although it did not hear more than four at a time.
Such a system can one day be used in hearing aids, monitoring setups, speakerphones, or laptops. New technology, whatever it may be Track moving sounds, Maybe simplify your zoom calls, isolate and The background is turning off the noise, From vacuum cleaners to off-season children.
