Selectively cut out some external noise so you only hear the sounds you want

The prototype noise-canceling headphones let you choose which ambient noises to drown out, allowing you to focus on specific sounds by putting an “audio spotlight” on them.
Traditional noise-canceling headphones reduce unwanted sounds such as bus engine sounds, but this technology completely cancels out certain frequencies, so you can also suppress the sounds you want to hear.
now, Shyam Golakota Researchers at the University of Washington in Seattle have developed headphones that filter out unwanted noise, regardless of frequency, while leaving other noises alone. You can also train it to focus on a specific person's voice and filter out all other noise with the push of a button.
Researchers are presenting their prototype at an exhibition. This week's joint meeting of the Acoustical Society of America and the Acoustical Soc…
The prototype consists of commercially available headphones with a microphone attached to the outside of the housing that covers each ear. These microphones record ambient sound and pass it to one of the smaller microphones. Orange Pi Microcontroller Or a smartphone running a neural network. This AI removes unnecessary sounds and sends the edited audio feed to your headphones. Gollakota says the device could be integrated into a set of headphones.
The technology works similarly to the AI ​​used to separate individual instruments and voices among the raucous noise recorded while working on the Beatles' 1970 album. let it bedirector Peter Jackson is now available to produce a documentary series the beatles: get back.
Although this process was time-consuming, the prototype can process audio within just 8 milliseconds. – That's because the team kept the neural network small and simple enough for mobile devices to run quickly. – To avoid co…
Gollakota says the effect is like an “audio spotlight” on the source of the noise, allowing you to focus on it even in chaotic, noisy environments.
“It comes with new features that give the user more control. We are now taking the first steps in augmenting human acoustic perception,” says Gollakota.
