Imagine a world where you have complete control over the sounds you hear, whether strolling through a bustling park and focusing solely on birds chirping or tuning out the din of a noisy café to concentrate on a conversation. Researchers at the University of Washington have made this a reality with their groundbreaking advancements in noise-canceling technology.
Moreover, users can effortlessly choose the sounds they wish to hear through a smartphone app or voice commands. The software then identifies and plays those sounds through the headphones in real-time, effectively filtering out all other noise. Finally, the researchers had to ensure that the extracted sounds were synchronized with the user’s visual senses. This was crucial to creating a cohesive and natural auditory experience in which the sounds heard through the headphones matched what the user was seeing.According to Gollakota, “The neural network algorithms must process sounds in real time in under a hundredth of a second.”
“We also saw interference removal improve from 1.71 to 3.05 for the target speaker compared to the raw unprocessed input.”. They also applied their AI-powered approach to human speech, developing an algorithm that can isolate a speaker’s voice from ambient noise in real time. This feature has the potential to greatly improve the clarity of conversations in noisy environments, such as crowded restaurants or busy streets.
