Researchers at Nanyang Technological University in Singapore have developed a prototype device that reduces incoming noise by 10 decibels. This technology utilizes 24 small speakers within a window frame to emit sound waves that neutralize incoming noise.
The device's technology draws inspiration from noise-canceling headphones but expands the concept to an entire room. The motivation behind this research stemmed from the high level of noise pollution in Singapore, as highlighted by Dr. Lam, a researcher involved in the project.
The study's results were published in Scientific Reports. While the prototype requires further development for real-world applications, it presents a promising path toward creating noise reduction technology that could alleviate the problems of city noise.
