NTU Researchers Develop Noise-Canceling Device for Windows

You’ve just started your day in the office, and the next thing you know is relentless honking and noises from the construction site disrupting your concentration. The best solution you have is a set of noise-canceling headphones/earbuds which help you get back in the zone. But, what if the noise is canceled, as soon as it hits your window?

Noise-cancelling technology has already been used widely in headphones, helmets, and anti-snoring devices. Now, the researchers at Nanyang Technological University (NTU) want to embed that very technology in commercially available windows. They have come up with a prototype of a noise-canceling window device that does away with all annoying sounds from outside.

The small device can be mounted on any window to reduce agitating noises by almost 50%. The trick is a sound-emitting mechanism that generates anti-noise soundwaves to counter real-world noise, reducing it to ear-pleasing ambient sound.

The current prototype has a microphone, speaker, and a processing unit that combined detect the noise and then process the data to emit sound waves. The processing of sound is done so fast that the agitating noise gets canceled even before it reaches the ears of someone sitting in the room.

Professor Gan Woon Seng, Director of the Centre for Infocomm Technology who is leading this research said this technology effectively calculates the anti-noise faster than it can reach the premises.

The current prototype has around 24 devices mounted on the window grille to control the noise in a large area with absolute efficiency. The next phase involves reducing the number of devices required to achieve the same efficiency. Also, the team wants to do it with the windows open.

Another challenge is to effectively identify annoying noises from construction work, trains, or vehicles to the chirping of birds. For that, the developers have machine learning in place which obviously will improve with time.

Professor Gan said that they are already in the second phase of trials, and pretty soon it will be deployed in the real environment. The goal is to take this technology to residential as well as commercial locations.

    Is this product available to the general public yet? A construction crew has started working outside my condo and I would absolutely love to purchase and install this product.
    Thank you

      Christopher, this is just a working prototype, not a commercially available product. We hope that this product sees the light of day soon.
