The Takeaway

Standard noise cancellation is all-or-nothing, often leaving users feeling isolated or unaware of their surroundings. This system allows a user to target a specific bothersome sound—like a neighbor's lawnmower—and erase it in real-time while still being able to hear a conversation or an approaching car.

From the abstract

For people with noise sensitivity, everyday soundscapes can be overwhelming. Existing tools such as active noise cancellation reduce discomfort by suppressing the entire acoustic environment, often at the cost of awareness of surrounding people and events. We present Sona, an interactive mobile system for real-time soundscape mediation that selectively attenuates bothersome sounds while preserving desired audio. Sona is built on a target-conditioned neural pipeline that supports simultaneous att
