DuoBell

AI Overview

Škoda redesigned the bicycle bell by identifying the acoustic frequency range that noise-cancelling headphones cannot block, creating a patented mechanical solution that gives pedestrians 5 extra seconds to react. The company then released the research openly, turning a product into a global urban safety standard.

Strategic insight

The insight came from data, not intuition. By analyzing which frequencies ANC algorithms fail to suppress, Škoda reframed a century-old problem as a physics problem, solvable through acoustic precision rather than digital complexity.

Earned Reach

Within 48 hours, coverage extended far beyond automotive press to technology and design publications including The Verge, Fast Company, Dezeen, and Wired Italia. Collaborators Hannah Fry and London Hustle amplified the story to millions on social, generating €2.6M in media value on a €260K budget.

Cultural Impact

Partnerships with Deliveroo, Forest Bikes, and Transport for London signal the work has transcended campaign status. The open whitepaper and patented design are establishing DuoBell as an emerging urban safety standard rather than a one-off product.
