DuoBell

Noise-cancelling headphones have quietly made the bike bell useless. The sound gets filtered out before anyone ever hears it. Working with acoustic scientists at the University of Salford and Škoda's design team, we reinvented a hundred-year-old object for the noise-cancelling age. DuoBell is the world’s first fully mechanical bell tuned to a narrow frequency that slips straight through ANC. No batteries, no electronics. An analogue solution to a digital problem.
