Škoda DuoBell: a bicycle bell that penetrates noise-cancelling headphones

Škoda announced the DuoBell, a bicycle bell engineered to be heard through active noise-cancelling headphones.

ANC can reduce the audibility of conventional bells, prompting a need for louder or differently tuned alerts.

Cyclists and pedestrians often share paths, creating scenarios where audible alerts are used to avoid collisions.

Some cyclists disable ANC because it can cancel wind noise, and public spaces already face widespread noise pollution.
