· 2 sourcesŠkoda, in collaboration with the University of Salford, has developed the Duobell, a bicycle bell designed to be heard through noise-cancelling headphones. Dezeen reported that the bell operates at 750 hertz, a frequency that bypasses the audio filters commonly found in active noise-cancelling headphones. Hacker News noted that Škoda plans to make the underlying research publicly available to support broader discussion on urban safety. The innovation addresses a growing safety concern where pedestrians wearing such headphones cannot hear approaching cyclists, leading to increased collisions.
The bagel they save for the regulars. Don't skim, savour.
Summary
Czech automaker Škoda has developed the Duobell, a mechanical bicycle bell designed to be heard through noise-cancelling headphones. The bell operates at 750 hertz, a frequency that corresponds to a gap commonly found in the audio filters of active noise-cancelling headphones. This innovation addresses a growing safety concern where pedestrians wearing noise-cancelling headphones cannot hear approaching cyclists, which has led to increased bike-pedestrian collisions. The Duobell represents a practical safety solution that bridges automotive engineering with urban mobility challenges.
Key quotes
· 3 pulledCzech automaker Škoda has created the Duobell bicycle bell, which penetrates noise-cancelling headphones in a bid to tackle a growing cause of bike-pedestrian collisions.
Škoda Auto's bell is a simple, mechanical device that rings at a precise frequency of 750 hertz.
This corresponds with a narrow gap that the company found commonly exists in the audio filters of headphones with active noise cancellation.
