Skoda DuoBell targets 750Hz-780Hz ANC gap
- Skoda developed the DuoBell, a mechanical bicycle bell designed to be heard through active noise cancellation headphones.
- Skoda said research found a frequency gap between 750Hz and 780Hz where ANC, or active noise cancellation, is less effective at suppressing external sound.
- The bell uses a dual-resonator system and an irregular striking mechanism to make the sound harder for ANC systems to block.
Skoda developed the DuoBell in April 2026 as a mechanical bicycle bell designed to be heard through active noise cancellation, or ANC, headphones. The Czech manufacturer said the design targets a 750Hz to 780Hz frequency range that its research identified as less effectively suppressed by ANC algorithms.
Skoda said the DuoBell combines a dual-resonator system with an irregular striking mechanism. According to the company, those design choices help prevent ANC systems in headphones and earphones from processing and blocking the bell sound.
The announcement reflects a wider consumer audio trend in which ANC performance in headphones and earbuds has improved, reducing the audibility of external warning sounds. The source article cites Sony headphones and Samsung Galaxy Buds products as examples of devices with strong ANC, while Skoda positions the DuoBell as a response to that change in street and cycling safety conditions.

- What is the Skoda DuoBell?
- It is a mechanical bicycle bell from Skoda designed to be heard through active noise cancellation headphones. Skoda said it targets a 750Hz to 780Hz frequency range and uses dual resonators with an irregular striking pattern.
- How does the Skoda DuoBell get through noise-canceling headphones?
- It uses a frequency range of 750Hz to 780Hz that Skoda said ANC suppresses less effectively. It also uses a dual-resonator system and an irregular striking mechanism to make the sound harder for ANC algorithms to block.
