New Bike Bell Available to Alert Wearers of Noise-cancellation Hearing Devices

• Skoda has developed the DuoBell, a mechanical bicycle bell designed specifically to be heard through noise canceling headphones.
• Research identified a frequency “gap” between 750Hz and 780Hz where ANC algorithms are least effective at suppressing external noise.
• The bell also uses a dual-resonator system and an irregular striking mechanism, helping prevent ANC algorithms from processing and blocking the sound.
