  "textContent": "If you ride in urban environments at all – even if just to get out of town – you're undoubtedly familiar with startling pedestrians on multi-use paths even after you rang a bell to alert them of your pass. The problem isn't your bell: it's that many people now wear some kind of noise-canceling headphones that supress the sound of the bell.\n\nAutomaker Škoda has come up with an innovative solution: a bell technology that uses a sound frequency that noise-canceling headphones don't filter, and a two-tone ring that further cuts through the tech. Crucially, it does this entirely with analog technology; there are no electronics involved to charge (or eventually fail).\n\nA mockup of Škoda's Duobell, with the dual-frequency and variable striker mechanism.\n\nŠkoda worked with researchers at the University of Salford to identify a frequency band between 750-780 Hz that noise-canceling tech is bad at filtering. So the bell operates primarily at that frequency, while a second tone (the \"duo\" part) emits sound at a higher frequency as a specially designed striker mechanism generates variable sound waves that noise cancelation algorithms have trouble filtering.\n\nŠkoda claims that in testing with delivery riders in London, the tech offered up to five seconds more alert and reaction time with headphone users than conventional bells. The catch: you can't buy it yet. Instead of manufacturing the bell, Škoda is offering the technology for free so that other brands can use it. [Škoda]",
