A viral trend among Kenyan football fans involves using a dedicated mobile app, Mwananchi Noise, to collectively measure the decibel level of cheers during home matches. The app aggregates data from hundreds of phones in the stadium to create a real-time roar meter shown on social media. Fans of Kakamega Homeboyz currently hold the record at 114 decibels. It’s a fun, tech-driven way to quantify our 12th man and see which stadium has the loudest supporters, said a fan from the Bukhungu legion.
