Most people would struggle to imagine a human voice being loud enough to rival the roar of a jet engine, but that is exactly what Australian town crier Joseph McGrail-Bateup has achieved. The 58-year-old from Canberra recently set the Guinness World Record for the loudest shout by a male after reaching an astonishing 122.4 decibels, a sound level comparable to a jet aircraft taking off at close range. According to Guinness World Records and the Associated Press, his record-breaking shout surpassed a mark that had stood for more than three decades and demonstrated just how powerful the human voice can be.
