Guinness recognizes 122.4-decibel shout as world's loudest

Guinness World Records has recognized Joseph McGrail-Bateup of Canberra for a shout measured at 122.4 decibels. He produced a shout measured at 122.4 decibels on May 2 in a Canberra radio studio. A professional acoustic engineer recorded the yell with witnesses present, and Guinness World Records announced the recognition on June 19.

McGrail-Bateup holds the honorary position of town crier of Canberra, appointed in 2017 under the name Lord Joseph. He won a 2024 guild competition with a town-crier shout measured at 98 decibels. "I'm pleased that [Flanagan] gets to keep her record.

So she's still the loudest woman in the world and I'm the loudest male in the world," McGrail-Bateup said. He added that the attempt required seven tries and left his voice affected for several days afterward. McGrail-Bateup also holds an archery speed record set in 2019, when he shot 10 arrows in 60.03 seconds.
