Guinness World Records last week acknowledged the 58-year-old Canberra resident recorded the loudest ever shout by an individual. He yelled "now" at 122.4 decibels, the noise range of a chain saw, a jet aircraft taking off and an ambulance siren at close range.
That broke the previous record of 121.7 dB set by Northern Ireland schoolteacher Annalisa Flanagan in 1994. She had yelled an ear-piercing "quiet."
The record attempt was not something McGrail-Bateup could train for, he said Tuesday.
"There's no way that you can actually practice for it. You have to just keep it for the day, especially with the world record attempt," McGrail-Bateup said.
"It took me seven attempts just for one word, which was the word ‘now,’ and my voice was shot for the next couple of days as well. It was husky. It was terrible. So no, you can’t really practice for it. But it’s a lot of fun when you’re doing it," he added.
