Fizzy drinks, cold water and a perpetually stocked beer fridge — these are just a few trade secrets from a Darwin man who has unofficially broken a world record for the loudest burp.

Humpty Doo man Neville Sharp decided to challenge a Guinness World Record for the loudest burp after being egged on by his mates at the local pub.

The record has been held by UK man Paul Dunn for a burp of 109.9 decibels.

Mr Sharp underwent a strict training regime before belching into a decibel reader at Charles Darwin University's sound room yesterday.

"It would've been a 600ml Coke and some cool water," Mr Sharp told 105.7 ABC Darwin.

"And my beer fridge is always full."

Mr Sharp had one relatively extended yet audibly unsuccessful attempt of 97.8 decibels before a hearty and robust belch registered 110.6 decibels.

The proud burper told local Darwin media that he learnt how to belch as a child after his sister taught him to gulp air, and that breaking the record had "always been" a bit of a personal goal.

Mr Sharp will have to formally apply to Guinness World Records to claim the title, however in the eyes of both his wife and the Australian media, he is already a bit of a star.

"The phone hasn't stopped all morning. A Melbourne radio station is playing my burps," Mr Sharp said.

"My wife actually woke me up at 5:30 this morning saying 'you're on telly'. It's gone off its head."

Mr Sharp said he wished he could make money from his talent but, unfortunately, burping more loudly than a hand drill was not a particularly lucrative business.

"It would be very handy but I think it'll be my five minutes of fame and then everybody will forget about it," he said.

And what does his wife think of his training sessions at home?

"She loves me," he added.
