Annalisa Flanagan uses her impressive shout on her P4 pupils in Finaghy Primary School

Teacher Annalisa Flanagan from Comber has something to shout about after her sensational voice was re-entered into the Guinness Book of Records as the loudest in the world.

It's been well over a decade since Annalisa’s shout of 121 |decibels — the equivalent of a jet engine — and her achievement is still a world record.

The new edition of the book, which includes the world's |smallest cow, heaviest gooseberry and largest collection of Smurf memorabilia, records the world's loudest shout, registered in Belfast in 1994.

In 1992 Annalisa, accompanied by her twin sister, first started her noisy quest when both |competed in a local ‘records night' where various Guinness entries were challenged.

The twins both managed to clock in above 119 decibels, with Annalisa just having the upper hand, or should we say larynx.

She joked: “We should have pushed it further, we could have been the world's loudest twins.”

With such a clear talent for shouting, Annalisa decided to enter a Citybus shouting contest two years later to flaunt her skills. It was here that she broke the world record, reaching an impressive 121.7 dBA — a noise to rival a jet engine or a rock concert. Ironically, she shouted the word ‘quiet' to gain her record.

Describing her record as “crazy”, she said “people train for years but I was just in the right place at the right time”.

Since having her tonsils removed a few years ago, Annalisa fears she may have lost her record-breaking touch. These days she generally keeps her shouting to the hockey pitch where she says her still-impressive voice comes in handy.

Annalisa, a primary school teacher in Finaghy, south Belfast, says she doesn't often have to shout in the classroom — but with a such a strong voice her pupils would probably rather not tempt fate.
