Sven Wipperfurth was in the crowd at Germany's 4-0 victory over Australia but failed to enjoy the match when a fan next to him start blowing his vuvuzela when Lukas Podolski gave Germany the lead.
"It was so loud that I winced," Wipperfurth told German paper Bild, and for the rest of the match he had a ringing sound in his ear.
After the game he visited a doctor who told him that he had tinnitus, the symptoms of which are hearing loss and a prolonged ringing sound in the ears.
He was ordered to take time off work and was prescribed Tebonin - a drug usually given to those with dementia for its ability to increase blood-flow to the brain.
Vuvuzelas can generate a drone of up to 144 decibels inside stadiums, which is louder than fireworks, a plane taking off or a rock concert.
Wipperfurth made his opinion about the instrument perfectly clear when he told Bild: "These devil's trumpets must be banned!"
