Football fans attending the World Cup are being warned they risk permanent hearing damage from the vuvuzela horns which are the must-have accessory at the South African tournament.
Hearing aid manufacturer Phonak says the din emitting from the tuneless plastic horns is louder than a chainsaw.
It says tests have shown the sound emitted by a vuvuzela is equivalent to 127 decibels.
The company says extended exposure to just 85 decibels puts people at risk of permanent noise induced hearing loss.
