According to hearing experts and doctors, the World Cup sound pest known as the vuvuzela is a health risk. The long, colorful plastic horns emit a buzzing noise at 127 decibels, loud enough to cause permanent hearing damage to spectators. Researches have found that air particles from the horn stay suspended in the air for hours. Thus, the horn could potentially spread illnesses rapidly if blown by someone with a airborne illness (common cold, chicken pox, rubella, SARS, H1N1) in a crowded stadium. Some experts, such as doctors at South Africa's National Institute for Communicable Diseases do not feel the risk is any different from shouting or sneezing.
