2014 World Cup noisemakers quieter than vuvuzelas

Researchers say the official noisemakers for next year’s World

Cup soccer tournament in Brazil will be significantly quieter than

the vuvuzela (voo-voo-ZEHL’-uh) horns that caused so many headaches

in 2010.

The new instrument is a rattle called the caxirola

(ka-SHE’-rah-luh), and it creates sound pressure levels similar to

normal conversation.

Researchers from the Federal University of Santa Maria in Brazil

said Thursday that it would take about 2,000 caxirolas to emit the

same noise level as one vuvuzela.

In South Africa, throngs of fans playing vuvuzelas created a

deafening roar during matches.

The incessant buzzing from the long, skinny horns was so loud

that players on the field had a hard time communicating, and many

TV viewers initially thought there were reception problems.
