The caxirola was certified on September 27, 2012 by the Brazilian Ministry of Sports and was created to be the official musical instrument of the 2014 FIFA World Cup in Brazil.
[3][4] Carlinhos Brown has expressed concern about the potential unpleasing sound of the official instrument of the Cup, as it happened with the vuvuzelas of the previous tournament.
"[5] "Researchers at Brazil's Federal University of Santa Maria determined .. that it would take 30,000 caxirolas to produce the same sound pressure level as a single vuvuzela.
