Deaflympics
The Deaflympics, also known as Deaflympiad (previously called World Games for the Deaf, and International Games for the Deaf) are a periodic series of multi-sport events sanctioned by the International Olympic Committee (IOC) at which deaf athletes compete at an elite level. Unlike the athletes in other IOC-sanctioned events (the Olympics, the Paralympics, and the Special Olympics), athletes cannot be guided by sounds (such as starting pistols, bullhorn commands or referee whistles).
