Silent disco has become a common name for a disco where people dance to music listened to on wireless headphones. Rather than using a speaker system, music is broadcast via a radio transmitter with the signal being picked up by wireless headphone receivers worn by the participants. Those without the headphones hear no music, giving the effect of a room full of people dancing to nothing. Often two DJs compete for listeners. Silent discos are popular at music festivals as they allow dancing to continue past noise curfews. Similar events are “mobile clubbing” gatherings, where a group of people dance to the music on their personal music players.
