A silent disco is a disco where people dance to music listened to on headphones. Rather using than a speaker system, music is broadcast via an FM transmitter with the signal being picked up by wireless headphone receivers worn by the partygoers. 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 and silent gigs 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 meet up, often on short notice, to dance to the music on their personal music players.
