What is Silence Disco
According to Wikipedia, silent disco or silent rave is an event 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.
The advantage of this new trend is that it is no restriction by the place and does not affect the neighborhood.
Another type of silent party, known as mobile clubbing, involves the gathering of a group of people in an unconventional location to dance to music which they provide themselves via a portable music device, such as an MP3 player, listened to on headphones. These flash mob gatherings may involve hundreds of people, transforming public spaces into temporary clubbing areas, in which dancers listen to their personal playlists. To an observer it would appear that the participants are dancing for no apparent reason. Mobile clubbing events are organized using mass-emails, word-of-mouth or social networking websites such as Facebook, or a combination of these methods.
