The Glastonbury Festival will be a much quieter place this year, with revellers partying listening to headphones, organisers said.
In a bid to keep within strict noise-limits, festival-goers wishing to party through the night in the dance tent will be given special "silent disco" headsets.
Thousands of clubbers will dance to world-famous DJs at the Somerset event, but all the neighbours will hear is the sound of shuffling feet.
The system is designed so that the music can carry on late into the night without infringing on the restrictions imposed by the festival's licence. Festival organiser Michael Eavis said the solution to the problem was his daughter's idea.
Mr Eavis said: "We have been toying with this idea for years, trying to think of ways to combat the noise limits.
"Now Emily has finally got something together so the party can go on later into the evening without infringing the noise curfew. It's a first for us, and I will be interested to see how it works."
Visitors to the dance tent will be given a complimentary set of headphones complete with bass, volume and treble controls so they can have the music as loud as they like.
After the noise curfew comes into force, the music will stop being pumped out of the 15ft speaker stacks and will instead be transmitted directly to the headsets.
The system has been developed by Dutch- firm 433fm.com, which pioneered the "silent disco" at illegal parties as part of a travelling festival in Holland.
