Inside the facilities at CERN, near Geneva
This is an amalgamation of recordings made entirely within the facilities of CERN on the Franco-Swiss border near Geneva.
Alongside a standard field recorder I also took a contact mic - the 'knocks' you hear are via the contact mic on various pieces of equipment that are on public display. These include sounds recorded from a particle accelerator pipe and various other bits of hardware from CERN's past including bubble chambers, an Electron / Positron Collider radio frequency cavity and a voltage doubler.
We were lucky enough to visit CERN's antimatter factory where, with the standard recorder, I captured the sound of the various machines busy making antiparticles.
Further audio was recorded within the Universe of Particles exhibition at The Globe of Science and Innovation - this is where the fragments of music and speech were captured.
