K. Sound in Lightwaves

‘Are we on the same frequency?’

Along the Stationsweg, hanging between two trees is a Sorama sound camera. This camera registers the sounds that people make on the spot. The location, volume and frequencies from the sound field - the longitudinal sound waves from all directions – are analysed and transformed into digital information. This local information about the pitch of the sounds is transformed into a pattern of coloured light on the TU/e campus chimney.

The light waves move transversally and are transmitted by the ‘AnTUenna’, creating a picture of the street sounds. The content of the sound close to the sound camera is depicted at the top of the chimney and at the bottom of this light beacon the sonic image is visible from the more distant sounds detected by the sound camera. Looking at the chimney almost 700 metres away, the sounds to the right and left of the camera are visualised on the right and left of the chimney.
Sound waves move a lot less quickly than light waves. The time that is required to register the sound is in the order of several hundredths of a second. The time between detection of the sound and observation of the moving light patterns is just a couple of millionths of a second. This interactive sound and light installation creates a sensation as though the sound effects simultaneously cause a single moving light image in different colours.
