For the conceptual and formal development of my friendly army I looked a bit closer into the references and allusions for the receiver sculpture – i.e. into military acoustic location devices.

“Acoustic location was used from mid-WW1 to the early years of WW2 for the passive detection of aircraft by picking up the noise of the engines. Horns give both acoustic gain and directionality; the increased inter-horn spacing compared with human ears increases the observer’s ability to localise the direction of a sound.”
