Kupfer-Hörner (Copper-Horns)

„During a night walk
along the canal, when everything is acoustically more intense in the darkness, I heard an
impressive exchange between a ship’s horn and the horn of a distant freight train."

Technical Details
Year:
2010
A horn group consists of 64 horns, small, modified ship’s horns. 32 horns have copper
bells whose sound color is reminiscent of trumpets. Each wind machine is powered
by a portable air compressor of the type used in road construction with a minimum pressure
of 7 bar or 100 psi (pounds per square inch) and an air flow capacity of 1.000 to 2000 CFM
(cubic feet per minute), These units have an operating dBA as low as 64 db which significantly
reduces the incidence of unwanted noise. The ship’s horns are tuned diatonically and are
controlled by a computer.
