The first 50 visitors were given race numbers at the entrance and divided into small training groups. These involuntary jump aspirants were instructed in the art of ski jumping during the entire event at several stations supervised by “trainers” (e.g. warm-up in the finish area, joint ascent with the actual jumper in the funicular, jump training at the jump tower above the inrun, etc.). Some of these visitors briefly had the impression that they were actually expected to jump over the 90m ski jump. Since groups of people with start numbers were constantly moving across the entire area in an athletic manner, the remaining visitors (without start numbers) had the impression that many people were seriously planning to attempt a sound jump.

… here the details for the technical implementation

Sound ski: The jump skis are equipped with several glued sensors that react differently. A 3D Gforce sensor with a load capacity of up to 5-G is mounted behind the shovel at the tip of the ski, which reacts to movement in 3 axes and detects acceleration. Two flexion bending sensors (10 cm bi-metal strips) at the front and rear and end of the ski – where there is the most bending (take-off, flight, landing). A Shock Pieco Sensor (pressure sensitive) is located under the jump shoe, which reacts in the run-up track, during take-off and landing. Another shock sensor is mounted in the front area of the ski.

Ski jumper: The jumper also wears a knee stump, which has a flexion bending sensor and a 3D Gforce sensor sewn into it. This converts the difference between approach squat and flight, as well as the quality of the flight (shaking or steady) into data.

Transmitting system: Via thin cables, which run safely and aerodynamically along the surface of the skis, the electronic impulses are sent to the Ebody 2 HF radio transmitting system, a small box measuring 10 x 6 x 2 cm. This broadcast box is worn with a belt under the jumper’s suit. The pulses (low-frequency waves of 2.4 Ghz) are detected by a receiver connected to the computer in the target room and converted into different sound tracks via a midi and sound program.

(Yes. Some think the Pirker is a little crazy).
