Ends with a space between the words equivalent to 7 "dit". Realized on a computer with a sine wave of 440 Hz. For more information on Morse: https://en.wikipedia.org/wiki/Morse_code.

Eurosignal
Characteristic beep of the Eurosignal radio paging service, operated in France, Germany, and Switzerland from 1975 to 2005. One of the first consumer paging networks in Europe, it allowed people to reach someone carrying a small portable receiver: dialing their number from a landline triggered a series of beeps alerting the bearer that someone was trying to contact them, leaving it up to them to call back from the nearest phone.
The signal was broadcast on the FM band, between 87.3 and 87.5 MHz, and could be picked up on any radio tuned to those frequencies — so much so that many listeners still remember these sequential tones bleeding through at the low end of the dial.
Made obsolete by the arrival of GSM, Eurosignal stands as a reminder of a time when mobile communication meant knowing you had to call back — without knowing who, or why.

Flash powder #1
Sound of a "Flashing powder" flash.
In the middle of the 19th century, the average exposure time in photography was around 30 seconds. In 1887, Adolf Mieetke and Johannes Gaedicke invented "Flashing Powder". It is an explosive mixture made of magnesium, potassium chlorate and antimony. Once ignited, its combustion provides a bright light, noise but also a lot of smoke. The first flash was born and made it possible to shorten exposure times.
