Résumé

The Youtube channel Zeste de science explores all aspects of scientific research, proving that even the most complicated scientific facts can be explained in less than 5 minutes, and that even the most seemingly trivial events of everyday life, if thoroughly studied, can contribute to the biggest technological advances.
Episode 18: Zeste de science presents the first episode of Ecorce de recherche, an immersion into archives of last century's scientific research. Every concert hall needs the best possible acoustic quality. But to assure acoustic quality in an enclosed space, you first need to see how sound is distributed in said space. With that goal in mind, scientists built two devices in 1951: a water tank in which water ripples represent sound waves, and an ultrasound system.
