C'est pas sorcier - Season 1 Episode 359 Les coulisses d'un concert : faites parler les décibels !
Qu'est-ce qu'un son ? Comment se propage-t-il dans l'air ? Comment un microphone le transforme-t-il en courant électrique ? Et comment amplificateur et enceintes lui donnent-ils de la puissance ? Sachant que plus l'on s'éloigne d'une enceinte, plus on perd en intensité… comment le public peut-il profiter de la même qualité sonore, qu'il soit devant la scène ou tout au fond de la salle ? D'où viennent ces affreux larsens qui vrillent parfois les tympans ? Fred et Jamy sont aux Eurockéennes de Belfort. Dans l'ambiance surchauffée de cet événement musical, ils suivent le savant travail de sonorisation indispensable à la réussite d'un concert.
