salle d\u2019exp\u00e9rimentation acoustique sp\u00e9ciale dont les surfaces sont con\u00e7ues de mani\u00e8re \u00e0 ce que presque aucun son n&#8217;y soit r\u00e9fl\u00e9chi.<\/p><p>La minimisation de la r\u00e9flexion du son sur les murs et le plafond est obtenue en recouvrant la pi\u00e8ce d&#8217;un mat\u00e9riau absorbant, g\u00e9n\u00e9ralement de la laine de verre ou de la laine min\u00e9rale. Avec ces mat\u00e9riaux, l&#8217;\u00e9nergie du son incident est convertie en \u00e9nergie thermique. L&#8217;\u00e9nergie ne peut \u00eatre extraite que par la friction de l&#8217;air en mouvement, cela signifie que la vitesse du son doit \u00eatre sup\u00e9rieure \u00e0 z\u00e9ro. Selon la fr\u00e9quence, elle est maximale \u00e0 une certaine distance du mur de b\u00e9ton de la pi\u00e8ce. Un mat\u00e9riau poreux doit alors \u00eatre pr\u00e9sent \u00e0 cet endroit pour amortir de fa\u00e7on optimale la fr\u00e9quence correspondante. Afin d&#8217;obtenir l&#8217;absorption sonore la plus compl\u00e8te possible, l&#8217;imp\u00e9dance sonore doit correspondre \u00e0 celle de l&#8217;air dans la gamme de fr\u00e9quences la plus large possible. Pour ce faire, la doublure est fabriqu\u00e9e \u00e0 partir de cales individuelles de mat\u00e9riau absorbant.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element
