Si vous jetez une pierre dans l’eau, les ondes s’\u00e9tendent en cercle. De la m\u00eame mani\u00e8re, une source sonore cr\u00e9e des changements de pression dans l’air. Ces changements rapides de la pression atmosph\u00e9rique sont per\u00e7us par l’oreille comme un son.<\/p>

Les ondes sonores sont des fluctuations de la pression atmosph\u00e9rique caus\u00e9es par des \u00e9v\u00e9nements sonores. La longueur des ondes sonores d\u00e9finit la fr\u00e9quence, la hauteur des ondes sonores le niveau. Les ondes sonores longues ont une fr\u00e9quence basse et sont per\u00e7ues comme des tons profonds. Les ondes sonores courtes ont une fr\u00e9quence \u00e9lev\u00e9e et sont per\u00e7ues comme des sons aigus.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
