Le syst\u00e8me auditif est tr\u00e8s complexe. Cependant, si on le simplifie, il peut \u00eatre divis\u00e9 en trois parties\u00a0principales\u00a0: l\u2019oreille externe, l\u2019oreille moyenne et l\u2019oreille interne. Dans chaque section, il existe des structures qui jouent un r\u00f4le important dans le processus qui nous permet d\u2019entendre dans nos environnements quotidiens.<\/p>\n

Oreille externe<\/strong><\/h3>\n

L\u2019oreille externe est comprise de la pinna (le pavillon), le canal auditif et le tympan. La pinna est la partie visible de l\u2019oreille. Elle est responsable de diriger le son directement dans le canal auditif. Quand le son rejoint le bout du canal auditif, il frappe le tympan et le fait vibrer. Ceci transfert le son \u00e0 la prochaine \u00e9tape: l\u2019oreille moyenne.<\/p>\n

Oreille moyenne<\/strong><\/h3>\n

L\u2019oreille moyenne est une cavit\u00e9 remplie d\u2019air qui est maintenue \u00e0 une pression \u00e9gale avec celle de l\u2019ext\u00e9rieure par l\u2019entremise de la trombe d\u2019Eustache, qui relie l\u2019oreille \u00e0 la partie arri\u00e8re du nez. On retrouve aussi dans l\u2019oreille moyenne trois petits osselets (le marteau, l\u2019enclume et l\u2019\u00e9trier), qui vibrent avec le mouvement du tympan, et continuent de transf\u00e9rer le signal sonore vers l\u2019oreille interne.<\/p>\n

Oreille interne<\/strong><\/h3>\n

L\u2019oreille interne est l\u2019endroit o\u00f9 les ondes sonores se font analys\u00e9es pour la premi\u00e8re fois. On y retrouve des petits cils (cellules cili\u00e9es), plus sp\u00e9cifiquement dans la cochl\u00e9e, qui sont activ\u00e9es par des sons pr\u00e9cis. Ces petits cils transmettent le son au cerveau par l\u2019entremise du nerf auditif, apr\u00e8s quoi le cerveau interpr\u00e8te le signal sonore.<\/p>\n

Trois \u00e9tapes vers une meilleure audition<\/strong><\/h3>\n
