Comment entendons-nous?<\/h2>\n

L\u2019ou\u00efe est l\u2019un de nos cinq\u00a0sens. L\u2019audition est un processus complexe\u00a0par lequel les sons sont d\u2019abord capt\u00e9s, puis transmis \u00e0 notre cerveau, qui les interpr\u00e8te. L\u2019oreille est divis\u00e9e en trois\u00a0parties\u00a0: l\u2019oreille externe, l\u2019oreille moyenne et l\u2019oreille interne.\"\"<\/a><\/p>\n

L\u2019oreille externe est compos\u00e9e du pavillon de l\u2019oreille, du canal auditif et du tympan (membrane tympanique). Les ondes sonores sont capt\u00e9es par le pavillon, pour ensuite emprunter le conduit auditif et frapper le tympan, qui commence \u00e0 vibrer et transmet le son \u00e0 l\u2019oreille moyenne.<\/p>\n

L\u2019oreille moyenne est l\u2019espace rempli d\u2019air situ\u00e9 derri\u00e8re le tympan. Elle contient les trois\u00a0os les plus petits du corps humain, appel\u00e9s les osselets. Cette cha\u00eene d\u2019os minuscules est reli\u00e9e au tympan \u00e0 une extr\u00e9mit\u00e9 et \u00e0 la cochl\u00e9e (oreille interne) \u00e0 l\u2019autre extr\u00e9mit\u00e9. Les vibrations du tympan font vibrer les os, ce qui fait vibrer la cochl\u00e9e (oreille interne). Tout fluide ou toute pression anormale dans l\u2019espace de l\u2019oreille moyenne entrave ce processus de transmission du son entre les trois\u00a0parties de l\u2019oreille.<\/p>\n

L\u2019oreille interne est compos\u00e9e de l\u2019organe de l\u2019audition (la cochl\u00e9e) et de celui de l\u2019\u00e9quilibre (canaux semi-circulaires). Comme mentionn\u00e9 pr\u00e9c\u00e9demment, les osselets sont physiquement reli\u00e9s \u00e0 la cochl\u00e9e et font ainsi vibrer le fluide contenu dans la cochl\u00e9e. Le nerf auditif est lui aussi reli\u00e9 \u00e0 la cochl\u00e9e et est \u00ab\u00a0excit\u00e9\u00a0\u00bb par les vibrations du fluide. Le nerf auditif envoie l\u2019information sur les sons per\u00e7us au cortex auditif situ\u00e9 dans le cerveau.<\/p>\n[\/vc_column_text][vc_column_text]\n
