Avez-vous d\u00e9j\u00e0 pris une minute pour \u00e9couter tous les sons \u00e9tonnants qui nous entourent ? Les feuilles qui bougent au gr\u00e9 du vent, le solo de guitare parfait de votre chanson pr\u00e9f\u00e9r\u00e9e, les enfants qui rient, un insecte qui bourdonne autour de votre t\u00eate. Nous ne prenons souvent pas le temps de r\u00e9fl\u00e9chir au nombre de sons, \u00e0 la fois simples et complexes, pr\u00e9sents dans notre vie quotidienne ou \u00e0 la pr\u00e9cision incroyable avec laquelle notre syst\u00e8me auditif absorbe instantan\u00e9ment toutes les informations et donne un sens \u00e0 ce que nous entendons. D\u00e9composons donc le processus auditif en \u00e9tapes pour mettre en \u00e9vidence \u00e0 quel point notre syst\u00e8me auditif est incroyablement complexe.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Le son, une vibration<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Tout son est une vibration de l\u2019air, une onde. C\u2019est quand la vibration se rend jusqu\u2019\u00e0 l\u2019oreille et fait le trajet jusqu\u2019au cerveau qu\u2019on l\u2019entend. \n\nEst-ce qu\u2019un arbre qui tombe dans la for\u00eat fait du bruit s\u2019il n\u2019y a personne pour l\u2019entendre\u2009? La r\u00e9ponse est oui!\n\nIl cr\u00e9e des vibrations dans l\u2019air, il fait donc du bruit. Si une oreille est pr\u00e9sente pour capter ces vibrations, alors la vibration aura un sens. Elle sera comprise par le cerveau comme \u00e9tant un son.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Revenons \u00e0 notre musique dans la voiture. Le son cr\u00e9\u00e9 par les haut-parleurs fait vibrer l\u2019air autour de nous. Cette vibration, qu\u2019on peut appeler \u00e9nergie acoustique, entre dans l\u2019oreille et se rend jusqu\u2019au tympan. Le tympan est une membrane qui agit comme la peau d\u2019un tambour. Elle transforme l\u2019\u00e9nergie acoustique en mouvement, qu\u2019on appelle \u00e9nergie m\u00e9canique.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

L'oreille moyenne : Transformer l\u2019\u00e9nergie acoustique en \u00e9nergie m\u00e9canique<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t

Le tympan est reli\u00e9 aux plus petits os du corps, les osselets. Ces 3 petits os forment une chaine qui amplifie le mouvement du tympan. Ainsi, les tr\u00e8s l\u00e9g\u00e8res vibrations de l\u2019air peuvent traverser l\u2019oreille jusqu\u2019\u00e0 la cochl\u00e9e. La cochl\u00e9e est l\u2019organe de l\u2019audition qui a la forme d\u2019un escargot. Elle est remplie de liquide et sa paroi est tapiss\u00e9e de cils. Les osselets sont attach\u00e9s \u00e0 une fine membrane \u00e0 la base de la cochl\u00e9e. Ils poussent et tirent sur la membrane au rythme de la fine vibration de l\u2019air qu\u2019ils ont amplifi\u00e9e. Ce mouvement cr\u00e9e des vagues dans le liquide de la cochl\u00e9e.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

L'oreille interne : Cr\u00e9er de l\u2019\u00e9nergie \u00e9lectrique<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t

Comme mentionn\u00e9 plus t\u00f4t, on retrouve des cils plant\u00e9s tout au long de la cochl\u00e9e. Ils servent \u00e0 transformer la vague en un message \u00e9lectrique compr\u00e9hensible pour le cerveau. Les vagues font bouger des endroits pr\u00e9cis selon le son entendu.\u00a0<\/p>\n

Les cellules cili\u00e9es sont organis\u00e9es de mani\u00e8re tr\u00e8s sp\u00e9cifique \u00e0 l\u2019int\u00e9rieur de la cochl\u00e9e, et diff\u00e9rentes cellules cili\u00e9es sont responsables de l\u2019encodage de diff\u00e9rentes fr\u00e9quences. Si vous deviez d\u00e9m\u00ealer compl\u00e8tement la cochl\u00e9e en forme d\u2019escargot, elle ressemblerait \u00e0 un piano avec des cellules cili\u00e9es \u00e0 basse fr\u00e9quence \u00e0 une extr\u00e9mit\u00e9 se d\u00e9pla\u00e7ant vers les cellules cili\u00e9es \u00e0 haute fr\u00e9quence \u00e0 l\u2019autre. Le point le long de la cochl\u00e9e o\u00f9 l\u2019onde progressive a le plus d\u2019\u00e9nergie (le \u00ab plus grand \u00bb) correspondra \u00e0 la fr\u00e9quence de la source sonore. La plupart des sons complexes que nous entendons ne sont pas constitu\u00e9s d\u2019une seule fr\u00e9quence, mais de plusieurs fr\u00e9quences toutes regroup\u00e9es. Malgr\u00e9 tout, la cochl\u00e9e est capable de d\u00e9composer ces sons complexes en simples signaux \u00e9lectriques que le cerveau traite et \u00e0 qui il attribue un sens afin que nous puissions reconna\u00eetre le son comme votre solo de guitare pr\u00e9f\u00e9r\u00e9.<\/p>\n

Ils sont un amalgame de plusieurs fr\u00e9quences ensemble. Malgr\u00e9 tout, la cochl\u00e9e est capable de d\u00e9faire ces sons en messages \u00e9lectriques simples pour que le cerveau puisse les analyser et leur donner un sens. Ainsi on peut reconnaitre le morceau de musique qui joue. L\u2019ou\u00efe est un sens fascinant auquel la majorit\u00e9 d\u2019entre nous ne portons pas grande attention jusqu\u2019\u00e0 ce qu\u2019il y ait un probl\u00e8me. Quand on d\u00e9fait le chemin du son en ses diff\u00e9rentes parties, il devient impressionnant de comprendre combien de petites portions travaillent ensemble pour nous permettre d\u2019appr\u00e9hender le mode sonore autour de nous. Pour en apprendre plus sur les diff\u00e9rentes parties du syst\u00e8me auditif pouvant faire d\u00e9faut et entrainer des pertes auditives,\u00a0cliquer ici<\/a><\/span>.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
