A z \u010deho se na\u0161e ucho vlastn\u011b skl\u00e1d\u00e1? Ucho m\u016f\u017eeme rozd\u011blit na vn\u011bj\u0161\u00ed, st\u0159edn\u00ed a vnit\u0159n\u00ed. Vn\u011bj\u0161\u00ed ucho je to, co vid\u00edme, u\u0161n\u00ed boltec a zvukovod. Tato \u010d\u00e1st kon\u010d\u00ed u\u0161n\u00edm bub\u00ednkem. To je tenk\u00e1 blanka mezi vn\u011bj\u0161\u00edm a st\u0159edn\u00edm uchem. St\u0159edn\u00ed ucho je pak speci\u00e1ln\u011b utvo\u0159eno, tak aby dok\u00e1zalo p\u0159ev\u00e1d\u011bt zvuk ze zevn\u00edho prost\u0159ed\u00ed do vnit\u0159n\u00edho ucha. Zde se nach\u00e1z\u00ed u\u0161n\u00ed k\u016fstky, nejmen\u0161\u00ed k\u016fstky v na\u0161em t\u011ble. \u0158\u00edk\u00e1 se jim klad\u00edvko, t\u0159m\u00ednek a kovadlinka. Ty jsou schopn\u00e9 p\u0159ev\u00e1d\u011bt a zesilovat zvuk (co\u017e je mechanick\u00e9 vln\u011bn\u00ed vzduchu) na ov\u00e1ln\u00e9 ok\u00e9nko. Ov\u00e1ln\u00e9 ok\u00e9nko je, podobn\u011b jako bub\u00ednek, p\u0159echod mezi st\u0159edn\u00edm a vnit\u0159n\u00edm uchem. Ve vnit\u0159n\u00edm uchu je pak org\u00e1n, kter\u00fd je schopen p\u0159ev\u00e1d\u011bt toto vln\u011bn\u00ed na nervov\u00fd vzruch, kter\u00fd jak v mozku detekov\u00e1n jako zvuk. Ve vnit\u0159n\u00edm uchu je ulo\u017een hlem\u00fd\u017e\u010f. Ten je tvo\u0159en kost\u011bn\u00fdm obalem (ten je sou\u010d\u00e1st\u00ed lebky) a uvnit\u0159 n\u011bj blanit\u00fdm hlem\u00fd\u017ed\u011bm. V tomto blanit\u00e9m hlem\u00fd\u017edi je vytvo\u0159en speci\u00e1ln\u00ed tzv. Cortiho org\u00e1n. Ten se skl\u00e1d\u00e1 s drobn\u00fdch vl\u00e1skov\u00fdch bun\u011bk, po kter\u00fdch se pohybuje membr\u00e1nka. Podle toho, jak se tato membr\u00e1na pohybuje, jsme schopni ur\u010dovat r\u016fzn\u00e9 zvuky. Jen\u017ee, tyto vl\u00e1skov\u00e9 bu\u0148ky se mohou po\u0161kodit, co\u017e vede ke ztr\u00e1t\u011b sluchu. Po\u0161kodit se mohou nap\u0159\u00edklad st\u00e1\u0159\u00edm nebo hlasit\u00fdmi zvuky, kter\u00e9 p\u016fsob\u00ed po dlouhou dobu. Pr\u00e1v\u011b v dne\u0161n\u00ed dob\u011b je b\u011b\u017en\u00e9, \u017ee v\u011bt\u0161ina z n\u00e1s nem\u016f\u017ee cestovat dlouh\u00e9 trasy nebo posed\u011bt chv\u00edli bez sluch\u00e1tek v u\u0161\u00edch. I toto je zvuk, kter\u00fdm si m\u016f\u017eeme sluchov\u00fd org\u00e1n po\u0161kodit. Proto nen\u00ed na \u0161kody \u010das se sluch\u00e1tky v u\u0161\u00edch omezit. P\u0159esto se sluch\u00e1tek nemus\u00edte hned \u00fapln\u011b zbavit. Pokud nebudete m\u00edt muziku pu\u0161t\u011bnou na plno, nen\u00ed ohro\u017een\u00ed sluchu zase a\u017e tak vysok\u00e9. Dnes mezi mlad\u00fdmi u star\u0161\u00edmi p\u0159evl\u00e1d\u00e1 trend bezdr\u00e1tov\u00fdch sluch\u00e1tek. Tyto jsou sice modern\u00ed, ale docela zraniteln\u00e9.
