Human izwi umsipha

Izintambo kweqiniso vocal zitholakala phakathi komuntu pharyngeal endaweni ohlangothini lwesobunxele futhi kwesokudla ke. Ukumela ezimbili camera mucosa imfundo nokunwebeka, basuke welulela kusukela phambili kuya emuva. kuyaqina lawo landa ngenxa yokuba khona we sezicubu zezinzwa futhi kwemisipha e isakhiwo sabo. Isikhala phakathi lezi zinkampani ngokuthi glottis. Yezwi kungukuthi kuphela ezihilelekile ekwakhekeni imisindo, kodwa futhi ukukhonza umsebenzi ayisivikelo aphansi ipheshana zokuphefumula.

Umsindo akhiwa ngenxa tekuhlangani, futhi amaphaphu ukuguquguquka of nemisipha bedle umfutho womoya kokuphuma emaphashini. Kufanele kuqashelwe ukuthi izihambisimshini kumiswa imisindo kuzo zonke ezilwaneni ezinomgogodla, ifa apharathasi vocal, ngokwesilinganiso okufanayo. Ezinye izilwane ezincelisayo akudingeki-ke, uthando lwakhe lokuhlola abanye kunalokho ebuthakathaka. ezincelisayo eziningi, kodwa iqiniso futhi yephimbo zamanga. Kubantu, bona zisekujuleni kancane ngaphezu yangempela futhi kumiswa nemisindo azisetshenziswa.

Thina croaking izilwane zasemhlabeni nemisipha ezihilelekile ekwakhekeni imisindo, ubekwe Ingxenye engezansi "izwi lezindebe." Lezi emphethweni uqweqwe umqhewu lwamafinyila izungezwe onqenqemeni engaphakathi uqwanga arytenoid. ezihuquzelayo Abaningi abakwazi ukwenza umsindo. Phakathi kwabo kukhona nemisipha eqiniso aye Unwabu kanye geckos.

Lapho uphefumula umoya kuyinto ngokuqhubekayo futhi ngokushelela sidlula glottis. Kulokhu, kungcono pretty gengelezi. Air ukunyakaza Kwenziwa ngenxa umfutho yomoya. Lwenza imisipha expiratory yomuntu. Ngo inqubo ekwakhekeni slot umsindo ivaliwe futhi buhle nemisipha. Zacindezelwa isikhathi esifushane slot kuvula futhi uyaphuma lomoya. Khona-ke futhi, iphimbo beze ndawonye futhi baqala oscillate. Ngakho, ngesikhathi kumiswa umsindo ngaphakathi ukuhamba emoyeni esikhaleni iphazamisekile, futhi umoya ngokunyakaza vibrational. Kuye ngobukhulu kanye degree of umsipha ukungezwani, kanye ukuvama emoyeni nokudludliza, umsindo akhiwa ezahlukene eziphakeme. Ngo ukwakheka umsindo nazo bazibandakanye bronchi, amaphaphu kanye kuqhoqhoqho. Ukuze uthuthukise umsindo emzimbeni kukhona simiso resonators (umuntu iyona temlomo na acinene ingaphakathi).

Tifo letibangwa yezwi (ukuvuvukala) e abantu kungaba ngokuvamile zavele. Ngokuvamile, lokhu kwenzeka lapho komzimba, izifo ezibangelwa amagciwane, izinto imuncwe abakucasulayo le mucosa. Ukuvuvukala kungenzeka yashubisa nezwi overvoltage. Ukuvuvukala ulwelwesi lwamafinyila kungase kuhambisane ukwanda ubukhulu nemisipha, ukwehla esikhaleni. Ezimweni ikakhulukazi acute edema mucosal kungaholela Ukuvalwa ephelele umqhewu. Ngenxa yalokho, eyeka ukugeleza komoya emaphashini, futhi lesosikhathi lendoda iqala ukuba kuminyanise.

Ukuze zokuxilonga indlela esetshenziswa endoscopic nophenyo usebenzisa ikhamera ekhethekile, udokotela wethula ngobumnene emlonyeni noma ikhala. Inqubo wenziwa ngaphansi izinzwa wendawo, ngaleyo ndlela sigweme, ukuhlanza, ubuhlungu kanye nokuhlukumezeka isiguli.

Lolu cwaningo esiqondile vocal apharathasi iziyaluyalu eyenziwa ngumuntu stroboscope. Lokhu ukukhanyisa indlela ekhethekile kwenza okwashiwo kancane imvamisa izwi vibration. Le ndlela isetshenziswa sitholakele mechanical zezinzwa iziyaluyalu izwi kanye izimila ebulalayo ingozi ka esingaphansi milimitha. Phakathi stroboscopic Ungarekhoda inqubo zokuxilonga kuvidiyo elikuvumela ukuqapha isikhathi eside ngenxa yeziteleka kanye ukuqhathanisa isimo apharathasi vocal ngaphambi nangemva isicelo kokwelashwa noma imithi. Ikakhulukazi okubalulekile okwashiwo, lapho i operation ku yezwi.
