Low simbi yomuropa muropa vangava chokuita kusanzwa

Kana vanhu vane yakaderera simbi tigutsikane muropa, zvinogona kutungamirira inonzi simbi-kushaikwa kupererwa, hunobata kunopindirana utano. Ongororo Recent kwakaratidza kuti, kunze mukuru muutera, chirwere vangava chokuita kunzwa vanotaura.

Zvakaipira kupererwa neropa

Kudzidza akawana kuti vakuru vanotambura kupererwa neropa vari pangozi yokubatwa kunzwa matambudziko munguva maviri kupfuura utano. chirwere ichi chinonziwo kurasikirwa yaisanganisa pakunzwa.

Inini kunotoda yokuedzwa vakuru 300,000 kubva kuPennsylvania. Vakwikwidzi vaiva 21 kusvika 90 makore, kunoreva zera aiva nemakore 50. Masayendisiti vakaedza kusarudza kudzidza varwere, vose vaiva simbi kushaikwa, uye kunzwa vanotaura.

Zvatinoziva kunzwa kurasikirwa?

Pane 3 Mapato nokunzwa kurasikirwa: sensorineural (kana perceptual) izvo kunokonzera kukuvara munzeve, kukuvara tsinga, kuti kunyorerana nzeve kuuropi kana kukanganisika pfungwa kwebasa; conductive dzinoratidzwa murombo permeability nokurira, uye mubatanidzwa kusanzwa, kubatanidza zvinhu yapfuura maviri.

aibatanidza zvirwere

Vaongorori vakawana kuti vanhu vane kupererwa neropa vaiva 2.4 nguva yakawanda kubatwa wemishonga uye 1,8 nguva - sensorineural kusanzwa, zvichienzaniswa vaya vane chirwere ichi chakanga chisiri. Asi pakanga pasina ukama pakati simbi kushaikwa uye matambudziko nenzeve, oddly zvakakwana, kwete, maererano masayendisiti.

The pamusoro yapfuura nemiedzo vachitungamirirwa Kathleen Shniffer, mudzidzi weHurumende College of Medicine muPennsylvania ripoti, akaudzwa kuti pane zvimwe zvikonzero nei siyana dzesimbi sensorineural kusanzwa anogona chokuita nomumwe.

neurosensory vanotaura

Okunzwisisa kusanzwa anogona kuitika somugumisiro kuvadza ropa duku nemidziyo nzeve, uye kupererwa neropa kungakonzera chaizvoizvo izvi. Somuenzaniso, simbi kushaikwa kunotungamirira matambudziko wokufambisa ropa, iro kunokanganisa muviri wose zvavo, saka unogona kukuvadza ropa midziyo diki kukura nyore. Mukuwedzera, chirwere kunowanzokonzera kuparadzwa myelin mumuhara kuti tsinga, kusanganisira avo kuti kubatanidza nzeve uye uropi.

Kutaura zvazviri, vanotsvakurudza hypothesized kuti kupererwa neropa anogona chokuita sensorineural kusanzwa, uye kwete conductive. Somuenzaniso, mune imwe kwokutanga Mushumo nokudzidza nyaya iyi muTaiwan kutaurwa kuti kungoerekana okunzwisisa kusanzwa angatanga mumaawa 72 Varwere nesimbi kukanganisika.

vakaperekedza vachivavhiringidza

Ukuwo, zvikuru conductive anonzi "zvemaziso" matambudziko, akadai kuzara munzeve, hwomukova mitumbi vavatorwa kana kukuvadza eardrum. Ndokusaka vasayendisiti vakafunga kuti ichi mhando kunzwa kurasikirwa kunogona nechokuita kupererwa neropa.

Asi, sezvo vatsvakurudzi vakaona, pasinei nokuti varwere pasi kwevari nesimbi yakawanda pangozi kusanzwa, asi chaizvoizvo yakasimbiswa ukama pakati zvirwere maviri. Miedzo inoratidza kururama mugumisiro, sezvo zvakanga zvisiri vaiona yakasiyana pabonde mapati, kunyange vaine chirwere cheshuga kana tsika dzakaipa, uye regai tarisa kuti kumanikidzwa zviratidzo.

Mune ramangwana riri vakaronga kuti azodzidza mumagazini ino uwane. Sezvo simbi kushayiwa muropa kunogona kunetsa kunzwa kurasikirwa, pamwe tinogona kumisa panowanikwa kunzwa kurasikirwa varwere, kubvisa zviratidzo kupererwa neropa.
