Indlela ukukhetha izinsizakuzwa? Indlela ukukhetha okuhle futhi engabizi kuzwa ngoba umuntu osekhulile?

Ukuzwa ukulahleka noma ukulahleka oluphelele ke - ke akuyona neze isigwebo sentambo ngokuba indoda, futhi uphile sinazo kungenzeka. Nokho, izinga lokuphila ngesikhathi esifanayo kungaba ngokuphawulekayo ukuwohloka. Caught in nesimo esifanayo, ungalilahli ithemba futhi ulahlekelwe inhliziyo. Ake sizame ukubhekana yini engenziwa ukwenza ngcono isimo engeyinhle, futhi kanjani ukukhetha izinsizakuzwa bayakwazi ukubuya umzimba impahla elahlekile.

Kungani ukuzwa liwohloka

Izizathu ukwehlisa nokucija bezibona imisindo, kunezindlela eziningi. Okuvame kakhulu kanti legkoustranimaya - ukunqwabelana imali ethe nesibabule indlebe umsele. Futhi ekulalelweni okuthintekayo yobunzima obabangelwa izifo ezithathelwanayo. Ezimweni ezinjalo kwanele uthintane onguchwepheshe futhi ibhekane Inkambo yokwelashwa aqokwe kuye. Ngenxa ukulahlekelwa kukuzwa ingabuyiswa maduzane.

Ukuwohloka izinga bezibona imisindo kungathinta umsebenzi okhokhelwayo. Umsindo ekusebenzeni imishini esakhiweni, lo elikhulu club umculo, ukuqhuma kwezibhamu e ngokudubula zemibukiso - zonke lezi zenzo omubi empilweni yomuntu.

Ziyini izimbangela eziyinhloko zalokhu of ubuthulu, yilezi ezilandelayo:

• ikhanda ukuhlukumezeka noma indlebe;
• kwasekuzalweni indlebe futhi indlebe canal;
• imiphumela ukuchayeka ezithile kwamaphilisi;
• Ukwelashwa ngamakhemikhali nokushiswa ngemisebe,
• izinguquko ubudala;
• yofuzo.

Umthelela ubuthulu ukuphila komuntu

ukungezwa kahle esiphazamisayo zokuxhumana ezijwayelekile. Man has uhlobo kakhulu ukuzwa amazwi interlocutors, nalabo yena, udinge ukuphinda abazokusho izikhathi eziningana. Ukuze uqonde okushiwo ingxoxo, umuntu oyisithulu kufanele njalo bheka abantu ebusweni. Catch intambo ingxoxo iba nzima, kanti isiguli ngokuvamile iyaphendula engafanele.

Ukunganakwa ngokuphazamisa noma kunjalo engenakwenzeka. ukwelashwa esifike ngesikhathi kudokotela kungasiza ngcono ukuzwa. Ezimweni eziningi ungakwazi ukuza kokuzwa usizo. Ukusetshenziswa Its lihambisana izinyathelo zokwelapha ngeke kakhulu ngcono empilweni yakho iyonke.

izinkomba yezokwelapha

Naphezu inkimbinkimbi kubonakala sengathi kunokuthula kulesi Impendulo yombuzo kanjani ukukhetha izinsiza-kuzwa kuphela, kuyacaca ukuthi lokhu akufanele. Isekelwe kuphela ukubonakala umqhubi umsindo noma ukudayiswa kwayo ngemali eyifanele, ungathenga idivayisi ezisiza nje kugcine kwecala, kodwa ngeke senze isimo sishube ezimbi. Ngakho, okungalungile ivolumu kulungiselelwa angabangela wegazi abanomfutho wegazi ophakeme iziguli ukwanda, okuyoholela umphumela oyinhlekelele.

Abanye abantu hhayi Kunconywa ukusebenzisa amadivaysi zvukoulavlivayuschih. Lokhu kunjalo, ikakhulu kufanele sinake uma uhlela ukuthenga nezinsiza kokuzwa asebekhulile. Izimo isicelo iziguli oyingozi noma ezingamahlalakhona zengqondo kanye sezinzwa uhlelo izifo. Qaphela kulabo ihlangabezana nezinkinga umsebenzi inhliziyo, imithambo yegazi, noma ezingamahlalakhona indlebe isifo.

Ukuze uthole ukuthi lapho kuzwa kungcono ukukhetha, udinga bonana nodokotela wakho futhi wenze ukuhlolwa ezidingekayo. Udokotela wendlebe ngeke ukuxilonga kokuzwa ukuthola imiphumela kusezingeni audiogram lokwehliswa bezibona umsindo kulo lonke uhla imvamisa.

Kube sezingeni ukulimala ukuzwa

Kwezokwelapha, kukhona amazinga eziningana ubuthulu, lapho kudingeka ethile kuzwa. Indlela ukukhetha kahle, kuzosenza a somhleli esekelwe ngemiphumela yocwaningo eziningi.

Kuthathwa ukuzwa ikhono Sasivame ukuzwa imisindo ehlukahlukene ama-decibel angu-zero abe amabili. Konke lingaphandle kwebanga esibekiwe, kubhekwa ubuthulu:

• omnene - kusukela decibel angu amabili amahlanu;
• ngezinga isilinganiso - kusuka amahlanu ama-decibel angu ayisikhombisa;
• degree ezinzima - audibility kusuka ayisikhombisa ukuba ama-decibel angu ayisishiyagalolunye;
• degrees superheavy - decibel angu ayisishiyagalolunye nangaphezulu.

Ukuze siphendule ngendlela efanele umbuzo kanjani ukukhetha izinsizakuzwa, kufanele wazi ukuthi ngokuvumelana nesimiso yesenzo bona bonke bawela izigaba ezimbili eziyisisekelo: i-analog futhi digital. Ake sibheke izindawo ngamunye wabo.

analog amadivayisi

Izinsiza-kuzwa ngokulinganayo ukukhiqiza yokukhulisa izitshengiselo zamatshe zonke ticale microphone. Ngenxa yalokho, imisindo babe ongaqondakali, kuyokhanya ngempela. Kodwa labo imisindo ukuthi nangaphambi kokuba isiguli sibe waqonda evamile, sizobuye beqiniswe isiginali ye-analog futhi babe ngokweqile elikhulu.

Ngenxa yalokho, umuntu uthola ngokweqile ongcolile nomsindo futhi ilahlekelwa intelligibility. Njengomthetho, yesikhathi eside ukusetshenziswa okunjalo amadivayisi kuholela okhushuliwe ukucasuka futhi akathandi ukusetshenziswa kwabo njalo. Inzuzo enkulu izinhlelo analog wukuthi kuba izinsizakuzwa engabizi intengo imali okuyinto ebenza bathandwe kuze kube yilolu suku.

amadivaysi Digital

Amadivayisi empeleni amakhompyutha yesikhumbuzo. Umgomo we operation isekelwe okhulisa ukukhetha amasignali engenayo. Lapho ekucubunguleni umsindo engenayo abahlukene enkulumweni yabo futhi umsindo. Ngenxa yalokho, ngezinga eliphezulu intelligibility yokukhuluma womuntu ukwehla kanyekanye imisindo nezingahlobene nendaba. Ukuze unesifo sikashukela abantu abaphethwe ikhanda, okungcono ukuzwa nezinsiza - labo ekhansela umsindo.

Ukuze wenze okungcono kakhulu emihle-tune idivaysi nemingcele ngazinye kuzwa, kufanele uqaphe ngokwengeziwe ukuchitha i audiogram. Kukhula inani lamaphuzu okusebenzayo kubonelelwe nesifundo, kungakalindeleki ngokunembe kakhudlwana umshini vulela umuntu. Ngenxa yalokho, waqonda umsindo kuyoba sobala.

Izici imibhobho

amadivaysi Digital anemisila uhlelo umbhobho usebenza izindlela ezimbili.

amadivaysi zvukoperedayuschie kokuqondisa unikeze isignali izinga kusukela into etholakala eduze onenkinga yokuzwa kahle umuntu. Lena ukhetho kangcono abantu babephila ukuphila esekusithekeni futhi avamile.

imibhobho Omnidirectional zikuvumela ukuzwa interlocutors abamzungezile. Izinsiza abantu ohola yokuphila asebenzayo, eziningi talking, futhi nezingane zibhekwa izinsiza-kuzwa ngeke ivumelane kakhulu.

Intuthuko yamuva nje kumasistimu zvukopererabatyvayuschih wakhe i microphone oluhambelana ohlangothini. Letindlela bayakwazi ahlele imisindvo ezizungezile futhi ulungise kubo, kungakhathaliseki vector isiqondiso. Ukushintsha umsindo ambient isimo kuholela le usuke othomathikhi ohlelweni ofanele izinga bezibona.

Izinhlobo izinsizakuzwa

amadivaysi Zvukoperedayuschie babe nezinkolelo ezihlukahlukene amafomu zangaphandle. Khetha ezifanele kungaba esekelwe Umklamo umshini, usayizi waso, ubuchwepheshe esetshenziswa, kanye umbala.

Ukuze nikwazi ukhethe izinsizakuzwa ngokuhambisana nezidingo nasendleleni yabo yokuphila, kudingeka sicabangele izinzuzo kanye nezinzuzo models ethandwa kakhulu. bahlukene ngohlobo indawo ku:

• -ear - zitholakala indlebe noma indlebe canal;
• BTE - ibekwe ngemuva kwendlebe.

Idivayisi ngemuva kwendlebe noma ngaphakathi - lokho ukukhetha

I sobala amadivayisi izinzuzo-isiteshi zihlanganisa nomklamo stylish kanye nosayizi amancane ezenza engabonakali ngokuphelele, ikakhulukazi imibala akhethwe kahle. Ngo-imishini enzelwa nesineke ngayinye ngokuhambisana isakhiwo yokwakheka indlebe.

Ububi angabhekwa ukuthi izinsizakuzwa kuyinto compact kuba yinkimbinkimbi ukusebenzisa nokugcina. Umthelela earwax njengoba endaweni enobudlova kuthinta iqophelo insimbi. Imininingwane waseGileyadi amadivayisi abe nemingcele ungavumeli ukuba sizisebenzise ukuze abantu ngezinga elithile ukulahlekelwa kukuzwa phezu kwama-decibel angu ayisikhombisa. Asihambisani miniature amathuluzi kanye labo angaphansi njalo izinqubo ukuvuvukala ezindlebeni. Futhi, musa batusa amadivaysi alalelwayo compact ukusebenzisa izingane nasebekhulile.

BTE onobuhle ngaphandle nibonakala kubantu nilungile ezibukeka zingalungile besiyoba sikhulu futhi ayimkhangi. icala amadivayisi Tebuciko offset ngu umsindo ikhwalithi ngisho nalapho izinga extra osindayo ubuthulu esikwaziyo namashumi amabili ama-decibel angu. Kalula yesondlo nokwethembeka ukwenza BTE kumadivayisi adumile phakathi asebekhulile.

Impilo inkonzo izinsizakuzwa

Ukuze iyunithi wakhonza isikhathi eside ngangokunokwenzeka, idinga ukunakekelwa efanele. Ngokuhambisana aid imfundo evela indlebe yakho kufanele ukunganakwa njalo. Ukuze izinyathelo zokunqanda kuyadingeka ngezikhathi uxhumane sesevisi. Njengoba ukuphila konke onqunyiwe izinga ukuzwa amadivayisi ongafinyelela kweminyaka emihlanu noma eyisithupha.

Ebhekene nazo isidingo ukusebenzisa izinsiza kokuzwa, kufanele kuqondwe ukuthi umsindo eliphezulu nenduduzo kuxhomeke efanele Ukukhetha kanye ukulungiswa kwekhwalithi kulandzelana nekuhlunga tinsita. Lokhu kufanele kusize i isipiliyoni nokuqeqeshwa udokotela, Udokotela wezindlebe, ogama msebenzi ukuxazulula lesiguli inkinga ngendlela engcono ngaye.
