Muva nje, kuye kwaba nokwanda kokulahleka kwezindlebe kubantu abaneminyaka engaphezu kwe-60. Indoda endala ekhaya isanda kukhuluma kakhulu, kulula ukuyilwa, futhi futhi ithambekele ekuthukutheleni? Uma ukusebenza okunjalo kuzothathelwa izinyathelo ezinqala, kungahle kuphakamise ukuthi ukulalelwa kwabadala kuyancipha.

NgoMashi 3, "usuku lwendlebe yothando" lukazwelonke libuye lube "usuku lwezindlebe zothando" lwamazwe omhlaba. Ake sikhulume ngokulahleka kokuzwa okuhlobene nobudala nokuguga komzimba. Yini asebekhulile okufanele bayenze uma benqaba ukusebenzisa izinsiza-kuzwa?

Ngokwamazinga kazwelonke, izinga lokulalelwa kwezindlebe lihlukaniswe izigaba eziyisithupha ezilandelayo.

I-1. Ukuzwa okujwayelekile: ngaphansi kwe-25dB (decibel). Kungokobubanzi obujwayelekile bokuzwa.

I-2. Ukulahleka kokuzwa okumnene: 25 kuya ku-40 dB. Isiguli asizwa noma sizwa kuphela ukulahleka okuncane kokuzwa futhi ngokuvamile asithinti amakhono okuxhumana ngamazwi.

3. Ukulahlekelwa okulingene kokuzwa: 41 kuye ku-55 dB. Emvelweni webanga elincane, umsindo wangemuva, nezingxoxo ezihlangene, uzothola ukuthi awukwazi ukuzwa kahle; ivolumu ye-TV izwakala kakhulu; kuvela isimo sokuthimula, futhi isinqumo sokuzwa siqala ukuncipha.

I-4. Ukulalela okuphakathi ngokulinganiselayo ukuya kokunetha kakhulu: 56 to 70 dB. Ukuzwa izingxoxo ezinkulu nemisindo yemoto.

I-5. Ukulahlekelwa okukhulu kwezindlebe: 71 to 90 dB. Iziguli zizwa imisindo ephakeme noma izingxoxo ezisezingeni eliseduze futhi zize ziwubone umsindo noma onkamisa abakhona, kodwa hhayi amakhonsathi.

6. Ukulahlekelwa okukhulu kwezindlebe: kukhulu kune-90dB. Iziguli azikwazi ukuthembela nje ekuzweni ukuxhumana nabanye, futhi zidinga ukufundwa kwezindebe nosizo lomzimba.

Abantu abadala abanokukhubazeka kokuzwa banokucabanga okubi nenkumbulo embi kunalabo abanokuzwa okujwayelekile. Ukuzwa ukulahleka, ukukhuthazeka kobuchopho komsindo kuyehla, futhi kuthatha amandla amaningi ukucubungula umsindo, ngaleyo ndlela kudele amanye amandla ekuqaleni ayesetshenziselwa ukubhekana nenkumbulo nokucabanga. Ngokuhamba kwesikhathi, ikhono lokucabanga nokukhumbula asebekhulile kuzokwehla. Empilweni, abantu asebekhulile bazoba nobunzima ekuxhumaneni, kunciphise ukuxhumana, njll., Baze balahlekelwe yintshisekelo yabo yezenhlalo, bazihlukanise kancane kancane ezweni langaphandle, babe isimungulu futhi baphansi.

Ngakho-ke, lapho sekutholakele ukulahleka kokuguga kwabadala, umndeni kufanele uthathe asebekhulile esibhedlela ukuze uyothola i-otolaryngology, ikhanda nentamo ukuhlinzwa ngesikhathi (uphenyo olujwayelekile lwezokwelapha, ukuhlolwa kwendlebe, nokuhlolwa kobuhlungu bokuzwa kwezwi) yokulahleka kokuzwa.
