Ukulahlekelwa kokuzwa emsebenzini

Ukulahleka kokuzwa emsebenzini kungumonakalo endlebeni yangaphakathi evela emsindweni noma kunyakaza ngenxa yezinhlobo ezithile zemisebenzi.

Ngokuhamba kwesikhathi, ukuvezwa okuphindaphindwayo ngomsindo omkhulu nomculo kungadala ukulahleka kokuzwa.

Imisindo engaphezulu kwama-decibel angama-80 (dB, isilinganiso somsindo noma amandla wokudlidliza komsindo) kungadala ukudlidlizela okukhulu ngokwanele ukulimaza indlebe yangaphakathi. Lokhu kungenzeka kakhulu ukuthi kwenzeke uma umsindo uqhubeka isikhathi eside.

• I-90 dB - iloli elikhulu amamitha ama-5 (4.5 metres) kude (izithuthuthu, izithuthuthu zeqhwa, nezinjini ezifanayo kusuka ku-85 kuye ku-90 dB)
• I-100 dB - amanye amakhonsathi e-rock
• I-120 dB - i-jackhammer cishe ngamamitha amathathu (1 imitha) kude
• I-130 dB - injini ye-jet esuka ebangeni elingu-100 (30 metres)

Umthetho ojwayelekile wesithupha ukuthi uma udinga ukumemeza ukuze uzwakale, umsindo ukusebanga elingalimaza ukuzwa.

Eminye imisebenzi inobungozi obukhulu bokulahlekelwa ukuzwa, njenge:

• Ukugcinwa komhlaba kwezindiza
• Ukwakhiwa
• Ukulima
• Imisebenzi ehilela umculo ophakeme noma imishini
• Imisebenzi yezempi ebandakanya ukulwa, umsindo wendiza, noma okunye okuthunyelwe okukhulu komsindo

E-United States, imithetho ilawula ukuvezwa kwemisindo ephezulu yomsebenzi evunyelwe. Kokubili ubude bokuchayeka nezinga le-decibel kuyabhekwa. Uma umsindo uphezulu noma ungaphezulu kwamazinga aphezulu anconyiwe, udinga ukuthatha izinyathelo ukuvikela ukuzwa kwakho.

Uphawu oluyinhloko ukulahleka kokuzwa okuyingxenye noma okuphelele. Ukulahleka kokuzwa cishe kuzoba kubi ngokuhamba kwesikhathi ngokuvezwa okuqhubekayo.

Umsindo endlebeni (tinnitus) ungahambisana nokulahleka kokuzwa.

Ukuhlolwa komzimba ngeke kubonise noma yiziphi izinguquko ezithile ezimweni eziningi. Ukuhlolwa okungenziwa kufaka phakathi:

• I-audiology / audiometry
• I-CT scan yekhanda
• I-MRI yobuchopho

Ukulahleka kokuzwa kuvame kakhulu unomphela. Izinhloso zokwelashwa uku:

• Vimbela ukulahleka kokuzwa okuqhubekayo
• Thuthukisa ukuxhumana nanoma yikuphi ukulalela okusele
• Thuthukisa amakhono okubhekana nesimo (njengokufunda izindebe)

Ungadinga ukuthi ufunde ukuhlala nokulahlekelwa ukuzwa. Kunezindlela ongazifunda ukwenza ngcono ukuxhumana nokugwema ukucindezeleka. Izinto eziningi endaweni okuyo zingathinta indlela ozizwa ngayo futhi uqonde kahle okushiwo abanye.

Ukusebenzisa insiza yokuzwa kungakusiza uqonde inkulumo. Ungasebenzisa futhi amanye amadivayisi ukusiza ngokulahlekelwa ukuzwa. Uma ukulahleka kokuzwa kunzima ngokwanele, ukufakwa kwe-cochlear kungasiza.

Ukuvikela izindlebe zakho kunoma yikuphi ukulimala okuqhubekayo nokulahleka kokuzwa yingxenye ebalulekile yokwelashwa. Vikela izindlebe zakho lapho uvezwa emisindweni enkulu. Gqoka amapulagi endlebe noma okokufaka izindlebe ukuvikela ekulimaleni komshini omkhulu.

Qaphela izingozi ezihlobene nokuzilibazisa ezifana nokudubula isibhamu, ukushayela izithuthuthu zeqhwa, noma eminye imisebenzi efanayo.

Funda ukuthi ungazivikela kanjani izindlebe zakho lapho ulalele umculo ekhaya noma emakhonsathini.

Ukulahlekelwa ukuzwa kuvame ukuhlala unomphela. Ukulahleka kungahle kube kubi kakhulu uma ungathathi izinyathelo zokuvikela ukulimala okuqhubekayo.

Shayela umhlinzeki wakho wezempilo uma:

• Unokulahlekelwa ukuzwa
• Ukulahleka kokuzwa kuya ngokuya kuba kubi
• Uba nezinye izimpawu ezintsha

Izinyathelo ezilandelayo zingasiza ukuvimbela ukulahleka kokuzwa.

• Vikela izindlebe zakho lapho uvezwa emisindweni enkulu. Gqoka ama-plugs endlebe noma okokuvikela izindlebe uma useduze nemishini enomsindo.
• Qaphela izingozi zokuzwa kusuka emisebenzini yokuzilibazisa efana nokudubula isibhamu noma ukushayela izimoto ezihamba eqhweni.
• UNGALALELI umculo ophakeme isikhathi eside, kufaka phakathi ukusebenzisa amahedfoni.
