Okwangoku, ungcoliseko lwengxolo lube ngomnye wemiba emithandathu ephambili yokungcoliseka kwendalo.
Sesiphi isandi esichazwa njengengxolo?
Inkcazo yenzululwazi yeyokuba isandi esikhutshwa ngumzimba ovakalayo xa singcangcazela ngokungaqhelekanga sibizwa ngokuba yingxolo. Ukuba isandi esikhutshwa ngumzimba wesandi sidlula imigangatho yokukhupha ingxolo yokusingqongileyo emiselwe lilizwe kwaye sichaphazela ubomi obuqhelekileyo babantu, ukufunda kunye nomsebenzi, sikubiza ngokuba lungcoliseko lwengxolo yokusingqongileyo.
Eyona nto iyingozi kakhulu yengxolo kumzimba womntu ibonakala kumonakalo wokuva. Umzekelo, ukuvezwa kwexesha elide kwingxolo ephindaphindiweyo, okanye ukuvezwa kwingxolo ye-super decibel ixesha elide ngexesha, kuya kubangela ukungeva kwe-neurological. Ngelo xesha, ukuba isandi esiqhelekileyo sidlula i-85-90 decibels, siya kubangela umonakalo kwi-cochlea. Ukuba izinto ziqhubeka ngolu hlobo, ukuva kuya kuncipha ngokuthe ngcembe. Xa sele ujongwe kwindawo enee<em>decibel ezili-140 nangaphezulu, kungakhathaliseki ukuba lifutshane kangakanani na ixesha lokuba sesichengeni, umonakalo wokuva uya kwenzeka, yaye kwiimeko ezimandundu, oko kuya kubangela umonakalo osisigxina ongenakulungiseka ngokuthe ngqo.
Kodwa ngaba ubusazi ukuba ukongeza kumonakalo othe ngqo ezindlebeni nasekuveni, ingxolo inokuchaphazela amehlo kunye nombono wethu.
●Uvavanyo olufanelekileyo lubonisa oko
Xa ingxolo ifikelela kwi-90 decibels, uvakalelo lweeseli ezibonakalayo zomntu luya kuncipha, kwaye ixesha lokuphendula lokuchonga ukukhanya obuthathaka liya kuba lide;
Xa ingxolo ifikelela kuma-95 ee<em>decibels, ama-40 ekhulwini abantu baye bahlanjululwa ngabafundi yaye bangaboni kakuhle;
Xa ingxolo ifikelela kwi-115 decibels, inkoliso yabantu ukuqhelana nokuqaqamba kokukhanya kuyehla ukuya kutsho kumanqanaba awahlukeneyo.
Ke ngoko, abantu ababekwindawo enengxolo ixesha elide bathanda ukonakaliswa kwamehlo njengokudinwa kwamehlo, iintlungu zamehlo, i-vertigo, kunye neenyembezi ezibonakalayo. Olu phando lukwafumanise ukuba ingxolo inokwehlisa umbono wabantu ngombala obomvu, oblowu, nomhlophe ngama-80%.
Kutheni kunje? Ngenxa yokuba amehlo neendlebe zomntu ziqhagamshelwe ukusa kumlinganiselo othile, ziqhagamshelwe kwiziko lemithambo-luvo. Ingxolo inokuchaphazela inkqubo yemithambo-luvo esembindini yengqondo yomntu ngelixa yonakalisa ukuva. Xa isandi sigqithiselwa kwilungu leendlebe lomntu-indlebe, ikwasebenzisa inkqubo yemithambo-luvo yobuchopho ukuyidlulisela kwilungu elibonakalayo lomntu-iliso. Isandi esininzi siya kubangela umonakalo we-nerve, okhokelela ekunciphiseni kunye nokuphazamiseka komsebenzi wokubonwayo jikelele.
Ukunciphisa ingozi yengxolo, sinokuqala kule miba ilandelayo.
Eyokuqala kukuphelisa ingxolo kumthombo, oko kukuthi, ukuphelisa ukwenzeka kwengxolo ngokusisiseko;
Okwesibini, inokunciphisa ixesha lokuvezwa kwindawo yengxolo;
Ukongeza, unokunxiba ii-earphones ezichasene nengxolo ukuze uzikhusele;
Kwangaxeshanye, yomeleza ukwazisa nokufundisa ngeengozi zongcoliseko lwengxolo ukuze wonke umntu azi ngokubaluleka kunye nemfuneko yokunciphisa ungcoliseko lwengxolo.
Ngoko kwixesha elizayo ukuba umntu wenza ingxolo ekhethekileyo, unokumxelela ukuba “Shhh! Nceda uthule, uyangxola emehlweni am.
