Kungakhathaliseki ukuthi usendaweni yokudubula noma uyozingela, ukuzwa kwakho kuyimpahla yakho ebaluleke kakhulu. Lesi yisizathu esenza ukuthi ama-muffs ezindlebeni abe yigiya okufanele libe nalo kuwo wonke umdubuli. Njengoba kunezinketho eziningi kangaka ezitholakalayo emakethe namuhla, kungaba nzima ukuthola ipheya efanele yezidingo zakho. Yingakho sihlanganise lo mhlahlandlela.
Okuqukethwe:
1. Ukuqonda isilinganiso sokunciphisa umsindo (NRR)
2. Ukubaluleka kokunethezeka nokufaneleka
3. Ukuqina kanye nezinto zokwakha
4. Izici ezengeziwe okufanele zicatshangelwe
5. Inani ngokumelene nokusebenza
Ukuqonda isilinganiso sokunciphisa umsindo (NRR)
Isinyathelo sokuqala lapho ukhetha ama-muffs ezindlebeni ukuqonda ukuthi iyini i-NRR (Isilinganiso Sokunciphisa Umsindo) nokuthi ithinta kanjani ukuncishiswa komsindo endaweni ethile. Ukuze kuthathwe njengethuluzi elisebenzayo lokuvikela izindlebe, i-muff yendlebe, ipulaki noma enye idivayisi KUMELE inciphise ukuvezwa komsindo komsebenzisi ngenani elithile. Isilinganiso sokuvikela esithuthukisiwe kufanele sehlise ukuvezwa komsindo okuphelele ngamaphesenti angama-50 noma ngaphezulu. Lesi silinganiso sabelwe inani lenombolo, elibizwa ngokuthi Isilinganiselwa Sokuncishiswa Komsindo (NRR). Le NRR isetshenziswa ekuvezweni komsindo okumaphakathi idivayisi ekwehliswayo, futhi leli nani lithunyelwa kulebula ye-muff yendlebe ngumkhiqizi. Uma kuziwa ekudubuleni, ukuphakama kwe-NRR, kungcono, njengoba inikeza ukuvikeleka okukhulu ekulimaleni kokuzwa. Ama-muffs ezindlebeni zokudubula ngokuvamile ane-NRR engama-22-34.
Uma sekushiwo, i-NRR ephakeme iqinisekisa kuphela izinga eliphezulu lokuvikela lapho isetshenziswa kahle futhi ifakwe ngokufanele. Ama-muffs endlebeni kufanele avale kahle endlebeni, kungabikho zikhala, noma ukusebenza kwawo kunciphe kakhulu.
Ngaphezu kwalokho, uhlobo lwendawo yokudubula okuyo lungathinta i-NRR oyidingayo. Umsindo uzwakala kakhulu endaweni engaphakathi, evalekile yokudubula kunasendaweni engaphandle. Ukuthola ibhalansi efanele ye-NRR ngokunethezeka nokusebenzisa kalula kuzokusiza ukuthi uzwe ngokuphepha.
Ukubaluleka kokunethezeka nokufaneleka
Ukufaneleka nokunethezeka kuyisihluthulelo lapho ukhetha ama-muffs ezindlebeni, futhi noma isiphi isikhathi esinwetshiwe esichithwa ukudubula sidinga ukuvikeleka kokuzwa okunethezekile okungagqokwa amahora amaningi ngesikhathi ngaphandle kokubangela ukukhathala kwezindlebe, ikhanda elibuhlungu noma okunye ukungakhululeki. Ibhande lasekhanda kufanele lilungiseke ngokugcwele futhi lihlanganiswe, futhi kufanele linikeze ukulingana okuphephile komsebenzisi ngaphandle kokubangela ubuhlungu, ukungakhululeki noma ukungalingani.
Ama-ear cups abalulekile ekududuzeni. Ama-earmuffs kufanele abe nezinkomishi zendlebe ezigxiliwe ezenziwe ngegwebu noma ijeli: zombili izinto ezisetshenziswayo zinikeza uphawu olungcono nokunethezeka okungcono. Ukucindezela okuzungeze izindlebe kuyancipha kakhulu. Izinkinobho namaswishi kufanele futhi kube lula ukubamba namagilavu. Amanye ama-ear muff akhiwe ngendlela yekhanda nezindlebe ukuze azizwe sengathi ayingxenye yakho kunento oyigqokile.
Kukhona nokungena komoya ongacabanga ngakho. Amanye ama-muffs ezindlebeni anokwakhiwa kwe-open mesh adlulisa umoya ezindlebeni, ukuze umjuluko ungakhi ezindlebeni zakho (into eduduzayo esimweni sezulu esishisayo noma lapho udubula kakhulu). Kuyafaneleka ukuzama amapheya ambalwa, futhi ubheke izibuyekezo ezivela kubasebenzisi.
Ukuqina nezinto zokwakha
Ukuze udubule ama-muffs endlebeni, udinga ukubheka ukuqina. Njengoba enzelwe ukusetshenziswa njalo, akufanele aphulwe ngokushesha. Izinto zekhwalithi ephezulu ezifana namapulasitiki aqinisiwe nensimbi engagqwali kuyinketho engcono kakhulu ongayibheka lapho uhlola ama-muffs ezindlebeni. Uzogcina wonge imali, njengoba izinto eziqinile ze-muff endlebeni yokudubula kusho ukuthi ngeke kudingeke ukuthi uzishintshe njalo.
Ikhwalithi eyakhiwe ingase ihlanganise amahinge nezinye izingxenye ezilungisekayo eziqine ngokwanele ukumelana nokulungiswa okuphindaphindiwe ngaphandle kokuphuka, kanye nezinto ezenza ama-muff angangeni manzi noma okungenani amelane namanzi, ukuze angonakali ngenxa yokujuluka noma uma liqala ukuna ngenkathi uphumile.
Ngaphezu kwalokho, amanye ama-muffs endlebeni okudubula angaba nezingxenye ezishintshwayo njengama-cushions ezindlebeni namabhande asekhanda. Lapho lezi zingxenye ziguga, umsebenzisi ngeke adinge ukuthenga amanye ama-muffs endlebeni esikhundleni, kodwa izingxenye ezisele kuphela.
Izici ezengeziwe okufanele zicatshangelwe
Ama-muff amaningi wesimanjemanje anezici eziningi ezengeziwe ezihambisana nomsebenzi wawo oyisisekelo. Ama-ear muff ka-elekthronikhi afaka ukukhuliswa komsindo kwemisindo yezinga eliphansi kuyilapho inikeza ukuvikeleka kumazinga aphezulu omsindo, okungadala ukulimala kokuzwa. Lokhu kunezinzuzo zokuvumela ukuqwashisa ngezimo ezibukhali kanye nokuxhumana.
Amandla e-Bluetooth nawo angukuthinta okuhle, okuvumela ogqokile ukuthi axhumeke kudivayisi yeselula futhi asakaze umculo noma ashaye izingcingo, ngokuthinta okungenza usuku olude ebangeni noma enkundleni inambitheke kakhudlwana.
Amanye ama-ear muffs nawo anemakrofoni eyakhelwe ngaphakathi kanye nezipikha zokuxhumana okubili, okuhle kakhulu ekudubuleni kweqembu. Ukucabangela lezi zici ezengeziwe nokuthi lezo zici zibaluleke kangakanani kuwe, ngokusekelwe emikhubeni yakho yokudubula, kungakusiza ukhethe ama-muffs afaneleka kakhulu ezindlebeni.
Intengo iqhathaniswa nokusebenza
Inani eliqhathaniswa nokusebenza kungenye into ecatshangwayo lapho ucabanga ngokudubula ama-muffs ezindlebeni. Amamodeli asezingeni eliphezulu avame ukunikeza ukuncishiswa komsindo okungcono, ukunethezeka okwengeziwe, nezici ezengeziwe - kodwa futhi abiza ngaphezulu. Kuzodingeka ucabange ukuthi inani elengeziwe lizozifanela yini izindleko ezengeziwe.
I-Mid-range electronic ear muffs ngokuvamile iwukuvumelana okuhle phakathi kwentengo nokusebenza. Amamodeli ebanga elimaphakathi ngokuvamile azoba nezici ezanele ukuze anikeze ukusebenza okwanele mayelana nokunciphisa umsindo nokunethezeka, ngaphandle kwezindleko ezidlulele zokuphela okuphezulu. Ama-muffs ezindlebeni aphakathi nendawo ayinketho enhle kubadubuli abavamile, noma labo abasabelomali esiqinile.
Ama-muffs ashibhile ezindlebeni ngeke asebenze kahle ngaphansi kwezimo eziyinselele kanye nokucutshungulwa ngokucophelela Kodwa-ke, ama-muffs ashibhile ezindlebeni amelela izinketho zesabelomali sezinga lokungena futhi, naphezu kokushiyeka kwazo, asenganikeza isivikelo sokuzwa esihle esiyisisekelo. Uma udinga kuphela ama-muffs wakho endlebeni ngomcimbi wosuku olulodwa, kungaba kuhle ukuwakhetha njengesethi yama-muffs endlebeni ayisipele. Uzodinga ukuqalaza ukuze uthole ukufana kwakho okuphelele. Zama ukuqhathanisa izici, izinzuzo nezindleko phezu kwamazinga entengo ahlukahlukene, futhi ufunde okunye ukubuyekezwa.
Isiphetho
Yiziphi izici ezibaluleke kakhulu zokudubula ama-muffs ezindlebeni? Ungaqiniseka kanjani ukuthi ukhetha ama-muffs ezindlebeni ezingcono kakhulu ukuze ulondoloze ukuzwa kwakho iminyaka ezayo? Ngezinhlobo eziningi ezahlukene nezitayela zama-muffs ezindlebeni, zonke ezinezimangalo nezici ezihlukene, kungaba nzima ukwazi ukuthi yini okufanele uyibheke. Kulesi sihloko, sizoxoxa ngezinto ezibaluleke kakhulu okufanele uzikhumbule ukuze ukwazi ukukhetha phakathi kwama-muffs ezindlebeni angcono kakhulu okudubula futhi ubeke phambili ukuvikela kwakho siqu. Isici esibaluleke kakhulu sokuvikela izindlebe ukuvikela ngokwako, kukalwa ngenani elinikezwe lo mkhiqizo ngumkhiqizi. Kubizwa nge-NRR, noma Isilinganiselwa Sokuncishiswa Komsindo. Amazinga akamuva e-FDA okuvikela ukuzwa aphakamisa ukuthi inani eliphezulu lesilinganiso sanoma iyiphi ingxenye yesivikelo sokuzwa kufanele libe ngu-33 dB. Lokhu kusho ukuthi izohlinzeka ngomsindo onomsindo omncane ongu-33 dB. Ama-muffs ezindlebeni zohlu lokudubula kufanele asho ngokucacile isilinganiso sawo se-NRR, anikeze umsebenzisi umhlahlandlela othile wezinga lokuvikela azolinikeza. Kodwa-ke, kubalulekile ukukhumbula ukuthi isilinganiso sisekelwe kuzimo ezithile, nokuthi abathengi ngeke bahlale bekwazi ukuphinda lezo zimo ukuze bathole izilinganiso ezinembile zabathengi. Esinye sesimo esinjalo esisetshenziswa ukukala ama-muffs ezindlebeni ububanzi bethagethi yesibhamu somshini, lapho abadubuli behlola khona ama-muffs ngokuqhumisa ukuqhuma okuphindaphindiwe kuwo besebangeni elifushane (amamitha amabili). Nakuba lokhu kuhlola ama-muffs ezindlebeni, mancane amathuba okuthi udubule okuqondiwe endlebeni yakho. Ngaleso sizathu, kubalulekile ukucabangela ukunethezeka kwama-muffs endlebeni owathengayo.
