Ukuqonda umlinganiselo wokunciphisa ingxolo (NRR)
Isinyathelo sokuqala xa ukhetha i-muffs yokudubula indlebe kukuqonda ukuba yintoni i-NRR (Umlinganiselo wokuNcitshiswa kweNxolo) kunye nendlela ekuchaphazela ngayo ukunciphisa isandi kwindawo enikiweyo. Ukuze kuthathwe njengesixhobo esisebenzayo sokukhusela iindlebe, isimumu sendlebe, iplagi okanye esinye isixhobo KUFUNEKA sinciphise ukuvezwa kwesandi somsebenzisi ngomyinge othile. Umgangatho woKhuseleko oPhuculweyo kufuneka unciphise ukuvezwa kwesandi ngokupheleleyo ngama-50 ekhulwini okanye ngaphezulu. Olu luhlu lwabelwe ixabiso lamanani, elibizwa ngokuba yiNgxoxo yokuNcitshiswa kweNgxoxo (NRR). Le NRR isetyenziswa kwi-avareji yokuvezwa kwesandi isixhobo esicuthayo, kwaye eli xabiso liposwe kwileyibhile yesimufu sendlebe ngumenzi. Xa kuziwa ekudubuleni, i-NRR ephezulu, ingcono, njengoko inika ukhuseleko oluphezulu kumonakalo wokuva. Ukudubula i-ear muffs ngokuqhelekileyo kune-NRR ye-22-34.
Oko kuthethwa, i-NRR ephezulu iqinisekisa kuphela inqanaba eliphezulu lokhuseleko xa lisetyenziswe ngokufanelekileyo kwaye lifakwe ngokufanelekileyo. I-ear muffs kufuneka itywine ngokufanelekileyo malunga nendlebe, kungabikho zithuba, okanye ukusebenza kwazo kuncitshiswe kakhulu.
Ngaphaya koko, uhlobo lwendawo yokudubula okuyo inokuchaphazela i-NRR oyifunayo. Isandi sivakala ngakumbi kwindlu engaphakathi, isithuba sokudubula esivaliweyo kunakwindawo yangaphandle. Ukufumana ibhalansi efanelekileyo ye-NRR ngokuthuthuzela kunye nokusebenziseka ngokulula kuya kukunceda uve ngokukhuselekileyo.
Ukubaluleka kokuthuthuzela kunye nokufaneleka
Ukufaneleka kunye nokuthuthuzela kungundoqo xa ukhetha i-ear muffs, kwaye naliphi na ixesha elongezelelweyo elichithwe ukudubula lifuna ukhuseleko lokuva olukhululekile olunokunxitywa iiyure ngexesha ngaphandle kokubangela ukukhathala kweendlebe, intloko ebuhlungu okanye enye into engathandekiyo. I-headband kufuneka ilungiswe ngokupheleleyo kwaye ifakwe, kwaye kufuneka ibonelele ngokukhuselekileyo kumsebenzisi ngaphandle kokubangela intlungu, ukuphazamiseka okanye ukungalingani.
Iikomityi zendlebe zibalulekile ekuthuthuzelekeni. I-Earmuffs kufuneka ibe neekomityi zendlebe ezenziwe nge-foam okanye ijeli: zombini izixhobo zinikela isitywina esingcono kunye nentuthuzelo engcono. Uxinzelelo olujikeleze iindlebe luyancipha kakhulu. Amaqhosha kunye nokutshintsha kufuneka kube lula ukubambelela kwiiglavu. Ezinye i-ear muffs zenziwe ngobunjineli bentloko kunye neendlebe ukuba zive ngathi ziyinxalenye yakho kunento oyinxibileyo.
Kukwakho nendawo yokuphefumla onokucinga ngayo. Ezinye i-muffs zendlebe ezinolwakhiwo oluvulekileyo lwe-mesh zidlula umoya phezu kweendlebe, ngoko ukubila akukhi ezindlebeni zakho (into ethuthuzelayo kwimozulu eshushu okanye xa udubula kakhulu). Kufanelekile ukuzama izibini ezimbalwa, kwaye ujonge uphononongo oluvela kubasebenzisi.
Ukuqina kunye nezixhobo
Ukudubula ii-muffs zendlebe, kufuneka ujonge ukuqina. Kuba zenzelwe ukusetyenziswa rhoqo, ngokufanelekileyo akufuneki ukuba zaphulwe ngexesha elikhawulezayo. Izinto ezikumgangatho ophezulu ezifana neeplastiki eziqinisiweyo kunye nentsimbi engenasici yeyona nto ilungileyo yokujonga xa uvavanya i-muffs yendlebe. Uzakugqibela ugcina imali, njengoko izixhobo ezomeleleyo zemufu yendlebe yokudubula zithetha ukuba akusayi kufuneka uzitshintshe rhoqo.
Umgangatho owakhiweyo unokubandakanya iihenjisi kunye namanye amalungu alungelelanisiweyo omelele ngokwaneleyo ukuba angamelana nohlengahlengiso oluphinda-phindayo ngaphandle kokwaphuka, kunye nezinto ezenza iimufu zingangenwa manzi okanye zikwazi ukumelana namanzi, ukuze zingonakali ngenxa yokubila okanye ukuba kuqalise ukunetha ngelixa uphumile.
Ngaphezu koko, ezinye ii-muffs zendlebe zokudubula zinokuba neendawo ezinokuthi zithathelwe indawo njengeecushion zendlebe kunye neebhanti zentloko. Xa la malungu ephela, umsebenzisi akayi kufuna ukuthenga enye iperi ye-muffs yendlebe njengokutshintshwa, kodwa kuphela iindawo ezisecaleni.
Iimpawu ezongezelelweyo ekufuneka ziqwalaselwe
Iimuffs ezininzi zeendlebe zokudubula zinenani leempawu ezongezelelweyo ezihambelana nomsebenzi wazo osisiseko. I-elektronikhi i-ear muffs ibonisa ukukhulisa isandi sezandi ezikwinqanaba elisezantsi ngelixa zibonelela ngokhuseleko kwimigangatho yengxolo ephezulu, enokuthi ngenye indlela ibangele umonakalo wokuva. Oku kuneengenelo zokuvumela ulwazi lwemeko olubukhali kunye nonxibelelwano.
Ubunakho beBluetooth bukwangumsebenzi omnandi, ovumela umntu onxibileyo ukuba aqhagamshele kwisixhobo esiphathwayo kwaye asasaze umculo okanye athathe iifowuni, ngokubamba okunokwenza usuku olude kuluhlu okanye kwibala elimnandi ngakumbi.
Ezinye i-ear muffs nazo zine-microphone eyakhelwe-ngaphakathi kunye nezithethi zokunxibelelana ngeendlela ezimbini, nto leyo ilungele ukudutyulwa kweqela. Ukuqwalasela ezi mpawu zongezelelweyo kunye nokuba zibaluleke kangakanani ezo mpawu kuwe, ngokusekelwe kwimikhwa yakho yokudubula, kunokukunceda ukhethe ezona muffs zifanelekileyo zendlebe.
Ixabiso vs. ukusebenza
Ixabiso elichasene nokusebenza yenye ingqalelo xa ucinga ngokudubula i-muffs yendlebe. Iimodeli eziphakamileyo eziphezulu zivame ukubonelela ngokunciphisa ingxolo engcono, intuthuzelo ngakumbi, kunye neempawu ezongezelelweyo - kodwa nazo zibiza kakhulu. Kuya kufuneka ucinge malunga nokuba ixabiso elongezelelweyo liya kuxabisa inkcitho eyongezelelweyo.
I-Mid-range ye-elektroniki i-ear muffs idla ngokuba lulungelelwano oluhle phakathi kwexabiso kunye nokusebenza. Iimodeli zodidi oluphakathi ziya kuba neempawu ezaneleyo zokubonelela ukusebenza okwaneleyo ngokwemiqathango yokunciphisa ingxolo kunye nokuthuthuzela, ngaphandle kweendleko ezigqithisileyo zokuphela okuphezulu. Iimuffs zendlebe eziphakathi zilukhetho olulungileyo kubadubuli besiqhelo, okanye abo bakwibhajethi engqongqo.
Iimuffs zendlebe ezitshiphu aziyi kuqhuba kakuhle phantsi kweemeko ezinzima kwaye ziqwalaselwe. Nangona kunjalo, i-muffs yendlebe efikelelekayo ibonisa ukhetho lohlahlo lwabiwo-mali olukwinqanaba lokungena kwaye, ngaphandle kokusilela kwabo, basenakho ukunika ukhuseleko olululo olusisiseko olululo. Ukuba ufuna kuphela i-muffs yendlebe yakho kumsitho wosuku olunye, kuya kuba kufanelekile ukuba uzikhethe njengeseti ye-muffs yendlebe egciniweyo. Kuya kufuneka ujonge macala onke ukuze ufumane umdlalo wakho ogqibeleleyo. Zama ukuthelekisa iimpawu, izibonelelo kunye neendleko kwiindidi ezahlukeneyo zamaxabiso, kwaye ufunde ezinye iiphononongo.
isiphelo
Zeziphi ezona ngqwalasela zibalulekileyo xa udubula imifu yendlebe? Ungaqinisekisa njani ukuba ukhetha ezona muffs zilungileyo zokudubula iindlebe ukugcina ukuva kwakho iminyaka ezayo? Ngeentlobo ezininzi ezahlukeneyo kunye nezimbo zokuvala indlebe, zonke zinamabango ahlukeneyo kunye neempawu, kunokuba nzima ukwazi ukuba ujonge ntoni. Kweli nqaku, siza kuxoxa ngezona zinto zibalulekileyo ekufuneka uzigcine engqondweni ukuze ukhethe phakathi kwezona muffs zilungileyo zokudubula kwaye ubeke phambili ukhuseleko lwakho lomntu. Inkalo ebaluleke kakhulu yokukhusela ukuva kukukhusela ngokwawo, kulinganiswa nexabiso elinikwe le mveliso ngumenzi. Ibizwa ngokuba yi-NRR, okanye ukuNcitshiswa kweNgxolo. Imigangatho yamva nje yokhuselo lokuva ye-FDA icebisa ukuba elona xabiso liphezulu lokalisho lwalo naliphi na iqhekeza elinye lokhuselo lokuva kufuneka libe yi-33 dB. Oku kuthetha ukuba iya kubonelela ngesandi esingxolayo esingama-33 dB. Uluhlu lokudubula i-ear muffs kufuneka luchaze ngokucacileyo ukulinganisa kwabo kwe-NRR, ukubonelela umsebenzisi ngesikhokelo esithile kwinqanaba lokukhusela abaya kubonelela. Nangona kunjalo, kubalulekile ukukhumbula ukuba ukulinganisa kusekelwe kwiimeko ezithile, kwaye abathengi abayi kuhlala bekwazi ukuphindaphinda ezo meko zokulinganisa abathengi ngokuchanekileyo. Enye imeko enjalo esetyenziselwa ukulinganisa i-muffs ye-ear muffs luluhlu lwethagethi yompu, apho abadubuli bavavanya i-muffs ngokudubula ngokuphindaphindiweyo kuyo kumgama omfutshane (iimitha ezi-2). Ngelixa oku kuvavanya i-muffs yendlebe, akunakufane kwenzeke ukuba ube udubula into ekujoliswe kuyo kumjelo wendlebe yakho. Ngeso sizathu, kubalulekile ukuthathela ingqalelo ubuntofontofo bemifuziselo yendlebe oyithengayo.
