Amahedisethi esikhungo sezingcingo aklanyelwe ukudluliswa kwezwi, ngokuyinhloko axhuma izingcingo noma amakhompyutha ukuze asetshenziswe ehhovisi kanye nesikhungo sezingcingo. Izici zabo ezibalulekile namazinga afaka:
1.Umkhawulokudonsa wefrikhwensi omncane, olungiselelwe izwi. Amahedisethi ocingo asebenza phakathi kuka-300–3000Hz, amboza ngaphezu kuka-93% wamandla okukhuluma, aqinisekisa ukwethembeka kwezwi okuhle kakhulu kuyilapho kucindezela amanye amaza.
I-2.Professional electret microphone ukuze usebenze ngokuzinzile. Amamakrofoni ajwayelekile avame ukuwohloka ekuzweleni ngokuhamba kwesikhathi, okubangela ukuhlanekezela, kuyilapho amahedisethi esikhungo sezingcingo agwema le nkinga.
3.Ingasindi futhi ihlala isikhathi eside. Idizayinelwe ukusetshenziswa isikhathi eside, lawa mahedisethi abhalansisa ukunethezeka nokusebenza.
4.Ukuphepha kuqala. Ukusetshenziswa kwama-headphone isikhathi eside kungalimaza ukuzwa. Ukunciphisa lokhu, amahedisethi esikhungo sezingcingo ahlanganisa izifunda ezivikelayo, ezithobela izindinganiso zamazwe ngamazwe:
I-UL (Underwriter's Laboratories) ibeka umkhawulo wokuphepha ongu-118 dB ekuvezweni komsindo kungazelelwe.
I-OSHA (Occupational Safety & Health Administration) ikhawulela ukuchayeka komsindo okude ku-90 dBA.
Ukusebenzisa amahedisethi esikhungo sezingcingo kuthuthukisa ukusebenza kahle futhi kunciphisa izindleko.
Izesekeli: Izintambo zokunqamula ngokushesha (i-QD), okokudayila, okokudayila kwe-ID yofonayo, izikhulisamsindo, nezinye izingxenye.
Ukukhetha ihedisethi yekhwalithi:
Ukucaca komsindo
Ukudluliswa kwezwi okucacile, okungokwemvelo ngaphandle kokuhlanekezela noma okumile.
Ukuhlukaniswa komsindo okusebenzayo (ukunciphisa umsindo ozungezile ≥75%).
Ukusebenza kwemakrofoni
Imakrofoni ye-electret yezinga lochwepheshe enokuzwela okungaguquki.
Ukucindezela umsindo ongemuva womsindo opholile ongenayo/ophumayo.
Ukuhlolwa Kokuqina
I-Headband: Isinda emijikelezweni eguquguqukayo engu-30,000+ ngaphandle kokulimala.
Ingalo ye-Boom: Imelana nokunyakaza kwe-swivel okungu-60,000+.
Ikhebula: Amandla okubamba ama-40kg amancane; amaphuzu okucindezeleka aqinisiwe.
Ergonomics & Comfort
Idizayini engasindi (imvamisa engaphansi kuka-100g) enamakhushini ezindlebeni aphefumulayo.
Ibhande lasekhanda elilungisekayo lokugqoka isikhathi eside (amahora angu-8+).
Ukuthobela Ukuphepha
Ihlangabezana nemikhawulo yokuchayeka yomsindo we-UL/OSHA (≤118dB ukuphakama, ≤90dBA okuqhubekayo).
Ukujikeleza okwakhelwe ngaphakathi ukuvimbela ama-spikes omsindo.
Izindlela Zokuhlola:
Ukuhlolwa Kwensimu: Lingisa izikhathi zekholi zamahora angu-8 ukuze uhlole ukunethezeka nokubola komsindo.
Ukuhlolwa Kwengcindezi: Xhuma/ukhiphe ngokuphindaphindiwe izixhumi ze-QD (imijikelezo engu-20,000+).
Ukuhlolwa Kokulahla: imitha eyi-1 iwela endaweni eqinile akufanele ibangele umonakalo ekusebenzeni.
Ithiphu Yephrofayili: Bheka isitifiketi se-“QD (Ukunqamula Ngokushesha)” kanye neziqinisekiso zeminyaka engu-2+ ezivela kumabhrendi asayina ukwethembeka kwebanga lebhizinisi.
