Umsebenzi weUkuncishiswa komsindokubaluleke kakhulu kwihedsethi. Eyodwa ukunciphisa umsindo futhi igweme ukukhuliswa ngokweqile kwevolumu, ukuze kunciphise ukulimala endlebeni. Okwesibili ukuhlunga umsindo ukuthuthukisa ikhwalithi yomsindo nekhwalithi yokushayela.
Ukuncishiswa komsindo kungahlukaniswa kube ukuncishiswa komsindo ongezansi nokusebenzayo.
Ukuncishiswa komsindo nje nakhoUkuncishiswa komsindo ngokomzimba, ukuncishiswa komsindo ophayo kubhekisele ekusetshenzisweni kwezimpawu zomzimba ukuhlukanisa umsindo wangaphandle kusuka endlebeni, ikakhulukazi ngokuqamba kwekhanda le-headset, indlebe i-muffs ngaphakathi kwezinto zokwakha ezizwakalayo nokunye ukuze kufinyelelwe ukufakwa okuhle kwekhanda. Ukuncishiswa komsindo nje kusebenza kakhulu ekuhlukaniseni imisindo yemvamisa ephezulu (njengezwi lomuntu), futhi ngokuvamile kunciphisa umsindo cishe nge-15-20DB.
Ukuncishiswa komsindo osebenzayo yi-ANC yokuncipha komsindo oyinhloko i-ANC,ENGO, CVC, DSP nokunye okunjalo lapho abathengisi bekhuthaza umsebenzi wokunciphisa umsindo wamahedisethi.
Ukuncishiswa komsindo we-ANC
Ukulawulwa komsindo nge-ANC (Ukulawulwa komsindo okusebenzayo) kusebenza ngomgomo wokuthi imakrofoni iqoqa umsindo wangaphandle okukhona, bese uhlelo luluguqula lube yigagasi lomsindo elibunjiwe futhi likufaka endaweni ephelile. Umsindo wokugcina wezwakale yindlebe yomuntu yilena: umsindo omivea + amient umsindo ambilient umsindo, izinhlobo ezimbili zomsindo zihlehlise ukufeza ukuncishiswa komsindo wokuzwa, ozuzayo ngokwakho.
Ukuncishiswa komsindo okusebenzayo kungahlukaniswa kube ukuncishiswa komsindo okuphakelayo kokuphakelayo kanye nokuncishiswa komsindo okusebenzayo ngokuya ngezikhundla ezahlukahlukene zemakrofoni.
ENC Ukunciphisa umsindo
Enc (Ukukhanselwa komsindo kwezemvelo) ukukhanselwa okusebenzayo kwama-90% wokubuyiselwa kwemisindo okukhona, ngaleyo ndlela kunciphisa umsindo omite kuze kube yi-35DB, okuvumela abadlali ukuxhumana ngokukhululeka ngezwi. Ngokusebenzisa i-macrophone yamamakrofoni amabili, ukubalwa okuqondile kwesikhundla sesikhulumi, ngenkathi uvikela inkulumo enkulu yenkomba, susa zonke izinhlobo zomsindo wokuphazamiseka emvelweni.
Ukwehliswa komsindo we-DSP
I-DSP imfushane kakhulu ekusebenzeni kwesiginali yedijithali. Ikakhulukazi umsindo ophakeme futhi ophansi wemvamisa. Umqondo ukuthi imakrofoni ithatha umsindo ovela emvelweni yangaphandle, bese uhlelo lukopisha igagasi lomsindo elicijile elilingana nomsindo okhona, ukukhansela umsindo nokuthola umsindo ongcono. Umgomo wokuncishiswa komsindo we-DSP uyafana nokwehliswa komsindo we-ANC. Kodwa-ke, umsindo omuhle futhi ongemuhle we-DSP ukhansula omunye komunye ngohlelo.
Ukuncishiswa komsindo we-CVC
Sula Ukuthwebula Izwi (i-CVC) kungubuchwepheshe be-software yesoftware yomsindo. Ikakhulukazi e-echo eyenziwe ngesikhathi socingo. Isoftware ye-Drawlex ye-Dunkharsone yomsindo ephelele inikezela nge-Call Echo nemisebenzi ye-Amient Handsation Imisebenzi, okungukuthi ubuchwepheshe bokunciphisa umsindo obuthuthuke kakhulu phakathi kwamakhanda e-Bluetooth phone.
Ubuchwepheshe be-DSP (Ukuqeda umsindo bangaphandle) ikakhulukazi buzuzisa umsebenzisi we-headset, kuyilapho i-CVC (eqeda i-echo) ikakhulukazi izuza olunye uhlangothi lwengxoxo.
