Zonke iintlobo zeempawu zokurhoxisa ingxolo yee-headsets, Ngaba ucacile?

Zingaphi iintlobo zetekhnoloji yokurhoxisa ingxolo ye-headset oyaziyo?

Umsebenzi wokuCima ingxolo ubalulekile kwii-headsets, enye kukunciphisa ingxolo, ukuphepha ukukhulisa isandi esigqithisileyo kwisithethi, ngaloo ndlela kuncitshiswa umonakalo endlebeni. Okwesibini kukucoca ingxolo kwi-mic ukuphucula isandi kunye nomgangatho wokufowuna. Kukho iindlela ezininzi ezahlukeneyo zokuphumeza ukurhoxiswa kwengxolo. Umzekelo, iANC,I-ENC, CVC, kunye neDSP. Bangaphi kubo obaziyo?

Ukurhoxiswa kwengxolo kunokwahlulwa kuncitshiswe ingxolo kunye nokunciphisa ingxolo esebenzayo.

Ukucinywa kwengxolo ye-Passive ikwakukucinywa kwengxolo yomzimba, ukuncitshiswa kwengxolo ye-passive kubhekisa kusetyenziso lweempawu zomzimba ukwahlula ingxolo yangaphandle endlebeni, ngakumbi ngoyilo lwentloko yentloko ye-headset, ukulunga kwe-acoustic ye-cushion cavity, ukubeka isandi esifunxayo. imathiriyeli ngaphakathi kumqamelo wendlebe… Kwaye njalo ukuphumeza isandi esibonakalayo se-headset. Ukunciphisa ingxolo engenzi nto kusebenza kakhulu ekwahluleni izandi eziphezulu (ezifana namazwi abantu), ukunciphisa ingxolo ngokubanzi malunga ne-15-20dB.

Ukucinywa kwengxolo kuxa amashishini ebhengeza umsebenzi wokunciphisa ingxolo wee-headphones: i-ANC, i-ENC, i-CVC, i-DSP… Yeyiphi imigaqo-siseko yezi teknoloji zine zokunciphisa ingxolo, kwaye yintoni indima yazo? Namhlanje siza kuthetha ngendlela asebenza ngayo kwaye ahluke njani.

I-ANC
I-ANC (I-Active Noise Control) Umgaqo osebenzayo kukuba i-microphone iqokelela ingxolo ye-ambient yangaphandle, kwaye ke inkqubo iguqula ibe yi-wave yesandi eguqulwayo kwaye idibanise ekupheleni kophondo, kunye nesandi esiviweyo yindlebe yomntu: Ingxolo yendawo engqongileyo + inverted ingxolo yokusingqongileyo, iindidi ezimbini zengxolo ezibekwe phezulu ukuze kuthotywe ingxolo yeemvakalelo, umxhamli nguye ngokwakhe.

I-ENC
I-ENC (I-Environmental Noise Cancellation) inokucinezela ngempumelelo i-90% yengxolo ebuyela umva, ngokwenjenjalo inciphisa ingxolo yendawo ukuya kuthi ga kwi-35dB. Ngokusebenzisa uluhlu lwamakrofoni amabini, ukuqhelaniswa kwesithethi kubalwa ngokuchanekileyo, ngelixa ukhusela ilizwi elijoliswe kuyo kwicala eliphambili, Susa zonke iintlobo zengxolo yokuphazamiseka kwindawo.

I-DSP

I-DSP (ukulungiswa komqondiso wedijithali) ijolise ikakhulu phezulu - kunye nesandi esisezantsi. Ukusebenza

umgaqo kukuba imakrofoni iqokelela ingxolo yokusingqongileyo yangaphandle, kwaye ke inkqubo ikopisha isandi esibuyela umva esilingana nesandi sokusingqongileyo sangaphandle, irhoxisa ingxolo, ngaloo ndlela ifumana isiphumo esingcono sokunciphisa ingxolo. Umthetho-siseko wokunciphisa ingxolo ye-DSP uyafana nokunciphisa ingxolo ye-ANC. Nangona kunjalo, ingxolo elungileyo kunye nengalunganga yokunciphisa ingxolo ye-DSP iphazamisana ngokuthe ngqo kwinkqubo.

CVC

CVC(Sula iVoice Capture) yitekhnoloji yelizwi yokunciphisa ingxolo. Ijolise ikakhulu kwii-echoes ezenziwe ngexesha lomnxeba. Isoftware yokurhoxisa ingxolo yemakrofoni ephindwe kabini ibonelela nge-echo yokufowuna kunye nemisebenzi yokurhoxisa ingxolo ye-ambient, eyona teknoloji yokunciphisa ingxolo ephezulu kwii-headsets zeBluetooth.

Itekhnoloji ye-DSP (ukucima ingxolo yangaphandle) inceda kakhulu umsebenzisi we-headset, ngelixa i-CVC (i-echo yokukhansela) inceda kakhulu kwelinye icala lefowuni.
