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 esingasemva 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.
