Uhlobo lokunciphisa ingxolo yee-headsets

Umsebenzi weukunciphisa ingxoloibaluleke kakhulu kwi-headset. Enye kukunciphisa ingxolo nokuphepha ukunyuswa kwesandi esigqithisileyo, ukuze kuncitshiswe umonakalo endlebeni. Okwesibini kukucoca ingxolo ukuphucula umgangatho wesandi kunye nomgangatho wokufowuna.

Ukunciphisa ingxolo kunokwahlulwa kube kukwenziwa kunye nokunciphisa ingxolo esebenzayo.

Ukucutha ingxolo engenzi nto nayoukunciphisa ingxolo yomzimba, Ukunciphisa ingxolo yokunciphisa ibhekisa kusetyenziso lweempawu zomzimba ukwahlula ingxolo yangaphandle endlebeni, ngakumbi ngoyilo lwebhanti yentloko ye-headset eqinile, ukulungelelaniswa kwe-acoustic ye-ear muffs cavity, i-ear muffs ngaphakathi kwezixhobo zokufunxa isandi kunye nokunye. Ukufikelela kwi-insulation yesandi esibonakalayo se-headsets. Ukunciphisa ingxolo engenzi nto kusebenza kakhulu ekwahluleni izandi eziphezulu (ezifana nelizwi lomntu), kwaye ngokubanzi kunciphisa ingxolo malunga ne-15-20dB.

Ukunciphisa ingxolo yeyona nto iphambili yokunciphisa ingxolo i-ANC,I-ENC, CVC, DSP kunye nokunye xa abathengisi bekhuthaza umsebenzi wokunciphisa ingxolo yee-headsets.

Ukunciphisa ingxolo yeANC

I-ANC Active Control Noise Control (Active Noise Control) isebenza kumgaqo wokuba i-microphone iqokelela ingxolo yendawo yangaphandle, emva koko inkqubo iyiguqule ibe yi-wave yesandi eguqulelwe kwaye idibanise ekupheleni kophondo. Isandi sokugqibela esiviwe yindlebe yomntu sesi: Ingxolo ekwindawo engqongileyo + ingxolo ye-ambient yesigaba, iindidi ezimbini zengxolo ezibekwe phezulu ukuze kuthotywe ingxolo yeemvakalelo, umxhamli nguye ngokwakhe.

Ukunciphisa ingxolo esebenzayo inokwahlulwa ibe yi-feedforward esebenzayo yokunciphisa ingxolo kunye nengxelo esebenzayo yokunciphisa ingxolo ngokweendawo ezahlukeneyo zemakrofoni yokuthatha.

Ukunciphisa ingxolo ye-ENC

I-ENC (I-Environmental Noise Cancellation) lucimo olusebenzayo lwe-90% yengxolo yokubuyisela umva kwi-ambient, ngaloo ndlela inciphisa ingxolo yendawo ukuya kutsho kuma-35dB, nto leyo evumela abadlali ukuba banxibelelane ngokukhululekileyo ngelizwi. Ngokusebenzisa uluhlu lwemakrofoni ezimbini, ukubala okuchanekileyo kwendawo yesithethi, ngelixa ukhusela intetho ekujoliswe kuyo ephambili, susa zonke iintlobo zengxolo yokuphazamiseka kokusingqongileyo.

Ukunciphisa ingxolo ye-DSP

I-DSP imfutshane kwi-digital processing signal. Ikakhulu kwingxolo ephezulu kunye nesezantsi. Ingcamango kukuba imakrofoni ithatha ingxolo evela kwindawo yangaphandle, kwaye ke inkqubo ikopisha i-wave yesandi esijikelezayo esilingana nomsindo ojikelezayo, ukucima ingxolo kunye nokufezekisa ukunciphisa ingxolo engcono. Umthetho-siseko wokunciphisa ingxolo ye-DSP uyafana nokunciphisa ingxolo ye-ANC. Nangona kunjalo, ingxolo elungileyo kunye nengalunganga ye-DSP iyacima enye nenye ngqo kwisistim.

Ukunciphisa ingxolo yeCVC

I-Cal Voice Capture (CVC) yiteknoloji yelizwi yokunciphisa ingxolo. Ikakhulu kwi-echo eyenziwe ngexesha lokufowuna. Isoftware yokurhoxisa ingxolo yemakrofoni ephindwe kabini ibonelela nge-echo yokufowuna kunye nemisebenzi yokurhoxisa ingxolo ye-ambient, eyona teknoloji yokunciphisa ingxolo iphambili phakathi kwee-headsets zeBluetooth.

I-teknoloji ye-DSP (ukuphelisa ingxolo yangaphandle) inceda kakhulu kumsebenzisi we-headset, ngelixa i-CVC (ukuphelisa i-echo) inceda kakhulu kwelinye icala lengxoxo.
