Ndi mitundu ingati yaukadaulo woletsa phokoso lamutu mumadziwa?
Ntchito Yoletsa Phokoso ndiyofunika kwambiri pamakutu, imodzi ndikuchepetsa phokoso, kupewa kukweza kwambiri mawu pa sipika, potero kuchepetsa kuwonongeka kwa khutu. Chachiwiri ndikusefa phokoso la maikolofoni kuti muwongolere mawu komanso kuyimba bwino. Pali njira zambiri zopezera kuletsa phokoso. Mwachitsanzo, ANC,Chithunzi cha ENC, CVC, ndi DSP. Ndi angati a iwo omwe mumawadziwa?
Kuletsa phokoso kungathe kugawidwa mu kuchepetsa phokoso lopanda phokoso komanso kuchepetsa phokoso logwira ntchito.
Kuletsa phokoso lopanda phokoso ndikuletsanso phokoso lakuthupi, kuchepetsa phokoso lopanda phokoso kumatanthawuza kugwiritsa ntchito mawonekedwe a thupi kuti alekanitse phokoso lakunja kuchokera m'makutu, makamaka kupyolera mu mapangidwe a mutu wamutu wamutu, kukhathamiritsa kwa khutu la khutu, kuyika phokoso lomveka. zipangizo mkati mwa khushoni khutu… Ndi zina zotero kuti mukwaniritse kutsekemera kwamphamvu kwa chomvera. Kuchepetsa phokoso lopanda phokoso ndikothandiza kwambiri popatula maphokoso okwera kwambiri (monga mawu a anthu), nthawi zambiri amachepetsa phokoso ndi pafupifupi 15-20dB.
Kuletsa phokoso kumachitika pamene amalonda amalengeza ntchito yochepetsera phokoso ya mahedifoni: ANC, ENC, CVC, DSP… Lero tikambirana momwe amagwirira ntchito komanso momwe amasiyanirana.
ANC
ANC (Active Noise Control) Mfundo yogwirira ntchito ndi yakuti maikolofoni imasonkhanitsa phokoso lakunja lozungulira, ndiyeno makinawo amasandulika kukhala phokoso losinthika ndikuwonjezera kumapeto kwa nyanga, ndipo phokoso lomwe limamveka ndi khutu la munthu ndilo: Phokoso la chilengedwe + lopindika. chilengedwe phokoso, mitundu iwiri ya phokoso superimposed kukwaniritsa zomverera kuchepetsa phokoso, wopindula ndi iye mwini.
Chithunzi cha ENC
ENC (Environmental Noise Cancellation) imatha kupondereza 90% ya phokoso lozungulira, potero kuchepetsa phokoso lozungulira mpaka kupitirira 35dB. Kupyolera mu gulu la maikolofoni apawiri, kulunjika kwa wokamba nkhani kumawerengedwa molondola, ndikuteteza mawu omwe akuwongolera kumbali yaikulu, Chotsani mitundu yonse ya phokoso losokoneza chilengedwe.
DSP
DSP (kukonza ma siginecha a digito) imayang'ana kwambiri - komanso phokoso lotsika kwambiri. Ntchito
mfundo ndi yakuti maikolofoni amasonkhanitsa kunja phokoso chilengedwe, ndiyeno dongosolo amakopera n'zomveka yoweyula ofanana ndi kunja phokoso chilengedwe, kuletsa phokoso, motero kukwaniritsa bwino kuchepetsa phokoso zotsatira. Mfundo yochepetsera phokoso la DSP ndi yofanana ndi kuchepetsa phokoso la ANC. Komabe, phokoso labwino ndi loipa la kuchepetsa phokoso la DSP limasokonezana mwachindunji mu dongosolo.
Mtengo CVC
Mtengo CVC(Clear Voice Capture) ndiukadaulo wamawu wochepetsera phokoso. Imayang'ana kwambiri ma echo omwe amapangidwa panthawi yoyimba. Pulogalamu yoletsa phokoso la maikolofoni yaduplex imapereka ma call echo ndi ntchito zoletsa phokoso lozungulira, lomwe ndiukadaulo wapamwamba kwambiri wochepetsera phokoso pazida zam'manja za Bluetooth.
Tekinoloje ya DSP (kuletsa phokoso lakunja) imapindulitsa kwambiri wogwiritsa ntchito mahedifoni, pomwe CVC (kuletsa echo) imapindulitsa mbali ina ya kuyimba.
The Inbertec815M/815TMPhokoso la AI Kuchepetsa mutu wokhala ndi maikolofoni apamwamba kwambiri pochepetsa phokoso pogwiritsa ntchito maikolofoni awiri, algorithm ya AI kuti muchepetse phokoso kuchokera kumbuyo ndikungolola kuti mawu a wogwiritsa ntchito atumizidwe mbali ina. Chonde titumizirenisales@inbertec.comkuti mumve zambiri.
