Noise-canceling headsets yog ib hom headsets uas txo suab nrov los ntawm ib txoj kev.
Lub suab nrov-tso tawm lub mloog pob ntseg ua haujlwm los ntawm kev siv cov microphones thiab hluav taws xob sib txuas ua haujlwm kom tshem tawm cov suab nrov sab nraud. Lub microphones ntawm lub mloog pob ntseg tuaj tos cov suab nrov sab nraud thiab xa mus rau hauv hluav taws xob circuitry, uas tom qab ntawd tsim cov suab nrov tawm tsam kom tshem tawm cov suab nrov sab nraud. Cov txheej txheem no yog hu ua kev cuam tshuam kev puas tsuaj, qhov twg ob lub suab tsis tso tseg ib leeg tawm. Qhov tshwm sim yog tias lub suab nrov sab nraud tau txo qis, tso cai rau tus neeg siv hnov lawv cov ntsiab lus suab kom meej meej. Tsis tas li ntawd, qee lub suab nrov tshem tawm lub mloog pob ntseg kuj tseem muaj kev sib cais suab nrov, uas lub cev thaiv cov suab nrov sab nraud los ntawm kev siv cov khoom siv suab nrov hauv lub khob pob ntseg.
Tam sim nosuab nrov-tso tseg headsetsnrog mic muab faib ua ob hom suab nrov-tso tseg: passive suab nrov tshem tawm thiab nquag suab nrov tshem tawm.
Kev txo qis suab nrov Passive yog cov txheej txheem uas txo cov suab nrov hauv ib puag ncig los ntawm kev siv cov khoom tshwj xeeb lossis cov khoom siv. Tsis zoo li lub suab nrov txo qis, tsis muaj suab nrov txo tsis tas yuav tsum siv cov khoom siv hluav taws xob lossis cov sensors los ntes thiab tawm suab nrov. Nyob rau hauv sib piv, passive suab nrov txo cia siab rau lub cev lub zog ntawm cov khoom los nqus, xav txog los yog cais lub suab nrov, yog li txo cov propagation thiab cuam tshuam ntawm lub suab nrov.
Passive suab nrov-tshem tawm headsets feem ntau tsim qhov chaw kaw los ntawm kev qhwv lub pob ntseg thiab siv cov khoom siv suab nrov xws li silicone earplugs los thaiv cov suab nrov sab nraud. Yog tias tsis muaj kev pabcuam thev naus laus zis, lub mloog pob ntseg rau lub chaw ua haujlwm nrov tuaj yeem thaiv cov suab nrov nrov, tab sis tsis tuaj yeem ua dab tsi txog lub suab nrov tsawg.
Lub hauv paus ntsiab lus tseem ceeb ntawm kev siv lub suab nrov tshem tawm yog lub hauv paus ntsiab lus cuam tshuam ntawm nthwv dej, uas cuam tshuam lub suab nrov los ntawm cov suab tsis zoo thiab tsis zoo, thiaj li ua tiav cov suab nrov.suab nrov-tshem tawm cov nyhuv. Thaum ob yoj yoj crests los yog yoj troughs sib ntsib, qhov kev hloov ntawm ob lub nthwv dej yuav raug muab tso rau ntawm ib leeg, thiab qhov kev vibration amplitude kuj yuav ntxiv. Thaum nyob rau hauv lub ncov thiab hav, qhov kev vibration amplitude ntawm lub xeev superposition yuav raug muab tso tseg. ADDASOUND wired suab nrov tshem tawm lub mloog pob ntseg tau siv lub suab nrov tshem tawm tshuab.
Ntawm lub suab nrov nrov tshem tawm lub mloog pob ntseg lossis lub suab nrov nrov tshem tawm lub pob ntseg, yuav tsum muaj ib lub qhov lossis ib feem ntawm nws tig mus rau sab nraud ntawm pob ntseg. Qee tus neeg yuav xav tias nws yog dab tsi. Qhov no yog siv los sau cov suab sab nraud. Tom qab cov suab nrov sab nraud tau sau, processor hauv lub pob ntseg yuav tsim ib qho kev tiv thaiv suab nrov nyob rau hauv qhov kev taw qhia rau lub suab nrov.
Thaum kawg, qhov chaw tiv thaiv lub suab nrov thiab lub suab ua si hauv lub mloog pob ntseg raug xa mus ua ke, kom peb tsis tuaj yeem hnov lub suab sab nraud. Nws yog hu ua lub suab nrov tshem tawm vim nws tuaj yeem txiav txim siab seb puas suav cov suab nrov los tiv thaiv.
