Suab nrov-tso tseg cov taub hau yog ib hom headsets uas txo suab nrov los ntawm qee txoj kev.
Cov suab nrov-tso tseg ua haujlwm ua haujlwm los ntawm kev siv cov kev sib xyaw ntawm microphones thiab hluav taws xob hluav taws xob kom nquag thim tawm suab nrov sab nraud. Lub microphones ntawm lub taub hau lub suab nrov thiab xa nws mus rau hluav taws xob hluav taws xob, uas yog tsim cov suab sib txawv los txo cov suab nrov sab nraud. Cov txheej txheem no yog hu ua kev cuam tshuam kev puas tsuaj, qhov twg ob lub suab vuag under. Qhov tshwm sim yog tias lub suab sab nraud tau txo qis, cia tus neeg siv tau hnov lawv cov ntsiab lus audio kom meej meej. Tsis tas li ntawd, qee cov khw muag khoom nrov tseem muaj cov suab nrov rho tawm, uas lub cev tawm ntawm lub suab nrov sab nraud los ntawm kev siv lub suab nrov hauv pob ntseg pob ntseg.
Tam sim nosuab nrov-txeeb chawNrog MIC tau muab faib ua ob hom suab nrov-tshem tawm: passive suab kaw thiab nrov nrov.
Passive suab nrov yog cov txheej txheem uas txo lub suab nrov hauv ib puag ncig los ntawm kev siv cov ntaub ntawv tshwj xeeb lossis khoom siv. Tsis zoo li cov suab nrov tiv thaiv, txo cov suab nrov tsis tas yuav tsum tau siv cov khoom siv hluav taws xob lossis cov sensors los kuaj xyuas thiab ntaus suab nrov. Hauv kev sib piv, lub suab nrov txo qis ntawm cov khoom siv lub cev ntawm cov khoom siv kom nqus, muaj suab nrov, yog li txo cov suab nrov thiab cuam tshuam ntawm lub suab nrov.
Passive suab-txeeb chaw headsets feem ntau ua qhov chaw kaw los ntawm qhwv pob ntseg thiab siv cov ntaub ntawv insulating xws li Silicone Earplugs los thaiv cov suab nrov sab nraud. Yog tsis muaj kev pab cuam ntawm thev naus laus zis, lub mloog pob ntseg tsis muaj suab nrov xwb, tab sis tsis tuaj yeem ua txhua yam hais txog lub suab nrov tsawg.
Cov ntsiab lus tseem ceeb ua ntej ntawm cov suab nrov ncua tawm yog lub hauv paus ntsiab lus cuam tshuam, uas neutralizes lub suab nrov los ntawm kev ua kom zoo thiab tsis zoo, yog li kom ua tiav qhovsuab nrov-tshem tawm cov nyhuvCov. Thaum ob yoj nthwv dej lossis nthwv dej ncig ua ke, cov khoom tsis sib haum ntawm ob txoj kev nthwv dej yuav yog superimitosed tseem yuav tau ntxiv. Thaum nyob rau hauv lub ncov thiab hav, qhov kev co amplitude ntawm lub xeev superposition yuav raug muab tso tseg. Adas lub suab nrov hle tawm ntawm lub taub hau tau thov cov suab nrov nquag tshem tawm cov thev naus laus zis.
Ntawm lub suab nrov ncua kev tsoos taub hau lossis cov suab nrov pheej yig Qee tus neeg yuav xav tias nws yog dab tsi rau. Qhov no yog siv los sau cov suab sab nraud. Tom qab lub suab sab nraud yog sau, tus txheej txheem hauv lub pob ntseg yuav tsim cov suab nrov los tiv thaiv suab nrov rau cov suab nrov.
Thaum kawg, cov suab tawm suab thiab lub suab ua si hauv pob ntseg tau kis ua ke, kom peb tsis hnov cov suab sab nraud. Nws yog hu ua lub suab nrov ncua tseg vim tias nws tuaj yeem tsim kev tsim txom txawm tias yuav xam cov suab ntxias tiv thaiv tawm tsam.
