Kev tshawb fawb qhia tau hais tias ib puag ncig uas muaj suab meej meej tuaj yeem ua rau cov tub ntxhais kawm txoj kev kawm zoo dua 30% thiab kev koom tes hauv chav kawm nce 40%.

Hauv cov chav kawm ib txwm muaj, cov tub ntxhais kawm nyob rau hauv kab tom qab feem ntau tsis nco qab cov ntsiab lus tseem ceeb vim yog qhov tsis pom kev ntawm cov xib fwb, uas tau dhau los ua ib qho kev cuam tshuam zais cia uas cuam tshuam rau kev ncaj ncees ntawm kev kawm. Nrog rau kev txhim kho ntawm cov ntaub ntawv kev kawm, lub kaw lus suab zoo faib tawm tau dhau los ua tus qauv hauv cov chav kawm ntse, ua rau txhua tus tub ntxhais kawm txaus siab rau kev mloog sib npaug los ntawm cov cuab yeej siv thev naus laus zis.

Qhov zoo tshaj plaws ntawm lub tshuab suab faib tawm yog nws lub peev xwm tswj lub suab kom meej. Los ntawm kev faib ntau lub tso suab sib npaug thoob plaws lub qab nthab hauv chav kawm, nws ua tiav kev faib lub zog suab sib npaug, ua kom cov tub ntxhais kawm hauv ob kab pem hauv ntej thiab tom qab tuaj yeem hnov ​​​​​​cov ntsiab lus qhia meej thiab sib npaug. Qhov kev tsim no daws tau qhov teeb meem suab tsis sib npaug uas feem ntau pom hauv cov tshuab ib lub tso suab ib txwm muaj, qhov twg kab pem hauv ntej muaj suab nrov heev thaum kab tom qab nyuaj rau hnov ​​​​​​lus meej.

Lub tshuab ua kom lub suab nrov ua lub luag haujlwm tseem ceeb hauv kev ua kom lub suab zoo. Lub tshuab ua kom lub suab nrov digital uas tsim tshwj xeeb rau kev kawm muaj qhov sib piv ntawm lub teeb liab thiab lub suab nrov thiab cov yam ntxwv tsis muaj kev cuam tshuam, ua kom cov lus ntawm cov xib fwb tseem yog qhov tseeb thaum lub sijhawm ua kom lub suab nrov. Tsis tas li ntawd, lub tshuab ua kom lub suab nrov yuav tsum muaj peev xwm tswj tau ntau txoj kev ywj pheej kom ua rau muaj kev hloov kho qhov ntim kom raug rau ntau qhov chaw qhia ntawv.

Lub tshuab ua suab ntse yog ib rab riam phom zais cia rau kev txhim kho kev hais lus kom meej. Nws tuaj yeem ua kom tus xib fwb lub suab zoo dua hauv lub sijhawm tiag tiag, txhawb cov zaus tseem ceeb, thiab txo cov suab nrov hauv chav kawm. Tshwj xeeb tshaj yog nyob rau hauv cov chav kawm loj, lub tshuab ua haujlwm tswj kev tawm tswv yim tsis siv neeg tshem tawm cov suab quaj, tso cai rau cov xib fwb txav mus los tau yooj yim thaum lub sijhawm qhia ntawv yam tsis txhawj txog teeb meem suab.

Kev tsim lub microphone system yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm kev sib tham qhia ntawv. Cov microphones wireless pub cov xib fwb tsis tas yuav tuav cov khoom siv, ua rau lawv sau ntawv rau ntawm lub blackboard thiab siv cov khoom siv qhia ntawv tau yooj yim. Cov microphones uas muaj kev taw qhia hauv cov chaw sib tham ntawm cov tub ntxhais kawm ntawv ntes tau txhua tus tub ntxhais kawm ntawv cov lus hais kom raug, ua kom ntseeg tau tias txhua lub tswv yim raug kaw cia kom meej thaum sib tham ua pab pawg. Cov khoom siv ntes suab zoo no muab lub hauv paus rau kev qhia ntawv sib tham hauv online.

Hauv kev xaus, lub kaw lus suab faib tawm ntawm cov chav kawm ntse yog qhov kev daws teeb meem dav dav uas koom ua ke cov suab nrov sib xws, kev tswj hwm lub amplifier ntse, kev ua kom raugtus processor, thiab kev khaws lub microphone kom meej. Nws tsis yog tsuas yog daws cov teeb meem kev hnov ​​​​​​lus hauv kev ncaj ncees ntawm kev kawm xwb tab sis kuj muab kev txhawb nqa kev txawj ntse rau cov qauv kev qhia tshiab xws li kev qhia sib tham thiab kev koom tes hauv chaw deb. Hauv kev thawb rau kev kawm niaj hnub no, kev nqis peev rau kev tsim cov tshuab suab hauv chav kawm zoo ua lub luag haujlwm tseem ceeb rau kev kawm zoo thiab yog ib kauj ruam ua tau zoo rau kev ua tiav lub hom phiaj ntawm "kev ua kom txhua tus menyuam tuaj yeem txaus siab rau kev kawm zoo."
