Qhov tseeb Txog kev tawm tswv yim hauv suab conferencing microphone
Thaum lub sij hawm niaj zaus blamed ntawm lub microphone, qhov tseeb yog tias cov microphones yog cov khoom siv uas tsis tuaj yeem ncav tsis cuag thiab "ua" lub suab. Tiam sis, cov tswv yim acoustic yog qhov system raws. Nws yog tshwm sim los ntawm kev sib xyaw ntawm cov khoom, nrog rau cov chav tsev nrov thiab qib siab, ntxiv rau
qhov taw qhia, kev coj ua, thiab kev sib kis ntawm cov microphones thiab cov lus nrov nrov, tag nrho cov uas tuaj yeem ua rau cov neeg pluag nce ua-tawm tswv yim.
Phem microphone feem ntau tiv thaiv lub suab kaw suab ntawm kev ua tau zoo. Kev cob qhia cov neeg tuaj saib ntawm cov txheej txheem mic yog ib qho tseem ceeb raws li chav tsev zoo nkauj. To taub hais tias lub tshav xov tooj nrov ua rau lub peev xwm ua haujlwm yog qhov tseem ceeb heev rau kev nrhiav kom tau qhov kev tawm tswv yim.
Tsim lub suab zoo uas tsis muaj kev tawm tswv yim yog qhov kev ntsuas ntawm qhov ua tau zoo tshaj plaws hauv chav tsev Cov Kev Siv Tau Txais (Acoustic Gain) (nrov li cas nws tuaj yeem tsis muaj kev tawm tswv yim) thiab Xav Tau Kev Tshawb Tau Acoustic (qhov nyiaj nce ntxiv kom txhua tus tuaj yeem hnov). Thaum lub zauv ntawm PAG / NAG tseem ceeb hauv chav tsim, paub txog cov kev coj ua zoo tshaj plaws hauv kev tso kawm thiab kev siv lub suab kaw lus yuav tsum txaus siv rau cov kev siv tam sim no. Rau cov lus qhia ntxiv, saib ntawm cov sab nraud ntawm Tswv yim Fixes.
Qhov ntau reverberant chav tsev, qhov ntau dua nws yog rau cov tswv yim tshwm sim. Feem ntau cov kev cai reverberant feem ntau tau nce kev txawj ntse, uas ua rau cov neeg siv xav tig lub ntim hauv kev sib zog kom hnov ntau yam meej. Zoo li tawm tswv yim xwb, nws yog qhov voj voog. Zoo hmoo, me ntsis kev paub yog txhua yam nws yuav siv sij hawm los tswj nws.
