Sib ntaus cov chav phem-cov qauv siv microphone
Dab tsi yog "chav phem?" Cov chav phem yog cov chaw uas lub koomhaum ua lag luam yog tus muaj kev cuam tshuam los ntawm qhov chaw nws tus kheej. Qhov no yuav yog vim tsis muaj teeb pom kev zoo, tsis xis nyob, kev tswj tsis zoo, kev tsis ncaj ncees hauv chav tsev, lossis tsev tsis muaj vaj tse.
Tiam sis peb cov neeg hauv AV zej zos feem ntau ntsib cov chav nyob qhov twg qhov teeb meem loj tshaj plaws rau kev sib txuas lus yog qhov chaw ntawm cov khoom siv hauv tsev kawm ntawv. Feem ntau cov acoustics yog ib qho kev sib tw thaum cov hniav ua cim ntau lub suab los yog qhov chaw resonates ntev. Qee zaum qhov teeb meem kev phem tshaj plaws yog lub HVAC system uas yog poob rau kev sib txuas lus thiab ntxiv ib lub suab nrov nrov rau lub suab ntawm lub microphone uas yuav pub suab nrov lub suab nrov nrov thiab cov suab paj nruag kawg rau kev sib tham video thiab audio.
Qee lub sij hawm cov neeg tsis xav txog lawv chav yuav yog "phem" vim tias lawv yeej siv rau nws lub zog. Tab sis txawm tias koj pom nws los yog tsis, chav tsev noj ib tus xov tooj hu rau koj pab neeg. Qee chav no yog qhov qhia tau yooj yim thiab nkag siab tias nws tsis yooj yim to taub kev hais lus nruab nrab ntawm ob tug neeg nyob rau sab lus ntawm lub rooj sib tham ("Aquarium" chav zoo li ua ib tus kws kos duab ntawm tus kws kos duab). Phem chav ua hauj lwm ntau nyuaj; ob qho tib si rau tus saib xyuas thiab tus mloog. Ntxiv cov kev sib tw ntawm BYOD video / suab sib tham, thiab cov chav phem noj kom cov neeg ua haujlwm zog thiab ua kom tiav tej yaam num ntau kim los qeeb lawv. Thiab hnub no ntau thiab ntau dua ntiag tug, cov chav tsev, thiab cov chaw noj mov yeej tsis txaus siab ua cov chav sablaj.
Qee lub sij hawm cov neeg yuav pab peb kom "kho" chav tsev nrog lub tshuab hluav taws xob-AV; tab sis qhov no yuav tsum yog txoj kev thib ob tom qab txhua yam uas tsim nyog ua tau los kho cov hauv paus teeb meem ntawm chav teeb meem tau hais. Vim li cas tus neeg mob tsis xav kho lub chav ntawd?
Ib qho yog vim li no nyob rau hauv feem ntau cov koom haum, tsis muaj leej twg "muaj" lub suab paj nruag ntawm lub tsev. Yog tias tus thawj tsim lub tsev tsis tsim kom muaj kev siv acoustic, qhov ntxiv ntawm cov kev kho mob acoustic tsis tshua tau nyob rau hauv txhua fab kev tswj hwm. Puas yog IT department "tus kheej" acoustics? Ua cov neeg siv qhov kawg 'cov koom haum muaj nws? Yuav ua li cas rau pawg neeg tswj haujlwm? Nws yuav ua rau kev kho mob acoustic yuav tsis yog qhov khoom tshwj xeeb tshwj tsis yog tias koj lossis lwm tus neeg paub lwm tus tau txais kev txhawj xeeb ntawm ib tus neeg muaj npe nyob hauv lub koom haum uas paub txog qhov teeb meem ntawm qhov teeb meem thiab tus nqi ntawm kev daws cov hauv paus ua. Hmoov tsis qhov no tsis tshwm sim ntau txaus.
Yog li, peb yuav ua licas? Peb yuav tsum nco ntsoov txheeb xyuas lub hauv paus thiab qhov cuam tshuam ntawm cov teeb meem acoustic nrog chav. Qhov no ob leeg muab tus neeg muaj lub cib fim los hloov cov kev xav tau, thiab, qhov tseem ceeb tshaj plaws, hais txog cov kev txwv ntawm peb cov txheej txheem hluav taws xob ua tau los daws qhov teeb meem hauv chav-qhov teeb meem. Tus neeg mob yuav tsum nkag siab tias lawv yuav tsis tau tag nrho cov nyiaj ntawm siv nyiaj txawm tias qhov zoo tshaj plaws nruab suab yog hais tias chav tsev tseem "phem" qhwv ntsej muag.
Yog li cas peb ua li cas yog tias tus neeg mob yuav tsis txhim kho hauv paus ua? Muaj qee qhov kev muaj peev xwm.
Microphones, txawm tias wired lossis wireless, muaj cov yam ntxwv txawv. Ib qho tseem ceeb tshaj plaws nrog lub tshuab ua kom siv lub tshuab ua kom haum thiab siv nyob rau hauv qhov chaw ua si yuav tau ua nrog ntau npaum li cas ntawm lub suab lus sib xyaw nrog cov "chav kawm." Los ntawm cov ntsiab lus ntawm chav kawm, peb txhais tau hais tias qhov kev xav, nrov, thiab qhov chaw nyob ntawm qhov chaw tus presenter nyob rau hauv. Obviously nyob rau hauv ib qho chaw "phem" peb xav tau ntau lub suab lus thiab tsawg chav kawm.
Qhov yoojyim txoj hauv kev ua kom lub suab tau zoo tshaj plaws yog qhov los ntawm tus neeg saib xyuas lub qhov ncauj ze ntawm lub microphone. Raws li qhov ntxig-square-law thiab kev lag luam PAG / NAG lub laij zauv; ib tug thawj coj ntawm ib qho chaw ze ntawm lub mic tau ze plaub zaug ntawm lub suab lus ntawm ob tus neeg sab nraud (deb tshaj tawm lub suab ntawm lub suab yog pom li 1/4 ntawm tus presenter lub suab zog). Yog tias peb saib ntau hom kabmob microphones (wired lossis wireless) Handhelds, Lavalier / Headsets, thiab Gooseneck microphone designs yuav muab tus neeg tuaj yeem saib zoo tshaj plaws ntawm kev hais lus nyob ze ntawm lub microphone capsule kom lub suab mus rau qhov chaw siab siab. Hmoov tsis, cov neeg tuaj koom hauv ntau lub koom haum tsis raug cob qhia txog kev siv lub microphone zoo li cas. Yog li txawm nrog cov hom microphone, qhov zoo tshaj plaws piv tsis tau yog tias tus saib xyuas tsis siv cov tswv yim siv microphone. Muaj ntau cov dej num loj loj muaj xws li kev rau cov neeg siv kev cob qhia; Txawm li cas los xij, koj yuav tsis tau txais feem ntau ntawm cov koom haum (lossis nws cov qhua) rau koj chav kawm.
Cov tswv yim zoo tshaj plaws uas koj cov neeg pabcuam AV tuaj yeem siv yog ua tau zoo tshaj plaws rau lub sijhawm. Qhov no txhais ua ntau txoj kev coj ua:
Yog hais tias cov neeg tuaj zaum tau zaum ntawm rooj, Gooseneck mics yog superior li lawv tau txais lub microphone keeb ze cov neeg tuaj sab nraud. Tsis txhob siv cov microphones ciam rau hauv ib chav "tsis zoo" vim hais tias chav tsis muaj teeb meem yuav tsum muaj ntau qhov teeb meem-ciam teb sau tag nrho cov suab ntawm chav hauv theem (additively) ntawm cov ciam teb uas lawv tso.
Yog cov neeg tuaj yeem yog ncig ntawm qhov chaw, muab lawv lub pob ntseg / lavalier los yog cov microphones cov kev coj ua. Hopefully ib tug neeg yuav tau txais ib lub caij nyoog rau cov xibfwb qhia cov neeg siv los tuav lub mic capsule 4 txog 8 ntiv tes tawm ntawm lawv lub qhov ncauj hauv qhov chaw nyuaj. Ib lub tswv yim yog los ua cov ntawv "kev pabcuam" laminated rau kev siv cov khoom siv thiab lub lav thiab khaws cia rau saum cov lecterns thiab qhov chaw khaws cia rau kev siv.
Gooseneck mics kuj ua haujlwm zoo rau lecterns-yog hais tias tus neeg saib xyuas tseem nyob hauv qhov chaw, los yog "hauv mic." Yog tias tsis yog, lawv yuav tsum siv cov Kev Kuaj Rau Me Nyuam los yog Cov Nqis Handheld.
Chav DSP uas txwv cov mics qhib thiab cov ntxaij lim dej (thiab lwm qhov chaw txias) thiab kuj yuav pab tau ntxiv nrog rau cov tswvyim mic nyob rau saum toj no.
Feem ntau ntawm koj nyeem qhov no twb paub txog peb cov kev cov nyom nrog cov chav tsis zoo. Tab sis tej zaum koj tuaj yeem xa qhov no mus rau ib tug neeg ua hauj lwm; los sis txawm tias tus neeg xav tau xav paub tias txawm tias AV tshaj plaws hauv AV yeej tsis muaj peev xwm kov yeej kev foom phem ntawm "Chaav Phem."
