Dab tsi yog microphone polar qauv?
Microphone polar patterns piav qhia txog txoj hauv kev uas lub microphone lub ntsiab lus khaws lub suab los ntawm qhov chaw nyob ib puag ncig nws.Feem ntau muaj peb hom polar qauv ntawm lub microphone.Lawv yog cardioid, omnidirectional, thiab daim duab-8, tseem hu ua bidirectional.
Cia peb nkag mus rau hauv txhua yam ntawm cov no kom ntxaws ntxiv.
Raws li ib tug thawj coj ntawm microphone manufacturers, peb muab ntau yam microphones nrog txawv polar qauv.
Thawj hom: cardioid
Microphones nrog cov qauv cardioid polar tuaj tos lub suab zoo hauv lub plawv zoo li tus qauv nyob rau pem hauv ntej ntawm lub microphone.Ob sab ntawm lub microphone tsis tshua muaj kev nkag siab tab sis tseem yuav tuaj yeem tuaj yeem siv tau lub suab ntawm qhov ze dua, thaum lub nraub qaum ntawm lub microphone yog tag nrho ntawm qhov ntau.Lub cardioid microphone muaj txiaj ntsig zoo hauv kev cais cov suab tsis xav tau thiab tsom mus rau qhov tseem ceeb - qhov no yog qhov tsim nyog rau cov theem nrov.Txawm li cas los xij, kuj ua rau nws muaj kev cuam tshuam ntau dua rau cov lus tawm tswv yim piv rau lwm cov polar patterned microphones.
bkd-11 yog ib qho ntawm peb lub microphones muag zoo tshaj plaws uas nws tus qauv polar yog cardioid.Hauv qab no yog daim duab.
Hom thib ob: omnidirectional
Microphones nrog omnidirectional polar qauv tuaj tos lub suab sib npaug thoob plaws hauv 360-degree qhov chaw.Qhov ntau ntawm qhov chaw zoo li no tuaj yeem sib txawv ntawm lub microphone mus rau microphone.Tab sis cov duab ntawm tus qauv yuav tuav qhov tseeb thiab lub suab zoo yuav nyob twj ywm ntawm txhua lub kaum sab xis thaum siv lub microphone omnidirectional.Lub microphone nrog omnidirectional polar qauv tsis tas yuav tsum tau muab tso rau los yog qhia ib txoj hauv kev los ntes suab vim nws yog tsim los ntes ob qho tib si pub thiab lub suab ambient yog li ua rau nws muaj txiaj ntsig zoo tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm lavalier microphones.A downside rau Omni, txawm li cas los xij, yog tias lawv tsis tuaj yeem tsom mus deb ntawm qhov tsis xav tau xws li Public Chaw nyob hais lus thiab qhov no yuav ua rau muaj kev tawm tswv yim.
BKM-10 yog ib qho ntawm peb lub microphone zoom rau cov rooj sib tham.
Thib peb: bidirectional
Tus qauv bidirectional polar tseem hu ua tus qauv-8 polar qauv vim tias cov duab ntawm qhov chaw khaws khoom tsim cov qauv ntawm daim duab-8.Lub microphone bidirectional kaw suab ncaj qha rau pem hauv ntej thiab ncaj qha tom qab lub tshuaj ntsiav yam tsis tau khaws suab los ntawm ob sab.
