Configuration thiab tuning ntawm pej xeem chaw nyob systems

Discernment ntawm kev xav tau nyob rau hauv lub suab

Ua ntej kev teeb tsa, nws tsim nyog qhia meej txog cov xwm txheej uas peb lub suab yuav ua haujlwm thiab qhov kev daws teeb meem twg yog qhov zoo tshaj plaws los xaiv. Ib qho ntawm feem ntau siv lub suab txhawb zog yog cov kab ke, uas yog raws li cov qauv modular, tso cai rau kev nthuav dav ntawm qhov system nrog cov ntsiab lus ntxiv. Thaum txiav txim siab txog qhov kev daws teeb meem zoo li no, nws yuav tsum tau ua raws li cov xwm txheej uas peb npaj siab tshaj tawm thiab qhov chaw. Peb yuav teeb tsa lub suab sib txawv yog tias peb xav tshaj tawm kev sib tham sab nraum zoov, thiab sib txawv thaum peb yuav tshaj tawm cov rooj sib tham txog kev tshawb fawb hauv tsev kawm qib siab. Tseem muaj lwm yam kev txwv yuav tsum tau muab lub suab rau cov xwm txheej tshwj xeeb, xws li kab tshoob kev kos, rooj noj mov, thiab lwm yam. Tau kawg, qhov teeb meem tseem ceeb yog qhov loj me, piv txwv li qhov ntau yam uas lub suab kaw lus yuav muab, kom lub suab kom meej meej audible. nyob txhua qhov chaw. Peb yuav muab lub suab rau lub gymnasium, lub tsev teev ntuj, thiab football chaw ntau pob nyob rau hauv ib txoj kev sib txawv.

Passive system los yog active

Lub suab nrov passive yog siv los ntawm lub tshuab hluav taws xob sab nraud thiab ua tsaug rau qhov kev daws teeb meem no peb tuaj yeem kho lub amplifier rau peb qhov kev nyiam, piv txwv li, kom tau txais lub suab tshwj xeeb, siv lub raj amplifier.

Lub suab nrov yog nruab nrog nws tus kheej lub zog thiab ntau thiab ntau dua xaiv vim tias peb tsis nyob ntawm lub tshuab hluav taws xob sab nraud, yog li thaum mus rau tog peb muaj ib lub nra tsawg.

Suab tshuab

Peb tuaj yeem paub qhov txawv ntawm peb lub suab nrov, txhua tus muaj ib daim ntawv thov sib txawv, thiab qhov kev xaiv tau hais los ntawm qhov chaw yuav tsum tau suab. Central system, uas yog siv rau suab, ntawm lwm tus, auditoriums, auditoriums thiab lecture halls. Cov khoom siv nrov nrov yog nyob rau hauv ib lub dav hlau ze ntawm qhov chaw ntawm qhov kev ua haujlwm tsis tu ncua, thiab lub ntsiab axes ntawm lub suab nrov nrov hluav taws xob hauv lub dav hlau kab rov tav yuav tsum tau qhia kwv yees li diagonally hauv chav. Qhov kev npaj no lav qhov sib koom ua ke ntawm qhov muag pom thiab acoustic impressions pom los ntawm tus neeg mloog.

Ib qho kev faib tawm uas cov neeg hais lus sib npaug sib npaug ntawm tag nrho qhov chaw tsis muaj suab nrov, yog li zam qhov kev hloov pauv loj hauv suab siv ntawm cov ntsiab lus sib txawv hauv chav. Feem ntau cov kab tau raug tshem tawm ntawm lub qab nthab thiab qhov kev npaj no feem ntau yog siv rau hauv chav ntev thiab qis.

Zone system nyob rau hauv uas cov neeg hais lus tau muab tso rau hauv ib cheeb tsam, uas tag nrho cheeb tsam tau muab faib, qhov twg txhua pab pawg neeg hais lus yog los nthuav ib cheeb tsam. Kev xaiv ncua sij hawm ncua sij hawm tsim nyog yog qhia ntawm ib pawg ntawm cov neeg hais lus nrov hauv thaj chaw. Xws li ib qho system feem ntau yog siv rau hauv qhov chaw qhib.

Suab system tuning method

Cov cuab yeej zoo yog lub hauv paus, tab sis kom ua kom zoo dua ntawm nws lub hwj chim thiab zoo, nws tsim nyog muaj kev paub txog nws cov kev teeb tsa, kev teeb tsa thiab tag nrho lwm cov ntsiab lus uas cuam tshuam rau qhov kawg tshwm sim. Nyob rau hauv lub era ntawm digitization, peb muaj cov cuab yeej tsim nyog ntawm peb qhov chaw pov tseg uas yuav qhia txog qhov chaw zoo tshaj plaws ntawm cov khoom siv suab. Nws yog feem ntau cov software ntsia ntawm peb lub laptop uas xa cov ntaub ntawv no rau peb. Txawm li cas los xij, txhawm rau ua kom siv tau zoo ntawm txoj kev no, cov ntsuas tus kheej yuav tsum tau nyeem kom raug. Qhov tseem ceeb tshaj plaws yog RTA, uas yog ib qho kev ntsuas ob sab uas nthuav tawm lub zog theem qhia hauv decibels lossis volts hauv ib qho kev sib tw tshwj xeeb. Kuj tseem muaj peb lub ntsuas ntsuas xws li TEF, SMAART, SIM, uas ntxiv rau tam sim no hloov pauv ntawm lub zog ntawm tus kheej zaus dhau sijhawm. Qhov sib txawv ntawm ntau lub tshuab yog tias RTA tsis suav nrog lub sijhawm dhau los, thiab peb lub ntsuas ntsuas yog raws li kev sib kis ceev FFT. Yog li ntawd, nws tsim nyog kawm ntxiv txog tus kheej cov ntsuas thiab ntsuas, yog li tsis yog koj tuaj yeem nyeem lawv kom raug, tab sis kuj tuaj yeem siv rau qhov chaw uas peb ntsuas thiab kho. Ib qho yuam kev hauv peb qhov kev ntsuas yuav yog qhov tsis raug ntawm qhov ntsuas microphone nws tus kheej. Ntawm no, ib yam nkaus, nws tsim nyog txheeb xyuas qhov twg xws li lub microphone yuav tsum nyob. Puas muaj tej yam teeb meem, kev xav ntawm phab ntsa, thiab lwm yam, distortions uas distort peb ntsuas. Nws kuj tseem tuaj yeem tshwm sim txawm tias qhov tsis txaus siab, peb tsis txaus siab rau qhov teeb tsa. Tom qab ntawd peb yuav tsum siv lub ntsuas ntsuas qhov zoo tshaj plaws uas yog lub cev hnov ​​lus.

Summation

Raws li koj tuaj yeem pom, qhov raug teeb tsa ntawm lub suab kaw lus yuav tsum tau coj mus rau hauv tus account ntau yam. Yog li ntawd, nws tsim nyog txheeb xyuas txhua qhov teeb meem zoo thiab coj mus rau hauv tus account uas muaj kev cuam tshuam ncaj qha rau lub zog thiab qhov zoo ntawm cov teeb liab kis. Thiab raws li nyob rau hauv ntau yam ntawm lub suab system thiab nws cov chaw, kuj nyob ntawm no, thaum lub sij hawm kawg tuning, peb yuav zaum yuav tau sim me ntsis kom nrhiav tau qhov chaw zoo rau peb cov khoom.
