Hauv suab reinforcement system, yog tias lub ntim ntawm lub microphone tau nce ntau, lub suab ntawm tus hais lus yuav raug xa mus rau lub suab nrov los ntawm lub microphone. Qhov tshwm sim no yog acoustic tawm tswv yim. Lub neej ntawmacoustic tswv yimtsis tsuas yog rhuav tshem lub suab zoo, tab sis kuj txwv qhov nthuav dav ntawm lub suab microphone, kom lub suab khaws los ntawm lub microphone tsis tuaj yeem rov ua dua zoo; qhov sib sib zog nqus acoustic tawm tswv yim tseem yuav ua rau lub teeb liab muaj zog heev, yog li hlawv lub hwj chim amplifier los yog hais lus (feem ntau yog hlawv.hais lus tweeter), ua rau poob. Yog li ntawd, thaum lub suab tawm tswv yim tshwm sim tshwm sim hauv lub suab txhawb zog, peb yuav tsum nrhiav txoj hauv kev los txwv nws, txwv tsis pub, nws yuav ua rau muaj kev puas tsuaj tsis kawg.
Dab tsi yog vim li cas rau acoustic tawm tswv yim?
Muaj ntau qhov laj thawj rau kev tawm tswv yim acoustic, qhov tseem ceeb tshaj plaws yog qhov tsim tsis tsim nyog ntawm lub suab nrov sab hauv tsev, ua raws li kev teeb tsa tsis tsim nyog ntawm cov neeg hais lus, thiab qhov tsis zoo debugging ntawm cov khoom siv suab thiabaudio system.Tshwj xeeb, nws suav nrog plaub yam hauv qab no:
(1) Cov microphoneyog muab tso ncaj qha rau hauv qhov hluav taws xob cheeb tsam ntawm lubtus hais lus, thiab nws axis yog ncaj qha mus raws li tus neeg hais lus.
(2) Lub suab cuam tshuam qhov tshwm sim yog qhov hnyav nyob rau hauv lub suab txhawb zog ib puag ncig, thiab ib puag ncig thiab qab nthab tsis tau dai kom zoo nkauj nrog cov khoom siv suab nrov.
(3) Kev sib txuam tsis zoo ntawm cov khoom siv suab, kev xav txog lub teeb liab loj, kev sib txuas virtual ntawm cov kab sib txuas, thiab cov ntsiab lus tiv tauj thaum lub suab teeb liab ntws los ntawm.
(4) Qee cov khoom siv suab nyob rau hauv lub xeev ua haujlwm tseem ceeb, thiab oscillation tshwm sim thaum lub suab teeb liab loj.
Kev tawm tswv yim acoustic yog qhov teeb meem nyuaj tshaj plaws hauv kev siv lub suab ntxiv. Txawm hais tias nws yog nyob rau hauv theaters, venues los yog seev cev halls, thaum lub acoustic tawm tswv yim tshwm sim, nws yuav tsis tsuas ua puas lub cev ua hauj lwm lub xeev ntawm tag nrho cov suab system, rhuav tshem lub suab zoo, tab sis kuj yuav ua rau puas.kev sib tham, kev ua haujlwm zoo. Yog li ntawd, kev tawm tsam ntawm acoustic tawm tswv yim yog qhov teeb meem tseem ceeb heev uas yuav tsum tau them sai sai rau hauv cov txheej txheem ntawm kev debugging thiab kev siv lub suab txhawb zog. Cov neeg ua haujlwm suab yuav tsum nkag siab txog cov lus tawm tswv yim acoustic thiab nrhiav txoj hauv kev zoo dua los zam lossis txo qhov kev quaj nrov los ntawm acoustic tswv yim.
