Nyob rau hauv lub lub kaw lus txhawb zog suab, yog tias lub suab ntawm lub microphone nce siab heev, lub suab los ntawm lub hais lus yuav raug xa mus rau lub suab quaj uas los ntawm lub microphone. Qhov xwm txheej no yog kev tawm tswv yim acoustic. Lub neej ntawmkev tawm tswv yim acoustictsis yog tsuas yog ua rau lub suab zoo xwb, tab sis kuj txwv qhov ntim ntawm lub microphone suab, yog li ntawd lub suab uas lub microphone khaws tsis tuaj yeem rov ua dua zoo; qhov kev tawm tswv yim tob tob kuj tseem yuav ua rau lub teeb liab ntawm lub kaw lus muaj zog dhau, yog li hlawv lub zog amplifier lossis lub tso suab (feem ntau hlawvlub tshuab hais lus tweeter), ua rau poob. Yog li ntawd, thaum muaj qhov tshwm sim suab rov qab los hauv lub kaw lus txhawb nqa suab, peb yuav tsum nrhiav txoj hauv kev los tiv thaiv nws, txwv tsis pub, nws yuav ua rau muaj kev puas tsuaj tsis kawg.
Dab tsi yog vim li cas rau cov lus teb acoustic?
Muaj ntau yam ua rau muaj kev tawm tswv yim acoustic, qhov tseem ceeb tshaj plaws yog qhov tsim tsis tsim nyog ntawm qhov chaw txhawb nqa suab hauv tsev, ua raws li qhov kev teeb tsa tsis tsim nyog ntawm cov neeg hais lus, thiab qhov kev debugging tsis zoo ntawm cov khoom siv suab thiablub tshuab suab.Tshwj xeeb, nws suav nrog plaub yam hauv qab no:
(1) Lub lub microphoneyog muab tso ncaj qha rau hauv thaj chaw hluav taws xob ntawmtus neeg hais lus, thiab nws cov axis yog ncaj qha mus phim nrog lub hais lus.
(2) Qhov xwm txheej ntawm kev cuam tshuam suab yog qhov loj heev hauv qhov chaw txhawb nqa suab, thiab ib puag ncig thiab qab nthab tsis tau dai kom zoo nkauj nrog cov ntaub ntawv nqus suab.
(3) Kev sib phim tsis raug ntawm cov khoom siv suab, kev cuam tshuam loj heev ntawm lub teeb liab, kev sib txuas virtual ntawm cov kab sib txuas, thiab cov ntsiab lus sib cuag thaum lub suab ntws los.
(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.
Cov lus teb acoustic yog qhov teeb meem nyuaj tshaj plaws hauv kev txhawb nqa suab hauv tsev. Txawm hais tias nws yog nyob rau hauv chaw ua yeeb yam, chaw ua si lossis chaw seev cev, thaum cov lus teb acoustic tshwm sim, nws yuav tsis tsuas yog rhuav tshem lub xeev ua haujlwm ib txwm ntawm tag nrho lub suab, rhuav tshem lub suab zoo, tab sis kuj rhuav tshem lublub rooj sib tham, kev ua tau zoo. Yog li ntawd, kev tswj hwm cov lus teb acoustic 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 cov txheej txheem txhawb nqa suab. Cov neeg ua haujlwm suab yuav tsum nkag siab txog cov lus teb acoustic thiab nrhiav txoj hauv kev zoo dua los zam lossis txo qhov kev quaj los ntawm kev tawm tswv yim acoustic.
