Lawv qhov sib txawv tseem ceeb nyob hauv nruab nrab ntawm kev nthuav tawm ntawm kev vibrations. Hauv thawj kis, cov no yog cov khib nyiab, thiab hauv qhov thib ob, cua.
Vim tias cov teebmeem acoustic no tuaj yeem tsis yog qhov tsis zoo rau kev nkag siab xwb, tab sis kuj txaus ntshai rau tib neeg kev noj qab haus huv, yuav tsum tau saib xyuas kom ntseeg tau tias muaj lub suab rwb thaiv tsev txaus ntawm chav tsev nyob thiab lwm qhov chaw uas tus neeg nyob.
Ib qho ntawm kev siv ntau tshaj plaws ntawm kev tiv thaiv suab nrov yog huab cua. Nws cov yam ntxwv thiab cov txiaj ntsig suav nrog txhua qhov chawkev tso kawm thiab kev nkag siab siab.
Yog li, ntau yam qauv thiab cov khoom siv hauv tsev uas muaj cov chaw kaw uas muaj cov cua txias ua rau lub suab nrov uas muaj kev tiv thaiv zoo. Lub xub ntiag ntawm qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
Thiab, cov khoom siv suab nrov muab lub sijhawm rau cais cov chav nrog lub suab nrov ntawm cov chaw nyob ib sab. Cov chaw zoo li no suav nrog xinemas, khw thiab chaw lom zem, ntau lub tsev ua kis las thiab chaw ua haujlwm, nrog rau qhov chaw ua haujlwm. Nrog rau qhov chaw raug thiab kev teeb tsa ntawm kev tiv thaiv zoo, kev txo qis hauv lub zog ntawm kev vibrations thiab nthwv dej tuaj yeem ua tiav, uas yuav txo qhov cuam tshuam lossis tshem tawm cov suab nrov ntau dhau.
Cov khoom siv suab nrov yuav tsum muaj cov yam ntxwv xav tau thiab ua tau raws li qhov xav tau nruj. Tag nrho cov no yog txiav txim los ntawm qhov ntsuas qhov zoo, piv txwv li, tus nqi ntawm lub suab nqus, qhov ntau ntawm 0 txog 1.
Raws li kev tsim kho pom, cov ntaub ntawv muaj peev xwm dhau los ntawm huab cua, nrog qhib qhov hws, muaj qhov zoo tshaj plaws suab nqus coefficient. Cov no suav nrog iav thiab ntxhia ntaub plaub, ntau yam kev xav tau, thiab lwm yam.
Tsi,txhua cov khoom siv suab nrov yuav tsum ua tau raws li qhov xav tau ntawm ib puag ncig thiab hluav taws kub. Qhov no yog vim qhov tseeb tias feem ntau cov tshuaj no yuav siv rau kev ua haujlwm sab hauv. Yog li ntawd, lawv yuav tsum muaj cov khoom zoo xws li kev yooj yim ntawm kev siv, durability, noo noo tsis kam thiab zoo nkauj.
Yog li, cov khoom siv suab nrov yuav tsum tau siv tag nrho txawm tias nyob rau theem pib ntawm kev tsim kho, cais thaj chaw ntawm cov suab nrov, nrog rau kev muab cov suab pov thawj ntawm thaj chaw los ntawm kev cuam tshuam sab nraud.
