Qee qhov kev nkag siab zoo txog kev xaiv suab qib meter:
Muaj qib thib ib thiab qib thib ob ntawm lub suab ntsuas ntsuas. Ntau tus neeg tsis to taub tias nws txhais li cas. Yuav kom suav nws, qhov tseeb yog qhov sib txawv. Qhov tseeb qib thawj yog 0.7 decibels, thaum qib thib ob yog 1 decibels. Qhov sib txawv tsis loj, tab sis qhov tseem ceeb ntawm lub teb chaws tus qauv, Tau kawg, thawj theem suab ntsuas ntsuas yog tus neeg sawv cev, yog li rau cov neeg sab nrauv lossis tsoomfwv cov koom haum, ncaj qha mus yuav thawj theem suab ntsuas ntsuas. Thib ob, raws li kev ua haujlwm, muaj qhov zoo tib yam, ib txwm, mem tes, thiab spectrum. Yuav ua li cas paub qhov txawv thiab pom zoo qhov no? Ordinary Qhov instantaneous ib qho yog kev nyeem ncaj qha, thiab ib qho tseem ceeb muaj qhov nruab nrab ntawm ib lub sijhawm. Lub mem tes yog qhov yooj yim dua. Koj tuaj yeem nkag siab tias muaj lub suab nrov nrog ntau zaus hauv ib lub sijhawm. Cov spectrum tuaj yeem nkag siab tias muaj qhov nkhaus ib txwm muaj. Daim duab yog rau kev tshawb fawb, kev pom zoo yuav tsum muaj nyob rau hauv kev xaiv, cov chav sib txawv, cov neeg sib txawv, cov kev lag luam sib txawv thiab cov chaw sib txawv siv cov cuab yeej sib txawv, xws li cov neeg thib peb siv Aiwa qib ib, thee mines siv tawg-pov thawj mine kev nyab xeeb thiab lwm yam. ntawm.
