Lub suab nrov ua rau muaj kev cuam tshuam rau ntau yam kev lag luam thiab lub neej niaj hnub
Feem ntau, peb feem ntau xa mus rau lub suab tsis xav ua suab nrov, xws li suab nrov ib puag ncig, suab nrov ntawm kev khiav tsheb, thiab lwm yam. Lub suab piano yog suab paj nruag, tab sis rau cov neeg uas kawm lossis pw tsaug zog, nws dhau los ua suab nrov.
Raws li cov suab sib txawv, suab nrov tuaj yeem muab faib ua suab nrov, suab nrov aerodynamic, thiab suab nrov electromagnetic. Mechanical suab nrov yog tsim los ntawm cov khoom vibration. Thaum lub tshuab ua haujlwm, vim muaj kev cuam tshuam rau txhua yam, kev sib txhuam, kev sib hloov ntawm lub tshuab ua haujlwm, thiab lub zog tsis sib xws thaum lub sijhawm ua haujlwm, cov hlau phaj, lub zog, bearings, thiab lwm yam ntawm cov tshuab vibrate, yog li radiating mechanical suab nrov, xws li suab nrov tsim los ntawm cov cuab yeej siv tshuab, weaving. cov cav tov, pob zeb, thiab lwm yam. Thaum cov pa roj thiab cov pa roj, nrog rau cov roj thiab lwm yam khoom (khoom los yog kua) txav mus rau hauv cov kev sib txheeb ntawm cov suab nrov nrawm, cov pa cuam tshuam los ntawm viscosity ua rau lub suab nrov aerodynamic, xws li ntau hom kiv cua kom tsawg thiab tso pa tawm. suab nrov, dav hlau dav hlau hneev taw, sab hauv combustion engine pa, thiab roj cia tank tso suab nrov. Kev tawg ua rau nrawm nrawm ntawm huab cua ib puag ncig kuj yog lub suab nrov aerodynamic. Electromagnetic nrov yog hais txog lub suab nrov uas tsim los ntawm cov khoom siv hluav taws xob vim yog qhov sib nqus ntawm qhov sib nqus thiab cov magnetostriction, xws li cov suab nrov tsim los ntawm cov transformers.
Lub nroog ib puag ncig lub suab nrov ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb suab nrov, feem ntau yog los ntawm cov suab nrov nrov, suab nrov hauv kev lag luam, suab nrov ntawm kev tsim kho, thiab suab nrov hauv lub neej. Vim tias muaj ntau lub tsheb tsav thiab kev siv dav hlau supersonic hauv nroog, lub suab nrov uas tsim los ntawm cov tsheb thauj mus los (xws li tsheb, tsheb laij teb, tsheb ciav hlau, dav hlau, thiab lwm yam) tau dhau los ua ib qho ntawm cov pa phem tseem ceeb ntawm lub nroog ib puag ncig lub suab nrov. . Kev lag luam suab nrov tsis tsuas yog cuam tshuam ncaj qha rau cov neeg ua haujlwm tsim khoom, tab sis tseem cuam tshuam rau cov neeg nyob ze. Nyob rau hauv kev lag luam suab nrov, lub suab nrov ntawm textile mills ranges ntawm 90 mus rau 106dB, thaum nyob rau hauv kev lag luam tshuab, nws txawv ntawm 80 mus rau 120dB rau cov pob zeb loj thiab cov tshuab tshuab, tshaj 130dB. Kev lag luam suab nrov yog lub ntsiab ua rau lub suab nrov induced hnov tsis hnov qab. Lub suab nrov ntawm kev tsim kho yog tshwm sim los ntawm kev siv ntau yam kev tsim kho tshuab xws li pawg tsav tsheb, cov khoom sib tov, thiab cov tshuab txiav ntawm cov chaw tsim kho. Kev ua si hauv zej zog thiab tsev neeg lub suab nrov kuj tseem muaj, xws li kev siv ntau dhau ntawm cov neeg hais lus siab rau kev tshaj tawm, uas tuaj yeem tsim cov suab nrov nrov. Hauv kev ua neej nyob, kev siv xov tooj cua tsis raug, cov kaw lus kaw, thiab TV kuj tuaj yeem dhau los ua lub suab nrov uas cuam tshuam rau cov neeg nyob ze hauv ntau qhov xwm txheej. Cov khoom siv hauv tsev xws li cov kiv cua hluav taws xob, lub tub yees, thiab lub tshuab ntxhua khaub ncaws, yog tias tsim thiab tsim khoom tsis raug lossis siv tsis raug, kuj tuaj yeem ua suab nrov.
