Tawm tsam keeb kwm yav dhau los ntawm kev xav tau ntawm lub zog tsis tu ncua thiab nce kev tiv thaiv ib puag ncig, qhov tseem ceeb ntawm cov twj siv hluav taws xob uas ntsiag to tau dhau los ua qhov tseem ceeb. Raws li ib qho kev tshaj lij ntawm cov tshuab hluav taws xob tsim hluav taws xob hauv kev tswj lub suab nrov, nws tsis tsuas yog txuas ntxiv qhov zoo ntawm cov khoom siv hluav taws xob ib txwm siv hluav taws xob- muaj kev ntseeg siab, muaj peev xwm thauj khoom, thiab cov khoom siv hluav taws xob ywj pheej- tab sis kuj tseem daws cov ntawv thov lub hwj chim ntawm cov pa hauv cov cheeb tsam uas muaj neeg coob coob, kev ua haujlwm hmo ntuj, thiab ib puag ncig rhiab rau kev siv hluav taws xob tsis zoo los ntawm kev siv hluav taws xob los ntawm kev siv hluav taws xob. nyob rau hauv niaj hnub zog kev ruaj ntseg systems.
Nws qhov tseem ceeb yog feem ntau xav txog hauv nws txoj kev ua tiav hauv acoustic ib puag ncig phooj ywg. Cov tshuab hluav taws xob siv hluav taws xob niaj hnub, vim muaj kev ua haujlwm siab - lub cav ceev, kev vibration tshuab, thiab cov pa pulses, feem ntau ua suab nrov tshaj lub nroog ib puag ncig kev txwv, yooj yim cuam tshuam rau cov neeg nyob hauv lub neej, kev lag luam kev lag luam, thiab kev pabcuam pej xeem. Lub tshuab hluav taws xob uas ntsiag to siv ob - txheej suab tsis zoo, siab - suab nrov- nqus cov ntaub ntawv, damping vibration txo cov qauv, thiab lub labyrinthine kom tsawg thiab tso pa tawm tsim los thaiv nruab nrab - mus rau - suab nrov nrov 8} thiab tsis tshua muaj suab nrov. Ua ke nrog kev lag luam- qib mufflers rau kev tswj cov suab nrov nrov, kev khiav hauj lwm lub suab siab tuaj yeem raug txo kom ua tau raws li cov kev cai nruj ntawm "Environmental Noise Quality Standard" thiab cov chaw tshwj xeeb (xws li tsev kho mob, tsev kawm ntawv, thiab tsev so). Cov yam ntxwv no ua rau lawv tsis tuaj yeem hloov pauv hauv cov xwm txheej uas yuav tsum tau siv hluav taws xob thiab ib puag ncig nyob ntsiag to, zam kev tsis txaus siab, kev ua haujlwm nres, lossis ntxiv cov nqi txo suab nrov los ntawm cov teeb meem suab nrov, yog li tswj kev sib raug zoo ntawm kev ua haujlwm hauv zej zog.
Qhov thib ob, qhov tseem ceeb ntawm lub tshuab hluav taws xob uas ntsiag to ntawm lub tshuab hluav taws xob tau teeb tsa nyob rau hauv kev nthuav dav daim ntawv thov ciam teb ntawm cov tshuab hluav taws xob diesel. Nrog rau kev loj hlob sai thiab tsis tshua muaj av, ntau qhov kev thauj khoom tseem ceeb yog nyob hauv thaj chaw muaj neeg coob lossis thaj chaw muaj kev cuam tshuam ib puag ncig, xws li cov chaw khaws ntaub ntawv, chaw nres tsheb sib txuas lus, chaw nres tsheb thaum muaj xwm txheej ceev, siab -cov zej zog kawg, thiab cov phiaj xwm kev tsim kho vaj tse uas yuav tsum tau siv hmo ntuj. Cov khoom siv hluav taws xob ib txwm muaj txwv los ntawm lub suab nrov, ua rau kev xa ncaj qha nyuaj. Lub tshuab hluav taws xob uas ntsiag to, los ntawm kev siv tshuab suab nrov, tuaj yeem ruaj khov muab cov ntaub ntawv thaub qab lossis lub zog tseem ceeb hauv cov xwm txheej no, ua kom cov khoom siv kho mob tsis tu ncua, kev sib txuas lus tsis cuam tshuam, kev ua lag luam ib txwm muaj, thiab kev yooj yim ntawm cov neeg nyob hauv lub neej, txuas qhov sib txawv ntawm siab - kev ntseeg siab ntawm lub hwj chim thiab qis - suab nrov.
Tsis tas li ntawd, lawv qhov tseem ceeb nyob hauv lawv qhov kev txhawb nqa ob rau lub zog txuas ntxiv thiab kev sib raug zoo- nyob. Thaum muaj xwm txheej ceev xws li kev puas tsuaj ntuj tsim thiab hluav taws xob tsis ua hauj lwm, cov twj siv hluav taws xob uas ntsiag to ntawm lub tshuab hluav taws xob tuaj yeem pib sai thiab muab lub zog ruaj khov, ua kom muaj kev ua haujlwm ntawm lub neej kev txhawb nqa, teeb pom kev zoo thaum muaj xwm txheej ceev, thiab cov khoom siv sib txuas lus, yuav lub sijhawm rau kev puas tsuaj thiab kev noj qab haus huv rau pej xeem. Nyob rau tib lub sijhawm, lawv cov suab nrov tsawg- txo qis kev cuam tshuam nrog kev ua haujlwm kub ntxhov, txhim kho kev cawm dim thiab kev nplij siab ntawm cov neeg ua haujlwm. Hauv cov ntawv thov niaj hnub, lawv zam kev tsis sib haum xeeb los ntawm cov suab nrov, pab cov lag luam thiab cov koom haum ua tiav lawv cov luag haujlwm ib puag ncig thiab ua raws li qhov xav tau ntawm kev tsim ntsuab.
Tsis tas li ntawd, qhov tseem ceeb ntawm qhov ntsiag to diesel generator teeb tseem nyob hauv lawv qhov kev ua qauv qhia qhov tseem ceeb. Nws sib sib zog nqus tswj lub suab nrov nrog lub zog ua haujlwm, tsav kev tsim kho tshiab hauv cov tshuab hluav taws xob diesel hluav taws xob hla cov ntaub ntawv tshawb fawb, acoustic engineering, thiab kev tswj ntse. Nws muab cov lus qhia txog kev siv suab nrov txo kev tsim ntawm lwm cov khoom siv hauv kev lag luam, txhawb kev txhim kho ntawm tag nrho cov khoom siv hluav taws xob tsim kev lag luam mus rau ib puag ncig tus phooj ywg thiab cov neeg siv ntau dua - kev coj tus phooj ywg.
Hauv kev xaus, cov twj siv hluav taws xob uas ntsiag to tsis yog tsuas yog kev daws teeb meem rau cov teeb meem muaj kuab paug suab nrov xwb, tab sis kuj tseem muaj cov cuab yeej tseem ceeb rau kev ntsuas kev ruaj ntseg ntawm lub zog thiab ib puag ncig kev vam meej, nthuav dav daim ntawv thov scenarios, thiab txhawb kev txhim kho kev sib raug zoo. Lawv qhov tseem ceeb yuav tau hais ntxiv nrog rau kev nce qib ntawm nroog loj thiab decarbonization, muab kev txhawb nqa tseem ceeb rau kev tsim kom muaj kev noj qab haus huv thiab txhim khu kev qha niaj hnub siv hluav taws xob.
