Lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab kev siv lub suab nrov sensor
Qhov cuam tshuam ntawm lub suab nrov ntawm cov kab mob hauv lub cev yog cov txheej txheem uas txav los ntawm physiology mus rau pathology. Pathological kev puas tsuaj yuav tsum ncav cuag ib qho kev siv thiab lub sij hawm raug. Cov kev hloov hauv qhov hnov qhov kev puas tsuaj los ntawm lub suab tsis zoo feem ntau tshwm sim los ntawm kev hloov ntawm qhov hnov lus ib ntus mus rau qhov kev hnov lus dav. Kev puas tsuaj ntawm suab nrov rau tib neeg lub cev yog systemic. Nws tuaj yeem tsis tsuas yog ua rau muaj kev hloov pauv hauv lub cev auditory, tab sis kuj cuam tshuam rau cov tshuab tsis hnov lus. Tsis tas li ntawd, suab nrov hauv chaw ua haujlwm kuj tuaj yeem cuam tshuam nrog kev sib txuas lus, cuam tshuam rau kev ua haujlwm ntawm kev ua haujlwm, thiab ua rau muaj xwm txheej.
Hauv kev tsim khoom thiab lub neej, suab nrov cuam tshuam yog nyob txhua qhov chaw. Txhawm rau kom ntseeg tau tias tib neeg nyob ib puag ncig, cov tuam tsev muaj feem cuam tshuam nrog cov qauv tsim los tsim cov kev txwv ib puag ncig lub suab nrov emission txwv thiab ntsuas txoj hauv kev ntawm thaj tsam ntawm cov tuam txhab lag luam thiab cov khoom lag luam ruaj khov. Yog li dab tsi peb yuav tsum xyuam xim rau hauv kev saib xyuas suab nrov?
1. Kev saib xyuas yam
Feem ntau, lawv yog Ld (sib npaug A suab theem nruab nrab ntawm cov qe) thiab Ln (sib npaug sib npaug A suab theem thaum hmo ntuj). Thaum muaj suab nrov nrov lossis nrov nrov, Lmax (loj A suab qib) yuav tsum ntsuas tib lub sijhawm thaum hmo ntuj [Lmax yuav tsum sau cov lus tsim nyog dhau los]
2. Saib xyuas qhov taw qhia layout
Txoj cai dav dav yog tias nws tuaj yeem xaiv sab nraum lub tsev nrov nrov, 1m deb ntawm phab ntsa lossis qhov rais, thiab tsawg kawg 1.2m saum av.
3. Saib xyuas lub sijhawm thiab zaus
Ib puag ncig lub suab soj ntsuam ntawm cov tsev rhiab yuav tsum ntsuas raws li kev ua haujlwm ib txwm muaj ntawm cov suab nrov ib puag ncig. Raws li kev ua haujlwm ntawm lub suab nrov, nws yuav tsum tau nqa tawm tsis tu ncua hauv ob lub sijhawm: nruab hnub thiab hmo ntuj. Nyob ntawm cov yam ntxwv ntawm ib puag ncig lub suab nrov, lub sijhawm ntsuas tuaj yeem ua kom zoo. Nws tau muab faib ua cov suab nrov ruaj khov thiab cov suab nrov nrov (cov suab nrov mobile).
(1) Kev cuam tshuam ntawm lub suab ruaj khov
Lub Sijhawm Saib Xyuas: Lub suab sib npaug ntawm lub suab nrov tsis tu ncua yog ntsuas rau 1 feeb. Piv txwv li, Ld yog tau los ntawm kev ntsuas rau 1 feeb thaum nruab hnub, thiab Ln yog tau los ntawm kev ntsuas rau 1 feeb thaum hmo ntuj. Lub suab nrov tsis ruaj khov ntsuas qhov sib npaug ntawm lub suab nyob rau tag nrho lub sijhawm ua haujlwm (lossis lub sijhawm sawv cev).
Kev saib xyuas ntau zaus: Feem ntau, tsis pub tsawg tshaj 2 hnub ntawm kev saib xyuas tas li, 2 zaug ib hnub thiab hmo ntuj, uas yog, ib hnub ib hnub ntawm hnub qub thiab ib zaug thaum hmo ntuj.
(2) Cov chaw suab nrov (tsav qhov chaw suab)
Lub sijhawm saib xyuas:
Rau kev khiav tsheb, kev ntsuas nruab hnub thiab hmo ntuj yuav tsum tsis txhob qis dua 20-feeb suab sib npaug Leq ntawm qhov nruab nrab khiav ceev.
Rau kev tsheb ciav hlau, kev tsheb ciav hlau hauv nroog (hauv av seem), thiab cov dej hauv av, kev ntsuas nruab hnub thiab hmo ntuj yuav tsum tsis txhob qis dua 1h sib npaug suab qib Leq ntawm qhov nruab nrab khiav ceev. Yog tias txoj kev tsheb ciav hlau hauv nroog (hauv av seem) ua haujlwm hnyav, lub sijhawm ntsuas tuaj yeem luv luv rau 20min.
Kev soj ntsuam zaus:
Feem ntau, kev soj ntsuam tas mus li yuav tsum tsis pub tsawg dua 2 hnub, ob zaug thaum nruab hnub thiab ob zaug thaum hmo ntuj, uas yog, ib zaug thaum nruab hnub thiab ib zaug thaum tsaus ntuj.
Hauv kev soj ntsuam suab nrov, suab nrov sensors yog qhov tseem ceeb tshwj xeeb. Noise sensors yog lub hauv paus ntawm kev saib xyuas suab nrov. Qhov tseeb ntawm kev soj ntsuam cov ntaub ntawv suab nrov kuj nyob ntawm cov suab nrov sensors.
