Yuav ua li cas txiav txim seb tus nqi ntsuas ntawm lub suab nrov ntsuas ntsuas yog qhov tseeb?
Noise tester, ib qho cuab yeej rau kev ntsuas suab nrov, tseem hu ua suab nrov ntsuas, ntsuas suab nrov, ntsuas suab nrov, ntsuas suab nrov, ntsuas suab nrov, ntsuas suab nrov, thiab lwm yam. Raws li kev ntsuas qhov tseeb, nws tuaj yeem muab faib ua Chav Kawm 1 suab ntsuas ntsuas thiab Chav Kawm 2 suab ntsuas ntsuas; Raws li cov khoom siv, nws tuaj yeem muab faib ua tes tuav, ntau lub luag haujlwm, ib qho, lub suab nrov spectrum analyzer, tus kheej lub suab raug ntsuas, thiab lwm yam. Cov cuab yeej siv suab nrov thiab cov cuab yeej siv feem ntau suav nrog:
Multifunctional Sound Level Meter
A, C, Z zaus qhov hnyav thiab F, S, Kuv lub sijhawm hnyav; Kev txheeb cais, kev sib koom ua ke, 1/1OCT, 1/3OCT, FFT thiab cov ntaub ntawv digital; dav siv nyob rau hauv kev tiv thaiv ib puag ncig, kev ua haujlwm tu cev, kev lag luam kev lag luam, kev tshawb fawb thiab kev qhia, thiab lwm yam hauv kev ntsuas suab nrov ntawm ib puag ncig, kev ntsuas suab lub zog, kev ntsuas lub suab nrov ntawm lub tshuab thiab cov khoom siv hluav taws xob acoustic.
Noise Spectrum Analyzer
Tso tawm lub suab siab ntawm txhua zaus taw tes ntawm 1/1 octave lim; nws tuaj yeem ntsuas lub suab nrov hauv tshav dav hlau thiab suav Td, LEPN, LAmax, LA'max.
Precision Integral Sound Level Meter
Ib qho kev sib xyaw nruab nrab ntawm lub suab ntsuas uas tuaj yeem ntsuas lub sij hawm nruab nrab suab theem thiab ib qho kev sib xyaw suab qib ntsuas uas tuaj yeem ntsuas lub suab raug. Nws kuj tseem tuaj yeem ntsuas qhov ntsuas qhov feem pua ntawm cov suab thiab cov feem pua ntawm cov suab qib (cov lej ntsuas suab); Nws tuaj yeem siv dav hauv kev tiv thaiv ib puag ncig, Hauv kev ua haujlwm tu cev, kev lag luam kev lag luam, kev tshawb fawb thiab kev qhia, thiab lwm yam., ua kom tiav ib puag ncig kev ntsuas suab nrov, ntsuas suab nrov hauv tshav dav hlau, cov cuab yeej siv suab nrov ntsuas thiab ntsuas kev tsim vaj tsev acoustic.
Digital Sound Level Meter
A, C, Z zaus hnyav; F, S, I, Peak lub sij hawm hnyav; tuaj yeem siv rau kev ntsuas suab nrov ntawm ntau lub tshuab, tsheb, nkoj, khoom siv hluav taws xob, thiab lwm yam, thiab tseem tuaj yeem siv rau ib puag ncig suab nrov, kev tiv thaiv kev ua haujlwm, thiab kev ntsuas kev huv.
Octave Band Suab Level Meter
Ntau qhov kev soj ntsuam ua haujlwm, txheeb cais, kev sib koom ua ke, 1/1OCT, 1/3OCT, FFT thiab cov ntaub ntawv digital tuaj yeem pib synchronously lossis asynchronously; dav siv nyob rau hauv kev tiv thaiv ib puag ncig, kev ua haujlwm tu cev, kev lag luam kev lag luam, kev tshawb fawb thiab kev qhia, thiab lwm yam, kom ua tiav ib puag ncig kev ntsuas suab nrov, suab lub zog ntsuas qib, kev ntsuas suab nrov ntawm cov tshuab thiab cov khoom siv, thiab kev ntsuas lub suab nrov.
