Suab - qib meter , ntaus ntawv ntsuas qhov siv ntawm lub suab nrov, suab paj nruag, thiab lwm yam suab . Ib yam meter muaj lub microphone rau khaws cov suab thiab converting nws mus rau hauv ib tug hluav taws xob teeb liab, ua raws li hluav taws xob circuitry rau kev khiav hauj lwm ntawm lub teeb liab no kom cov yam ntxwv xav tau tuaj yeem ntsuas.
Ib yam li ntawd, lub hom phiaj ntawm lub suab ntsuas lub suab yog dab tsi?
A suab qib meter yog ib qho kev ntsuas uas siv los ntsuas suab nrov los yog suab theem los ntawm kev ntsuas suab siab . Feem ntau hu ua a suab siab theem ( SPL ) meter , decibel (dB) meter , suab meter los yog suab nrov dosimeter, lus qib meter siv lub microphone los ntes suab.

Ntawm no, koj siv lub ntsuas suab li cas?
Pib pib
- Tig lub Suab Qib Meter los ntawm zawv zawg Lub Hwj Chim / Ntsuas Hloov mus rau qhov ntsuas qhov tsim nyog (35–90 lossis 75–130 dB).
- Txuas lub mini-kawg plug ntawm lub cable mus rau lub Suab Level Meter thiab txuas lwm kawg ntawm lub cable mus rau lub interface (LabQuest Mini, LabQuest 2, thiab lwm yam).
100 dB suab zoo li cas?
Decibels piav
| Decibel Qib | Qhov chaw |
|---|---|
| 70-90 dB | Lub tsheb ua si |
| 88dB ib | Subway, maus taus |
| 85-90 dB | Lawnmower |
| 100 dB | Tsheb ciav hlau, tsheb khib nyiab |

Dab tsi ua rau lub qhov hluav taws xob muaj hluav taws xob tsawg?
Ib qho laj thawj uas lub qhov hluav taws xob yuav muaj lowvoltageis uas nws hnav tawm. Cov hluav taws xob hluav taws xob tuaj yeem hnav tawm tib yam li txhua yam khoom siv lossis cov khoom siv hluav taws xob.Qhov txuas tsis tu ncua thiab tshem tawm cov hlua rau hauv lub qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas
Chav hluav taws xob hloov hluav taws xob yog dab tsi?
Chav hloov. ib cheeb tsam uas muaj kev sib dhos ntawm cov khoom siv hluav taws xob rau kev tswj thiab kev tiv thaiv hluav taws xob circuits. chav hloov pauv tuaj yeem cuam tshuam rau lub substation tab sis tsuas muaj cov keyboards xwb. lub ntsiab hloov mus rau cais tawm hluav taws xob yog nyob rau hauv lub ntsiab switchroom
Yuav ua li cas koj xaim lub tshuab hluav taws xob mus rau qhov ntsuas hluav taws xob?
Muaj peb cov xov hlau uas yuav tsum tau txuas mus rau qhov tseeb regulator davhlau ya nyob twg. Weld lub regulator mount rau lub tsheb laij teb ncej. Txuas lub regulator rau lub mount. Txuas lub roj teeb zoo cable hlau - feem ntau yog liab - rau tus tswj. Polarize lub generator los yog alternator los ntawm tus regulator
Koj siv lub ntsuas hluav taws xob ntsuas hluav taws xob li cas?
Txhawm rau siv lub ntsuas hluav taws xob, kov ib qho kev sojntsuam rau ib lub xaim lossis kev sib txuas thiab lwm qhov kev sojntsuam mus rau qhov sib txawv ntawm cov xaim lossis kev sib txuas
Puas yog txhua lub tshuab hluav taws xob muaj GFCI qhov hluav taws xob?
Duplex (ob chav) qhov hluav taws xob muaj nyob rau ntawm lub tshuab hluav taws xob nqa tau thiab txhua qhov khoom siv 120 volts. Hauv av txhaum kev tiv thaiv qhov hluav taws xob (GFCI) yog qhov tshwj xeeb ntawm qee cov qauv thiab tiv thaiv tus neeg siv los ntawm hluav taws xob shocks
