Kev daws teeb meem rau Kev Ua Phem Tsis Zoo ntawm Noise Meter thiab Kev Kho Hniav Noise Meter
1. Tsis muaj qhov tso tawm ntawm cov zaub
(1) Kev sib txuas ntawm lub roj teeb sab hauv yog txiav tawm lossis lub roj teeb tiv thaiv tsis zoo: solder qhov kev sib txuas thiab hloov lub roj teeb tiv tauj.
(2) Lub roj teeb puas lawm: hloov lub roj teeb.
2. Qhov ntsuas ntsuas tau pom tseeb qis lossis qhov ntsuas ntsuas tsawg dua 94.0dB.
(1) Microphone rhiab heev yog tsawg los yog puas: hloov lub microphone thiab recalibrate.
(2) Cov kev sib cuag ntawm lub preamplifier tsis zoo nrog lub microphone: ntxuav cov neeg sib cuag.
(3) Lub ntsaws ntawm lub preamplifier tsis nyob rau hauv kev sib cuag zoo nrog lub qhov (socket) host: hloov lub ntsaws ntsaws.
3. Kev nyeem ntawv siab dhau thaum ntsuas suab qis, thiab cov xaim hauv av ntawm lub preamplifier tsis nyob rau hauv kev sib cuag zoo: nruj lub tes tsho sab nraud.
Nrog rau cov teeb meem tseem ceeb ntawm ib puag ncig, kev tiv thaiv thiab tswj cov suab nrov nrov kuj tau muab tso rau hauv cov txheej txheem, yog li cov suab nrov nrov tau los ua.
Tab sis kuv ntseeg tias ntau tus neeg tseem tsis paub txog nws txoj haujlwm ua haujlwm, thiab qee tus neeg txawm tsis ntseeg qhov kev ua tau zoo ntawm lub suab nrov digital, yog li cia peb pib nrog cov yam ntxwv ntawm nws cov txheej txheem thev naus laus zis.
Cov ntsiab lus tseem ceeb ntawm digital suab ntsuas ntsuas:
Txoj kev suav ua raws li cov kev cai ntawm "Calculation Method for Attenuation of Outdoor Sound Propagation" (ISO 9613-2:1996)) thiab "Technical Guidelines for Environmental Impact Assessment Acoustic Environment" (HJ 2.4-2009), xav txog lub suab diffraction, reflection thiab refraction algorithms; Lub suab kwv yees qhov tseeb ntawm lub suab ncaj qha tsis tsawg dua 3 dB (A).
Lub hauv paus ntsiab lus ntawm digital suab qib ntsuas:
Nws yog qhov yooj yim tshaj plaws thiab feem ntau siv cov cuab yeej hauv kev ntsuas acoustic, thiab yog siv dav los ntsuas lub suab siab lossis qib suab ntawm lub suab.
Lub ntsuas suab qib digital ntxiv cov haujlwm digital ua haujlwm raws li cov ntsuas suab nrov zoo tib yam, ua rau kev ua haujlwm yooj yim dua thiab yooj yim dua.
Nws tsis yog tsuas yog siv nyob rau hauv acoustic thiab electroacoustic ntsuas, tab sis kuj tau lug siv nyob rau hauv ntau yam teb xws li tshuab manufacturing, architectural tsim, tsheb thauj mus los, ib puag ncig tiv thaiv, kev kho mob thiab kev noj qab haus huv, thiab lub teb chaws tiv thaiv engineering, thiab tau los ua ib tug yuav tsum-muaj acoustic. ntsuas ntsuas rau yuav luag txhua chav haujlwm.
Technical nta ntawm digital suab qib ntsuas:
Kev simulation hauv computer, database technology, Internet of Things, cloud computing, thiab lwm yam., cia siab rau kev tshawb fawb acoustic qauv kom paub 3D visualization ntawm suab paj nruag daim duab kos duab;
Ua tib zoo kwv yees tus qauv ntawm ib puag ncig lub suab hloov pauv hauv cheeb tsam, tswj qhov zoo ntawm qhov chaw acoustic, thiab muab kev txhawb zog rau kev tswj hwm ib puag ncig suab nrov.
