Bayanin samfur
ROGA Instruments SLM da SPM Module Manual yana ba da hanya mai sauƙi don ƙayyade matakan ƙarfin sauti bisa ga ƙa'idodi. Tsarin SLM yana auna matakan matsi na sauti a dB daga siginar lokaci, yawanci siginar makirufo. Samfurin SPM yana ƙididdige ƙarfin sauti daga matakan matsin sauti tare da duk sharuddan gyaran da suka dace.
SLM Module
Ma'aunin Lokaci
Tsarin SLM yana ba da ma'auni daban-daban na lokaci:
- AZUMI: Matsakaicin raguwar nauyi tare da tsayayyen lokaci na 125 ms
- SAUKI: Matsakaicin raguwar nauyi tare da tsayayyen lokaci na 1000 ms
- Ƙarfafawa: Matsakaicin raguwar nauyi don haɓaka (35 ms) da raguwa (1500 ms) matakan
- Leq: Daidai ci gaba da matakin matsa lamba
- Kololuwa: Cikakken madaidaicin matsi na sauti nan take
- An ayyana mai amfani: Matsakaicin lokacin daidaitawa don tashin sigina da faɗuwa
Yawan Ma'aunin nauyi
- Tsarin SLM yana goyan bayan lissafin ma'aunin mitar A, B, C, da LINEAR bisa ga IEC 651. Daidaiton ya dogara da s.ampling mita na shigar da siginar.
Ma'aunin Ma'aunin Shigarwa
Yana gabatar da ma'auni na mitar siginar shigarwa:

Da fatan za a lura cewa kewayo mai ƙarfi musamman tare da ƙananan mitoci ya dogara da matsayi na ma'aunin nauyi a cikin siginar siginar, ko ana yin ma'aunin mitar kafin ko bayan ADC (Analog/Digital-Converter).
Tsohonample
Kuna da siginar amo tare da sassan 100 dB a 20 Hz da 30 dB a 1 kHz kuma kuna buƙatar matakin A-nauyin (dbA), ADC yana da cikakken ma'auni na 60 dB.
A-weighting tace kafin ADC
Alamar 20 Hz-Signal ita ce damped ta 50,5 dB zuwa 49,5 dB, siginar 1 kHz ya kasance koyaushe. Jimlar tana ƙasa da 60 dB kuma ana iya samun shi daidai zama ADC.
Ana iya yin awo.
A-weighting tace bayan ADC
Alamar 20 Hz-Signal tare da 100 dB yana haifar da wuce gona da iri na ADC.
Ba za a iya yin Ma'auni ba.
Don ɗaukar ma'auni duk da haka, dole ne a daidaita cikakken sikelin, ta yadda ADC zata iya ɗaukar 100 dB. Sashin 1 kHz tare da 30 dB-Signal shine 70 dB ƙasa da cikakken sikelin kuma za a gurbata shi ta hanyar amo. Musamman, idan kuna buƙatar A-weighting, kuma akwai babban rabo a ƙananan mitoci, a hardware A-weighting kafin ADC da karfi da shawarar.
High Pass 10 Hz
Don murkushe ƙaramar ƙarar mitar ana samar da matatar wucewa mai girma. Yana da matattarar sandar igiya biyu tare da yanke 10 Hz. Idan ka duba akwati, ana amfani da tacewa, in ba haka ba.
Daidaitawa
Don ba da damar nunin matakan amo a dB, dole ne a daidaita tsarin.
Akwai hanyoyi guda biyu don daidaita tashoshi na module
Calibration ta amfani da calibrator
Duba akwatin 'kunna' a cikin akwatin rukuni' Calibration tare da calibrator', shigar da matakin calibrator ɗin ku kuma fara aunawa.
Ana nuna maganganu don saka idanu akan matsayin daidaitawa (SLM calibration'). Idan fiye da ɗaya SLM-modules an sanya su akan tsari dole ne a yi calibration ga kowannen su daban.
Idan ka toshe calibrator zuwa daya daga cikin makirufo, matakin wannan makirufo ya tsaya tsayin daka na wani lokaci (Nuni ‚Level is dindindin xx % tare da xx na 0 .. 100) kuma ta amfani da wannan matakin da matakin da aka bayar, ana ƙididdige bambancin calibrator kuma an daidaita shi (nuni ‚ƙimar calibration ana ɗauka ‚darajar’ ginshiƙin darajar’ da ƙimar darajar). An gama daidaita ma'aunin wannan tasha kuma ana iya shigar da calibrator akan makirufo na gaba har sai kun sami nuni.
Odar da kuka daidaita makirufo ba ta da matsala. Ana gano makirufo tare da calibrator toshe a kunne ta atomatik ta matsakaicin matakin.
Don makirufo, ba tare da calibrator matakin shigarwa ya bambanta (nuni ‚matakin yana canzawa) kuma ana yin gyare-gyare don waɗannan tashoshi.
Shigar da hankali kai tsaye na makirufo
Danna maɓallin 'Sensitivities' a cikin akwatin rukuni 'Sensor Sensitivities'. Za a nuna tattaunawar daidaitawa inda za ku iya view kuma shigar da hankalin makirufo.
Shigar da hankalin makirufo a cikin ginshiƙi 'shigarwar hannu' kuma danna 'Aiwatar shigar da hannu'.
SPM Module
SPM-module (Aunawar Ƙarfin Sauti) yana ƙayyade ƙarfin sauti daga wasu matakan matsin sauti dangane da duk sharuddan gyara da suka dace.
Abubuwan shigarwa
SPM-module yana da abubuwan shigarwa 1 zuwa 16 waɗanda za a iya kunnawa da kashe su ta maɓallan ‚+' – da ‚-’ –. Abubuwan shigar suna tsammanin matakan a dB (yawanci suna zuwa daga SLM-modules).
Fitowa
Tsarin SPM yana da fitarwa ɗaya don matakin ƙarfin sauti.
Sharuddan gyarawa
Don tantance ƙarfin sauti bisa ga ma'auni, dole ne a la'akari da sharuddan gyara:
- K0 gyaran gyare-gyare don matsa lamba na barometric da zafin jiki, duba DIN 45 635, sakin layi na 7.1.4.
- Kalmar gyara K1 don hayaniyar baya, duba DIN 45 635, sakin layi na 7.1.3.
- Kalmar gyara K2 don tasirin muhalli, duba DIN 45 635, sakin layi na 7.1.4.
- Ls gyaran gyare-gyare don girman girman rufin, duba DIN 45 635, sakin layi na 6.4., 7.2.
Lokacin gyara don matsa lamba barometric da zafin jiki K0
- Maganar gyara don matsa lamba na barometric da zafin jiki, duba DIN 45 635, sakin layi na 7.1.4.
Shigar da zafin jiki a filin shigarwa ''Zazzabi' da matsi na barometric a cikin filin shigarwa ''Barometric Pressure'. Ana nuna kalmar gyarawa a cikin filin ''K0 Setting'.
Dangane da DIN 45 635, don daidaiton darajar 2 K0 ba lallai ba ne, a cikin ma'aunin ISO 374x ba a ambace shi kwata-kwata. Don haka kuna iya zaɓar don amfani da K0 ko ba don ƙididdigewa ba (akwatin rajista ''Yi amfani da K0').
Kalmar gyara don hayaniyar baya K1
Maganar gyara don hayaniyar baya, duba DIN 45 635, sakin layi na 7.1.3.
Ɗauki awo tare da kashe ɗan takara. Don haka kuna iya ayyana wannan matsi na sauti ya zama hayaniyar bango (maɓallin ''Saita hayaniyar bango zuwa ma'auni na ƙarshe'), ko shigar da matakin matsin sautin saman da ke lulluɓe (= matakin ƙarfin sauti - Ls) na hayaniyar bango kai tsaye (filin shigarwa ''Background amo').
Lura, cewa dole ne a ɗauki ma'aunin amo na baya tare da ma'aunin mitar daidai da ma'aunin mai zuwa.
Haƙiƙanin ƙimar K1 ya dogara da sigina zuwa ƙimar hayaniyar baya kuma ana ƙididdige shi akan layi yayin aunawa. Idan adadin kuzarin siginar bayanai da hayaniyar baya bai wuce 3 dB sama da amo na bango ba, ba za a iya ƙididdige lokacin gyara K1 ba kuma an saita fitowar samfurin zuwa -1000.0 dB.
Lokacin gyara don tasirin muhalli K2
Maganar gyara don tasirin muhalli, duba DIN 45 635, sakin layi na 7.1.4. Kuna iya ƙayyade tasirin muhalli ta hanyoyi biyu:
Shigarwa kai tsaye
Shigar da K2 kai tsaye a dB a cikin filin shigarwa ''K2 Setting'.
Lissafin K2 ta hanyar kaddarorin dakin aunawa
Shigar da ma'auni (tsawo, faɗi da zurfi a cikin filayen shigarwa ''Tsawon', 'Nisa' da' Zurfin') da ma'anar ƙimar sha (filin shigarwa ''Ma'anar sha'awa') ko lokacin sake maimaita kejin gwajin (filin shigarwa ''Lokacin Reverberation') na kejin gwajin.
Da fatan za a lura, cewa dole ne ku ƙididdige lokacin gyara don girman rufin Ls kafin kimantawar K2.
Lokacin gyara don girman rufin rufin Ls
Maganar gyara don girman rufin rufin, duba DIN 45 635, sakin layi na 6.4., 7.2. Kuna iya shigar da rabon saman lullubi zuwa 1m² kai tsaye a cikin dB (filin shigarwa ''Ls Setting') ko saman lullube a cikin murabba'in mita (filin shigarwa '' fuskar sawa', zaɓi ''Input Direct').
Hakanan kuna iya ƙididdige saman lulluɓe ta siffarsa da girmansa:
Sphere
Don lissafin dole ne a san radius.
Hemisphere
Don lissafin dole ne a san radius
Cuboid ya rabu
Don lissafin bangarorin 2a, c da 2b dole ne a san su.
Cuboid a bango da rufi
Don lissafin bangarorin 2a, c da 2b dole ne a san su.
Cuboid a bango
Don lissafin bangarorin 2a, c da 2b dole ne a san su.
