Sound meter : SPL & dB meter

Imitha Yomsindo yaziwa nangokuthi imitha yezinga lokucindezela komsindo (imitha ye-SPL), imitha yezinga lomsindo, imitha ye-decibel (imitha ye-dB), imitha yezinga lomsindo noma imitha yomsindo. Kuyinsiza ewusizo kakhulu ukwenza isivivinyo somsindo noma ukukala umsindo wendawo (isivivinyo somsindo).

Imitha yezinga lomsindo noma imitha yezinga lokucindezela komsindo (imitha ye-SPL) isebenzisa imakrofoni ye-smartphone noma yethebhulethi ukukala umsindo wendawo ngama-decibel (i-dB). Inani le-decibel (i-dB) lale mitha yezinga lomsindo noma imitha yomsindo lingahluka uma liqhathaniswa nemitha yomsindo yangempela (imitha ye-dB). Manje ungenza kalula isilinganiselo somsindo ngefoni yakho ehlakaniphile.


Isexwayiso:
Inani lemitha ye-decibel noma imitha yomsindo (imitha ye-dB) aliqondile njengemitha yezinga lokucindezela komsindo yangempela (imitha ye-SPL), imitha yomsindo, imitha ye-decibel noma imitha yezinga lomsindo, lokhu kungenxa yokuthi imakrofoni eminingi yedivayisi ihambisana nezwi lomuntu. Ukuze ulungise lokhu, sebenzisa imitha yomsindo yangempela noma imitha yomsindo (imitha ye-SPL) ukuze ulungise iphutha lama-decibel eduze ngangokunokwenzeka ngaphambi kokusebenzisa. Uma ubungenawo imitha yomsindo yangempela (imitha ye-SPL), iya endaweni ethule kakhulu lapho umsindo ungezwa khona bese ulungisa inani lokufunda libe ngu-20~30dB.

Isici:
- Linganisa umsindo wendawo kanye nomsindo
- Isibuyekezo sesikhathi sangempela kugrafu yeshadi
- Bonisa ubuncane (Obuncane), ubukhulu (Obukhulu) kanye nesilinganiso (I-Avg) Decibel (dB) esimisweni sokurekhoda
- Isikhathi sokulinganisa sokubonisa
- Inkinobho Yokusetha kabusha inikezwa uma kwenzeka udinga ukusetha kabusha ukulinganisa
- Dlala bese umisa inkinobho inikezwa
- Ukuhlolwa komsindo noma ukuhlolwa komsindo (imitha ye-decibel noma imitha ye-dB)

Izinga lomsindo wemitha yomsindo noma imitha ye-decibel (imitha ye-dB)

Umsindo omkhulu uzoba yingozi empilweni yakho yomzimba neyensimbi. Kufanele ugweme ukuchayeka kuleyo ndawo. Vumela imitha yethu yomsindo/imitha yomsindo ukukala umsindo wendawo. Unganqikazi ukulanda Imitha Yomsindo ukuze uvikele impilo yakho neyomndeni wakho.
