Kumverera kwa maikolofoni

Kukhudzika kwa maikolofoni ndiko kuyankhidwa kwamagetsi komwe kumatuluka kumayendedwe operekedwa mulingo wamayimbidwe.Chizindikiro cholozera chomwe chimagwiritsidwa ntchito poyezera kukhudzidwa kwa maikolofoni ndi 94dB sound pressure level (SPL) kapena 1 kHz sine wave pa 1 Pa (Pa, muyeso wa kupanikizika).Kuti mulowetse mawu okhazikika, amaikolofoniyokhala ndi mtengo wokhudzika kwambiri imakhala ndi mulingo wapamwamba kwambiri wotulutsa kuposa maikolofoni yokhala ndi mtengo wotsika.Kumverera kwa maikolofoni (kufotokozedwa mu dB) nthawi zambiri kumakhala koyipa, kotero kukhudzika kwamphamvu, kumachepetsa mtengo wake wonse.
Ndikofunika kuzindikira mayunitsi omwe mafotokozedwe a maikolofoni amawonekera.Ngati kukhudzika kwa ma maikolofoni awiriwa sikunatchulidwe mugawo lomwelo, kufananitsa kwachindunji kwamalingaliro sikoyenera.Kukhudzika kwa maikolofoni ya analogi nthawi zambiri kumatchulidwa mu dBV, chiwerengero cha dB chokhudzana ndi 1.0 V rms.Kukhudzika kwa maikolofoni ya digito nthawi zambiri kumatchulidwa mu dBFS, yomwe ndi nambala ya dB yokhudzana ndi kutulutsa kwa digito (FS).Kwa maikolofoni adijito, siginecha yathunthu ndimlingo wapamwamba kwambiri womwe maikolofoni imatha kutulutsa;kwa Analog Devices MEMS maikolofoni, mlingo uwu ndi 120 dBSPL.Onani gawo la Maximum Acoustic Input kuti mumve zambiri za siginoyi.
Sensitivity imatanthawuza chiŵerengero cha mphamvu yolowera ku magetsi (voltage kapena digito).Kwa maikolofoni a analogi, kukhudzika nthawi zambiri kumayesedwa mu mV/Pa, ndipo zotsatira zake zimatha kusinthidwa kukhala dB mtengo ndi:
Kukhudzika kwakukulu sikutanthauza kuti maikolofoni azichita bwino nthawi zonse.Kukhudzika kwa maikolofoni kumapangitsa kuti malire ake azikhala ocheperako pakati pa mulingo wake wotulutsa ndi mulingo wambiri wotulutsa pansi pamikhalidwe wamba (monga kuyankhula, ndi zina).M'mapulogalamu apafupi (pafupifupi), maikolofoni okhudzidwa kwambiri amatha kukhala osokonekera, zomwe nthawi zambiri zimachepetsa kuchuluka kwamphamvu kwa maikolofoni.
