Kunzwa kwemaikorofoni ndiko kupindurwa kwemagetsi kwekubuda kwayo kune yakapihwa standard acoustic input.Iyo yakajairwa referensi yekuisa chiratidzo inoshandiswa kuyera maikorofoni kuyerwa ndeye 94dB inonzwika kumanikidza level (SPL) kana 1 kHz sine wave pa1 Pa (Pa, chiyero chekumanikidza).Kune yakagadziriswa acoustic input, amaikorofoniine yakakwira yekunzwa kukosha ine yakakwira yekubuda level pane maikorofoni ine yakaderera kukosha kwekunzwa.Maikorofoni senitivity (inoratidzwa mu dB) kazhinji haina kunaka, saka iyo yakakwira yekunzwa, idiki kukosha kwayo kwakazara.
Izvo zvakakosha kuti ucherechedze mayuniti umo maikorofoni senitivity inoratidzwa.Kana manzwiro emakrofoni maviri asina kutaurwa muchikamu chimwe chete, kuenzanisa kwakananga kwekunzwa kukosha hakuna kukodzera.Kunzwa kweanalog maikorofoni kunowanzo kutsanangurwa mudBV, iyo nhamba yedB inoenderana ne1.0 V rms.Kunzwa kwemakrofoni yedhijitari kunowanzo kutsanangurwa mudBFS, inova nhamba yedB inoenderana neyakakwana-chiyero chinobuda dijitari (FS).Kune maikorofoni edhijitari, chiratidzo chakazara-chiyero ndicho chepamusoro chiratidzo chepamusoro maikorofoni inogona kubuda;yeAnalog Devices MEMS maikorofoni, iyi nhanho ndeye 120 dBSPL.Ona chikamu cheMaximum Acoustic Input kuti uwane tsananguro izere yeiyi chiratidzo nhanho.
Sensitivity (sensitivity) zvinoreva chiyero chekuisa simba kune kubuda kwemagetsi (voltage kana digital).Kune analog maikorofoni, senitivity inowanzoyerwa muMV/Pa, uye mhedzisiro inogona kushandurwa kuita dB kukosha ne:
Kunzwa kwepamusoro hakurevi kuita zvirinani maikorofoni.Iyo yakakwira kunzwisiswa kwemaikorofoni, iyo shoma margin iyo inowanzova pakati peyero yekuburitsa uye yakanyanya kuburitsa nhanho pasi pezvakajairwa mamiriro (sekutaura, nezvimwewo).Munzvimbo yepedyo-(yepedyo kutaura) maapplication, mamaikorofoni ane hanya zvakanyanya anogona kunge ari nyore kukanganisa, izvo zvinowanzo dzikisa huwandu hwese hwesimba hwemakrofoni.
