ʻO ka ʻike microphone

ʻO ka sensitivity o kahi microphone ka pane uila o kāna hoʻopuka i kahi hoʻokomo acoustic maʻamau.ʻO ka hōʻailona hoʻokomo kuhikuhi maʻamau i hoʻohana ʻia no nā ana ʻike microphone he 94dB kani kani (SPL) a i ʻole he hawewe sine 1 kHz ma 1 Pa (Pa, kahi ana o ke kaomi).No ka hookomo acoustic pa'a, amicrophoneʻoi aku ka kiʻekiʻe o ka ʻike ma mua o ka microphone me ka haʻahaʻa haʻahaʻa.ʻAʻole maʻamau ka noʻonoʻo microphone (i hōʻike ʻia ma ka dB), no laila ʻoi aku ka kiʻekiʻe o ka ʻike, ʻoi aku ka liʻiliʻi o kona waiwai paʻa.
He mea nui e hoʻomaopopo i nā ʻāpana kahi i hōʻike ʻia ai ka ʻike kikoʻī o ka microphone.Inā ʻaʻole i kuhikuhi ʻia nā sensitivities o nā microphones ʻelua i ka ʻāpana like, ʻaʻole kūpono ka hoʻohālikelike pololei ʻana i nā waiwai sensitivity.Hōʻike pinepine ʻia ka ʻike o kahi microphone analog ma dBV, ka helu o dB pili i 1.0 V rms.Hōʻike pinepine ʻia ka ʻike o kahi microphone kikohoʻe ma dBFS, ʻo ia ka helu o dB pili i ka puka kikohoʻe piha piha (FS).No nā microphones kikohoʻe, ʻo ka hōʻailona piha piha ka pae hōʻailona kiʻekiʻe loa i hiki i ka microphone ke hoʻopuka;no nā microphones MEMS Analog Devices, he 120 dBSPL kēia pae.E ʻike i ka ʻāpana Maximum Acoustic Input no ka wehewehe piha ʻana o kēia pae hōʻailona.
ʻO ka Sensitivity e pili ana i ka ratio o ke kaomi hoʻokomo i ka puka uila (voltage a i ʻole kikohoʻe).No nā microphones analog, e ana mau ʻia ka ʻike ma ka mV/Pa, a hiki ke hoʻololi ʻia ka hopena i kahi waiwai dB e:
ʻAʻole ʻoi aku ka maikaʻi o ka naʻau o ka microphone.ʻO ke kiʻekiʻe o ka naʻau o ka microphone, ʻoi aku ka liʻiliʻi o ka palena ma waena o kona pae puka a me ka pae puka kiʻekiʻe ma lalo o nā kūlana maʻamau (e like me ke kamaʻilio ʻana, etc.).I loko o nā noi kokoke (kūkākūkā pili), ʻoi aku ka maʻalahi o nā microphones koʻikoʻi i ka distortion, ʻo ia ka mea e hōʻemi pinepine ai i ka laulima holoʻokoʻa o ka microphone.
