Question for the noise cancelling Microphones
Posted: Fri Sep 22, 2017 1:03 pm
First off, as a new user hello to everyone!
Let me get straight to the point. I might ask help about noise canceling Microphones.
I have assembled a noise canceling Microphone using EK-28522-C25 single supply yet
( for an example as I found here https://www.icrfq.com/part/351-EK_28522_C25.html )
I am experiencing issues understanding the noise canceling Circuit IC.
It contains the EK-28522-C25, (Frequency-100Hz ~ 6kHz - -54dB ±3dB @ 74dB SPL) with 1.3v.
Sensitivity W/M 54db±3dB-74dB SPL between 65db±5dB-85dB
Air pumping Capacity 7mm³ and fo 480Hz
Frequency Range 450-8000Hz
Maximum Sine Power 10mW
SPL 110dB max sine power
Can anyone please help me the detailed of noise canceling frequency?
Thanks in advance!
