Question for the noise cancelling Microphones

[Norbert69]

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!

You are probably much better off posting this query at Gearslutz. They are far more geared towards such things than a bunch of old fart Beatles/Byrds/Yes/Deep Purple/etc, fans.

You might, also, want to post on TalkBass. In particular, there are a few superb engineers there, such as agedhorse (engineer for Mesa Engineering, also a sound engineer for decades) and Bob Lee (QSC).
