Question for the noise cancelling Microphones

[trixter]

I have developed a noise canceling Microphone utilizing WP-23501-000 single supply yet I am experiencing issues understanding the noise canceling Circuit IC.

It contains the WP-23501-000, (Frequency-100Hz ~ 6kHz - -54dB ±3dB @ 74dB SPL) with 1.3v.

Can you please help me the detailed of noise canceling frequency?

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

Sorry trixter, but this is neither a HiFi related question nor the right forum for it.

Maybe diyaudio.com is the right place. Or maybe not, I'm unsure.
