Question about noise cancelling Microphones

Postby RonyBelt » 11 Jul 2017, 20:56

I have constructed a noise canceling Microphone utilizing EK-23133-A21 single supply yet I am experiencing issues understanding the noise canceling Circuit IC.

It contains the EK-23133-A21, (Frequency-100Hz ~ 6kHz - -54dB ±3dB @ 74dB SPL) with 1.3v.

Can anyone 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

This will save you time on writing such a complex and voluminous written work. Real writers work here who are able to cope with topics of any complexity.. Then the other hosts do not receive packets from the host.
