Main Parameter of electret condenser microphone

1.What is the Noise Cancelling Electret condenser microphone?

A noise cancelling microphone (also known as pressure gradient or close talking) is a directional microphone designed for use close to the talker's mouth. Its directional pattern looks like a figure 8, and is called cosine or bidirectional.

2. The usage of Noise Cancelling Electret condenser microphone:

 Very small noise cancelling microphone

Close talk characteristics effectively reduce ambient noise.
