When you take the iPhone away from your face during a call and put it into speakerphone mode (tap the Speaker button), the top microphone is the one that is now active. Since the top microphone is much farther from your mouth than the bottom microphone, the device can assume that what it’s hearing through the top microphone is mostly background noise and that what it’s hearing through the bottom microphone is mostly your voice, and it can invert the noise input and mix that with the voice input to reduce the noise component and make your voice clearer.Īnd now for the surprise.

This makes it easy to speak into the bottom microphone during a call. The microphone on the bottom is the grille to the left of the dock connector port as you look at the front of the iPhone - the grille to the right of the port is a speaker.
