Abstract:
Embodiments may find applications to ambient noise attenuation in cell phones, for example, where a second microphone is placed at a distance from the voice microphone so that ambient noise is present at both the voice microphone and the second microphone, but where the user's voice is primarily picked up at the voice microphone. Frequency domain filtering is employed on the voice signal, so that those frequency components representing mainly ambient noise are de-emphasized relative to the other frequency components. Other embodiments are described and claimed.

Claim (Index 21):
The system of  claim 19 , further comprising first and second microphones, wherein the first microphone is configured to provide the first reference signal based on primarily speech information, and wherein the second microphone is configured to provide the second reference signal based on primarily ambient noise information.
