Patent ID: 7983428

Claim:
A communication device comprising: a wireless adapter at which a wireless headset communicatively connects to the communication device and at which is received a first acoustic input that includes a speech input and a first ambient noise input; a microphone that receives a second acoustic input, which includes a second ambient noise input; a dual-channel adaptive noise canceller that utilizes the second ambient noise input to filter the first ambient noise input out of the first acoustic input to generate an acoustic output that primarily comprises the speech input; logic for evaluating when a distance between the wireless headset and the communication device is less than a preset threshold distance, which distance enables the dual-channel adaptive noise canceller to provide a measurable improvement in a quality of a speech signal within the acoustic output relative to the speech signal within the first acoustic input due to filtering out of ambient noise from the first acoustic input; and logic for activating the dual-channel adaptive noise canceller only when the distance is not less than the preset threshold distance; wherein no ambient noise cancellation is provided via the dual-channel adaptive noise canceller when the wireless headset is less than the preset threshold distance from the communications device.
