Abstract:
A method, system, and apparatus for noise cancelation is disclosed herein, which may be used in a wireless unit (WU) and a headset wirelessly connected to the WU. The WU may include a processor, a memory, a user interface, internal microphones and internal speakers. The headset may include microphones and speakers. The WU may receive an ambient noise from a headset microphone, which may generate a signal based on the ambient noise. The WU processor may then calculate an estimate of the ambient noise based on the signal, calculate an inverse of the estimated ambient noise based on the estimate of the ambient noise, cancel the estimated ambient noise from an audio output signal based on the application of the inverse of the estimated ambient noise, and send the audio output signal wirelessly to the speakers of the headset or the audio output signal to the speakers of the WU.

Claim (Index 5):
A method of performing noise cancellation in a system, wherein the system includes a wireless unit (WU), wherein the WU includes a processor, a memory, a user interface, and one or more internal speakers, and a headset wirelessly connected to the WU, wherein the headset and includes one or more speakers and a microphone, the method comprising:\n receiving, by the processor and the user interface, a first user input selecting a microphone of the headset; receiving, at the microphone of the headset, an ambient noise; generating, by the microphone of the headset, a signal based on the ambient noise; receiving, wirelessly, and storing, by the memory, the signal; receiving, by the processor and the user interface, a second user input setting a scaling factor; calculating, by the processor of the WU, an estimate of the ambient noise based on the signal scaled by the scaling factor; further calculating, by the processor of the WU, an inverse of the estimated ambient noise based on the estimate of the ambient noise; canceling, by the processor of the WU, the estimated ambient noise from an audio output signal based on an application of the inverse of the estimated ambient noise; and sending, by the processor of the WU, the audio output signal to one or more speakers of a headset or the one or more internal speakers of the WU.
