Abstract:
A headphone has a driver, an internal microphone, an accelerometer, and an external microphone. An audio processor analyzes signals to detect wind noise. Gain of lower frequencies is reduced relative to higher frequencies, in a first filter that is operating on an audio signal from the external microphone in a feedforward path, responsive to detecting increased wind noise. A second filter in an audio signal feedback path may be adjusted to compensate for the gain change in the first filter that may mitigate occlusion effect. Outputs of the feedforward path in the feedback path are combined to produce an audio signal for the driver. The driver produces sound in the aural canal that has transparency with reduced wind noise, relative to sound external to the headphone. Other aspects are also described and claimed.

Claim (Index 3):
The audio processing system of  claim 1 , wherein to mitigate an occlusion effect that is caused by positioning of the headphone relative to the aural canal, the audio processor is to configure the second filter in the feedback path to produce an audio signal of the feedback path that reduces booming of the user's voice in the aural canal through the bone conduction.
