Abstract: An ear cup housing has several reference microphones, an error microphone and a speaker. A processor drives the speaker for acoustic noise cancellation and transparency, by processing the microphone signals, and performs an oversight process by adjusting the reference microphone signals in response to detecting wind noise events and scratch events. In another aspect, the ear cup housing has an outside face that is joined to an inside face by a perimeter and the reference microphones are on the perimeter. Other aspects are also described and claimed.

Abstract: A method performed by an in-ear headphone. Coupled to the in-ear headphone is a first ear tip that is inserted into an ear canal of a user. The method obtains an audio signal from an audio source device paired with the in-ear headphone and uses the signal to drive a speaker of the headphone to output a sound into the ear canal. The method obtains a microphone signal that is responsive to the outputted sound. The method notifies the user to replace the first ear tip with a second ear tip in response to a parameter associated with the microphone signal being less than a threshold.

Abstract: A wireless communication device establishes voice communication between a supported user and a selected remote device supporting another user via a point-to-point wireless ad hoc network link. The device selects a particular remote device, establishes an ad hoc network link with the selected remote device, and communicates voice communication signals with the selected remote device. Selection can be based upon a user interaction with the device which specifies the particular remote device. The user interaction can include interaction with a graphical representation of the particular remote device presented in a graphical user interface. The user interaction can include an audio command received via an audio interface of the device. The device can include one or more headset devices, including a pair of headset devices which can be switched between providing audio signals to a single user to supporting communication between separate users via an ad hoc network link.

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.
