A wearable two-way communication audio device includes a first microphone that provides a first microphone signal, a second microphone that provides a second microphone signal, and a third microphone that provides a third microphone signal. The device also includes one or more processors that are configured to process the first microphone signal and the second microphone signal to form a first beamformed signal. The one or more processors compare energy in the first beamformed signal to energy in the first microphone signal, and, if energy in the first beamformed signal exceeds energy in the first microphone signal, then the one or more processors mix the first microphone signal and the third microphone signal to provide a mixed signal. The one or more processors may also generate a voice output signal for transmission to a far end recipient using the mixed signal.

Wearable audio devices with enhanced voice pickup

Aspects of the present disclosure provide techniques, including devices and system implementing the techniques, to provide feedback to a user of an event when the user is wearing a wearable device. For example, the wearable device may provide high quality noise canceling audio playback to the user, lowering the user's situation awareness. The techniques include measuring ambient sound using two or more microphones on the wearable device. The measured ambient sound is used to determine a related event worth relaying to the user. Based on the location attribute and sound properties, the nature and/or classification of the event may be ascertained using pattern recognition algorithms according to user threshold settings. Insignificant events that the user prefers to ignore will be ruled out by the algorithm. Upon determining the event that merits the user's attention, the wearable device provides feedback to the user indicating the nature and location of the event.

Hearing augmentation and wearable system with localized feedback

A wind noise reduction system including a beamformer, a comparator, and a voice mixer is provided. The beamformer may be an MVDR beamformer, and generates a beamformed signal based on a first microphone signal and a second microphone signal. The comparator generates a comparison signal based on the beamformed signal and a wind microphone signal. The comparison signal may be further based on a beamformed energy level of the beamformed signal and a wind energy level of the wind microphone signal. The voice mixer generates an output voice signal based on the beamformed signal, the wind microphone signal, and the comparison signal. The wind noise reduction system may further include a wind microphone corresponding to the wind microphone signal. The wind microphone may be arranged on a portion of a wearable audio device configured to be seated in a concha of a wearer.

Input selection for wind noise reduction on wearable devices

An audio device with a body configured to be worn on or abutting an outer ear of a user, wherein the body is configured to contact at least one of the outer ear and the portion of the head that abuts the outer ear, at two separate spaced contact locations, and wherein the body is compliant at a body portion that defines one of the contact locations. The device also has an acoustic module carried by the body and configured to locate a sound-emitting opening anteriorly of and proximate the user's ear canal opening when the body is worn on or abutting the ear of the user.

Audio device

Various implementations include approaches for sound enhancement in far-field pickup. Certain implementations include a method of sound enhancement for a system including microphones for far-field pick up. The method can include: generating, using at least two microphones, a primary beam focused on a previously unknown desired signal look direction, the primary beam producing a primary signal configured to enhance the desired signal; generating, using at least two microphones, a reference beam focused on the desired signal look direction, the reference beam producing a reference signal configured to reject the desired signal; and removing, using at least one processor, components that correlate to the reference signal from the primary signal.

Adaptive beamformer for enhanced far-field sound pickup

Systems and methods of treating meibomian and sebaceous gland dysfunction. The methods include reducing oxygen concentration in the environment of one or more dysfunctional meibomian and sebaceous glands, thereby restoring a hypoxic status of one or more dysfunctional meibomian and sebaceous glands. The reducing of the oxygen concentration is accomplished by restricting blood flow to the one or more dysfunctional meibomian and sebaceous glands and the environment of one or more dysfunctional meibomian sebaceous glands. The restricting of the blood flow is accomplished by contracting or closing one or more blood vessels around the one or more dysfunctional meibomian or sebaceous glands. The methods also include giving local or systemic drugs that lead to the generation of hypoxia-inducible factors in one or more dysfunctional meibomian and sebaceous glands.

System and method for treating meibomian gland dysfunction

A wind noise reduction system includes a delay and sum (DAS) beamformer, an MVDR beamformer, a wind detector, a GEV beamformer, and a fixed voice mixer. The DAS beamformer generates a first voice signal based on a first and second microphone signal. The MVDR beamformer generates a second voice signal based on the first and second microphone signals. The GEV beamformer generates a wind array voice signal based on the first and second microphone signals and an accelerometer signal. The wind detector generates a wind detection signal based on the first voice signal and the second voice signal. The fixed voice mixer generates an output voice signal based on a microphone array voice signal, the wind array voice signal, and the wind detector signal. If high winds are detected, the output voice signal includes elements of the wind array voice signal based in part on the accelerometer signal.

Audio processing for wind noise reduction on wearable devices

Aspects of the present disclosure provide techniques, including devices and system implementing the techniques, to provide feedback to a user of an event when the user is wearing a wearable device. For example, the wearable device may provide high quality noise canceling audio playback to the user, lowering the user's situation awareness. The techniques include measuring ambient sound using two or more microphones on the wearable device. The event is determined based on the measured ambient sound. A location attribute of the event is determined. A deep learning algorithm may be used to identify the nature and/or classification of the event and rule out events that the user prefers to ignore. Upon determining the event that merits the user's attention, the user is provided feedback of the determined event and the location attribute, the feedback indicating the nature and location of the event.

Ear tip

Headset

An ear tip for an earpiece including a body having first and second ends, an inner wall extending between the first and second ends to define a hollow passage to conduct sound waves, and an outer wall connected to the inner wall of the body at the first end and tapering away from the inner wall toward the second end. The ear tip further includes first and second electrically conductive elements arranged on an outer surface of the deformable outer wall.
