An electronic device receives audio from an audio source and outputs the audio via speakers of the device. While outputting the audio via the speakers, the device senses its surrounding environment, and adjusts its operation, based on the sensed environment, to alert a listener wearing the device. The adjustment may comprise generation of one or more audio, visual, and/or vibration notifications to the listener using the device. A volume of the audio output via the speakers may be adjusted based on the sensed surrounding environment. The device may detect whether a first condition is present in the surrounding environment, decrease the volume when the first condition is detected in the surrounding environment, and increase the volume when the first condition is not detected in the surrounding environment.

During an initialization of a head pose tracker for a spatial audio system, a spatial audio ambience bed is rotated about a boresight vector to align the boresight vector with a center channel of the ambience bed. The boresight is computed using source device motion data and headset motion data. The ambience bed includes the center channel and one or more other channels. An ambience bed reference frame is aligned with a horizontal plane of a headset reference frame, such that the ambience bed is horizontally level with a user's ears. A first estimated gravity direction is fixed (made constant) in the ambience bed reference frame. During head pose tracking, the ambience bed reference frame is rolled about the boresight vector to align a second estimated gravity direction in the headset reference frame with the first estimated gravity direction fixed in the ambience bed reference frame.

A device is discussed, such as the hearing assistance device itself and/or an electrical charger cooperating with the hearing assistance device. The device can have one or more accelerometers and a power control module to receive input data indicating a change in acceleration of the device over time from the one or more accelerometers in order to make a determination to autonomously change a power mode for the hearing assistance device based on at least whether the power control module senses movement of the hearing assistance device as indicated by the accelerometers.

A system, method, and wireless earpieces for implementing a virtual assistant in response to user preferences. User preferences associated with a user of the wireless earpieces are received. Data and information about the user and an environment of the user are automatically captured by the wireless earpieces based on the user preferences. A determination is made whether to provide automatic assistance to the user based on the user preferences utilizing the virtual assistant of the wireless earpieces. The automatic assistance is generated through the virtual assistant of the wireless earpieces utilizing the data and the information. The automatic assistance is communicated to the user through the virtual assistant of the wireless earpieces.

The present disclosure provides an audio output method, including acquiring attribute information and location information of at least one object from an environment in which a user is located; determining, based on the attribute information, at least one piece of audio information that corresponds to the at least one object; determining, based on the location information, a relative spatial relationship between the at least one object and the user; adjusting, based on the relative spatial relationship, an output parameter of the at least one piece of audio information; and outputting, based on the output parameter, the at least one piece of audio information indicative of the location information of the at least one object.

An intercom system provides audio communication between multiple users wearing head-mounted devices (HMDs). In an embodiment, the intercom system determines a first location of a first HMD of a first user. The intercom system determines a second location of a second HMD of a second user. The intercom system receives audio of the first user from a microphone of the first HMD. The intercom system determines a volume level of the audio at the second location using at least the first location and the second location. The intercom system transmits the audio to the second HMD responsive to determining that the volume level is less than a threshold volume. The intercom system may also selectively transmit audio based on gaze direction of a user. Additionally, the intercom system may generate a transcript of audio input by users.

Various embodiments include a directional awareness audio communication system and method. The system may include remote speaker/transmitting device(s) and listener/receiving device(s). The speaker/transmitting device(s) may send real-time location information with audio or separate from the audio to the listener/receiving device(s). The listener/receiving device(s) use the speaker/transmitting device(s) location information relative to the listener/receiving device location and orientation to perform audio processing on the transmitted audio signal. The listener/receiving device(s) provide the processed audio signal in stereo (i.e., at least two speakers such as left and right headphones, vehicle speakers, control center speakers, surround sound speakers, etc.) to a user of the listener/receiving device. The listener/receiving device(s) provides a warning and outputs standard audio if the real-time location information of the speaker/transmitting device(s) is unavailable or unreliable. In various embodiments, the listener device provides haptic and/or visual feedback of the speaker device location with respect to the listener device location.

Examples described herein involve validating motion of a microphone during calibration of a playback device. An example implementation involves a mobile device detecting, via one or more microphones, audio signals emitted from one or more playback devices as part of a calibration process. After the one or more playback devices emit the audio signals, the mobile device determines whether the detected audio signals indicate that sufficient horizontal translation of the mobile device occurred during the calibration process. When the detected audio signals indicate that insufficient horizontal translation occurred, the mobile device displays a prompt to move the mobile device more while the one or more playback devices emit one or more additional audio signals as part of the calibration process. When the detected audio signals indicate that sufficient horizontal translation occurred, the mobile device calibrates the one or more playback devices with a calibration based on the detected audio signals.

Devices, systems and processes for providing an adaptive audio environment are disclosed. For an embodiment, a system may include a wearable device and a hub. The hub may include an interface module configured to communicatively couple the wearable device and the hub and a processor, configured to execute non-transient computer executable instructions for a machine learning engine configured to apply a first machine learning process to at least one data packet received from the wearable device and output an action-reaction data set and for a sounds engine configured to apply a sound adapting process to the action-reaction data set and provide audio output data to the wearable device via the interface module. The audio output data may be utilized by the wearable device to provide an adaptive audio environment.

Determination of a set of acoustic parameters for a headset is presented herein. The set of acoustic parameters can be determined based on a virtual model of physical locations stored at a mapping server. The virtual model describes a plurality of spaces and acoustic properties of those spaces, wherein the location in the virtual model corresponds to a physical location of the headset. A location in the virtual model for the headset is determined based on information describing at least a portion of the local area received from the headset. The set of acoustic parameters associated with the physical location of the headset is determined based in part on the determined location in the virtual model and any acoustic parameters associated with the determined location. The headset presents audio content using the set of acoustic parameters received from the mapping server.
