The technology described herein is generally directed towards the use of spatial audio to provide directional cues to assist a user in looking in a desired direction in a user perceived environment, which can be a real-world or a virtual environment. Location data for a user in three-dimensional space can be obtained. A direction of view of the user within the user-perceived environment is determined. Spatial audio can be output that is perceived as coming from a position within the user-perceived environment, such as to provide directional cues directed to changing the direction of view of the user to a different view. The spatial audio can provide prompts to the user to adjust his or her vision towards the desired direction, for example. The user's location and direction of view can be mapped to audio that is relevant to the user's direction of view when at that location.

Various implementations disclosed herein include devices, systems, and methods that that modify audio of played back AV content based on context in accordance with some implementations. In some implementations audio-visual content of a physical environment is obtained, and the audio-visual content includes visual content and audio content that includes a plurality of audio portions corresponding to the visual content. In some implementations, a context for presenting the audio-visual content is determined, and a temporal relationship between one or more audio portions of the plurality of audio portions and the visual content is determined based on the context. Then, synthesized audio-visual content is presented based on the temporal relationship.

To enable listening to audio in a more suitable mode without any complicated operation even in a situation in which the user's state or situation successively changes. An information processing device including: a recognition processing unit that recognizes a user's state in accordance with a detection result of a predetermined state or situation; and an output control unit that controls audio output from a predetermined output unit on the basis of a function map, which is selected in accordance with a predetermined condition, in which a setting related to control of the audio output is associated with each of a plurality of candidates for the user's state, and the recognized user's state.

Disclosed embodiments may relate to systems and methods for monitoring and/or mapping noise data from a plurality of noise monitoring devices. In some embodiments, the plurality of noise monitoring devices may include hearing protection devices configured to detect noise, and typically may communicate such noise data (which may also include location) so that the noise data can be pooled. The pooled noise data from the plurality of noise monitoring devices may then be used to the benefit of one or more of such noise monitoring devices.

A system for mobile device localization is provided with a primary device. The primary device is configured to transmit a first signal at a first transmission power level to a secondary device and to receive a response signal that is indicative of a signal strength indicator of the first signal as received by the secondary device. The primary device is further configured to determine a second transmission power level based on the signal strength indicator; transmit a second signal at the second transmission power level to the secondary device; and to determine a distance between the primary device and the secondary device based on a filtered transmission power level value.

A hearing device is physically adjusted to suit a hearing device wearer. A position sensor of the hearing device is used to ascertain a characteristic measure of a current actual wearing position of the hearing device. The characteristic measure of the actual wearing position is then taken as a basis for ascertaining a discrepancy between the actual wearing position and a prescribed desired wearing position. On the basis of this discrepancy, an instruction is output to the hearing device wearer to adjust the receiver connector based on the ascertained discrepancy.

A system includes at least one earpiece having at least one sensor, at least one speaker, and at least one processor capable of ascertaining a desired position for a user's head in order to guide the user as to the desired position for the user's head. A method it determining a current orientation of a user's head, calculating a desired position for the user's head in relation to the current orientation of the user's head, creating an audio signal containing instructions to guide the user as to the desired position for the user's head, and transmitting the audio signal to a user's ears.

When a hearing device is determined to be capable of being of being paired with each of a plurality of appliances, a one of the plurality of appliances is automatically selected for an attempted pairing with the hearing device. The one of the plurality of appliances is selected using priority information that has been associated with each of the plurality of appliances. One the one of the plurality of appliances has been selected; the hearing device is caused to automatically attempt to pair with the selected one of the plurality of appliances.

A headset includes a wearable body, first and second earphones extending from the wearable body, controls for controlling an external communication/multimedia device wirelessly, a microphone for picking up vocal data from a user of the headset system and a signal processing unit. The signal processing unit includes circuitry for processing the vocal data into a distinctly audible vocal feedback signal, circuitry for enhancing the vocal feedback signal thereby producing an enhanced vocal feedback signal and circuitry for mixing the enhanced vocal feedback signal with audio signals originating from the external communication/multimedia device, thereby producing a mixed output signal and then sending the mixed output signal to the user via the earphones. The external communication/multimedia device comprises a vocal command application and the headset further comprises a vocal command control for sending vocal commands to the external communication/multimedia device and to the vocal command application.

A vehicle selects various sound sources and outputs driving sound based on information received from the navigation system. A database stores sound sources classified as first and second emotions. A controller outputs a landmark name based on a route guidance text and outputs a ratio of the first and second emotions corresponding to the landmark name. The controller selects a first sound source from the sound sources classified as the first emotion based on the first emotion ratio, selects a second sound source from the sound sources classified as the second emotion based on the second emotion ratio and determines first and second playback periods based on the ratios of the first and second emotions. The controller outputs a first sound generated based on the first sound source during the first playback period and a second sound generated based on the second sound source during the second playback period.
