The invention provides a lighting device for determining and conveying an intelligibility of an audio signal, wherein the audio signal comprises a plurality of occurrences of a repeating audio feature, wherein each occurrence of the repeating audio feature comprises a respective value of an acoustic characteristic, wherein the lighting device comprises: a light source; a microphone for detecting the audio signal; a processor configured to: receive the audio signal from the microphone, determine a baseline value based on said audio signal, determine a positive intelligibility of the audio signal if the last occurrence of the repeating audio feature comprises a respective value of the acoustic characteristic being at least equal to the baseline value, or determine a negative intelligibility of the audio signal if the last occurrence of the repeating audio feature comprises a respective value of the acoustic characteristic being less than the baseline value, and control the light source to convey the determined positive and/or negative intelligibility of the audio signal via a lighting characteristic.

A headset generates an acoustic map that is a visual representation of sound pressure of sound within a local area. The acoustic map is displayed as a virtual object that is overlaid onto visual content being presented by the headset. Sound is adjusted in accordance with a command. The acoustic map is updated based on the adjusted sound, and the adjusted sound is presented and the updated acoustic map is presented.

Embodiments herein relate to ear-worn devices that can track exposure to hearing degrading conditions and/or provide notifications or warnings regarding the same. In an embodiment, an ear-worn device is included having a control circuit, a microphone in electrical communication with the control circuit, an electroacoustic transducer for generating sound in electrical communication with the control circuit, and a power supply circuit in electrical communication with the control circuit, wherein the ear-worn device is configured to track exposure to hearing degrading conditions over time via at least one of the microphone and a sensor package and wherein the ear-worn device is configured to store data regarding the tracked exposure. Other embodiments are also included herein.

In general, user interfaces for controlling a plurality of multimedia players in groups are disclosed. According to one aspect of the present invention, a user interface is provided to allow a user to group some of the players according to a theme or scene, where each of the players is located in a zone. When the scene is activated, the players in the scene react in a synchronized manner. For example, the players in the scene are all caused to play a multimedia source or music in a playlist, wherein the multimedia source may be located anywhere on a network. The user interface is further configured to illustrate graphically a size of a group, the larger the group appears relatively, the more plays there are in the group.

Example techniques relate to playback based on acoustic signals in a system including a first network device and a second network device. A first network device may detect a presence of a user using a camera and/or infrared sensors. The first network device sends, in response to detecting the presence of the user, a particular signal via the first network interface. The second network device receives data corresponding to the particular signal and plays back an audio output corresponding to the particular signal.

Disclosed are an electronic device and a control method. The electronic device comprises a communication interface for communicating with an external apparatus in a UWB manner, a microphone, a camera, a sensor, a display, and a processor, wherein the processor obtains distance information and angle information with respect to the external apparatus, on the basis of data received from the external apparatus, obtains photographing direction information, on the basis of a detected direction of the camera, identifies the external apparatus, on the basis of the acquired photographing direction information, distance information, and angle information, controls the microphone or communication interface to acquire an audio signal, on the basis of a distance from the external apparatus, and controls the display to display a UI indicating the amplitude of the acquired audio signal, together with a displayed image.

A wireless headphone system is provided. The system includes a first earbud, a second earbud, and one or more controllers. The first earbud is programmed to wirelessly communicate with a mobile device to playback an audio output in a first ear for a user. The second earbud is programmed to wirelessly communicate with the mobile device to playback the audio output in a second ear from the user. The at least one controller is programmed to determine whether the first earbud or the second earbud has been removed from the first ear or the second ear, respectively, and to enable the user to provide a first audio input into a microphone of the first earbud or the second earbud that is removed from the first ear or the second ear, respectively.

Example techniques involve a calibration state variable. An example implementation receives, via a network interface, an indication that the first playback device is calibrated. Based on receiving the indication that the first playback device is calibrated, the example implementation updates a calibration state variable to indicate that the first playback device is calibrated, wherein the calibration state variable is stored in the data storage. The example implementation sends, via the network interface, an indication of the updated calibration state variable to a second device.

Example methods and systems for displaying one or more indications that indicate (i) the direction of a source of sound and (ii) the intensity level of the sound are disclosed. A method may involve receiving audio data corresponding to sound detected by a wearable computing system. Further, the method may involve analyzing the audio data to determine both (i) a direction from the wearable computing system of a source of the sound and (ii) an intensity level of the sound. Still further, the method may involve causing the wearable computing system to display one or more indications that indicate (i) the direction of the source of the sound and (ii) the intensity level of the sound.

A method of operation of a device includes receiving an input signal at the device. The input signal is generated using at least one microphone. The input signal includes a first signal component having a first amount of wind turbulence noise and a second signal component having a second amount of wind turbulence noise that is greater than the first amount of wind turbulence noise. The method further includes generating, based on the input signal, an output signal at the device. The output signal includes the first signal component and a third signal component that replaces the second signal component. A first frequency response of the input signal corresponds to a second frequency response of the output signal.
