A method for adjusting an audio transmission when a user of the system is being spoken to by another person includes receiving audio signals representative of sounds from an environment of the user captured by at least one microphone; determining at least from the received audio signals that the another person is speaking to user; and subject to the user being spoken to by the another person, adjusting the audio transmission to the user and signaling to the user that the user is being spoken to.

An air purifier includes a cylindrical filter configured to filter pollutants included in air that enters the air purifier, and a plurality of speakers coupled to a circumference of an outer surface of the cylindrical filter. A communication interface is configured to obtain information from an external device, and a processor is configured to control the plurality of speakers to output an audio signal corresponding to the information.

An electronic device having circuitry, which is configured to estimate a distraction level of an audio object stream, and to modify the audio object stream based on the estimated distraction level to obtain a modified audio object stream.

A system for automatically adjusting a volume of a loudspeaker includes a loudspeaker and a processor. An infrared sensor, which generates a sensing signal when sensing IR radiation from a heat-radiating source, is disposed on the loudspeaker. The sensing signal provides a size information commensurate with a size of the heat-radiating source. The processor receives a plurality of the sensing signals at different time points to obtain a plurality of corresponding size information, realizes a change of distance between the heat-radiating source and the loudspeaker according to a change of the size information, and generates a volume-adjusting signal according to the change of distance between the heat-radiating source and the loudspeaker. The volume-adjusting signal is transmitted to the loudspeaker to adjust the volume of the loudspeaker accordingly.

An apparatus comprising means including circuitry configured for: applying equalization to a sub-set of a plurality of spatial sound sources, included in a sound scene, to modify the sound scene, wherein spatial sound sources are associated with respective locations in the sound scene, wherein equalization includes frequency-dependent level adaptation, and wherein the sub-set includes multiple spatial sound sources but does not include all of the plurality of spatial sound sources.

A system for facilitating configuration of an audio system tests the existing audio system configuration by playing reference audio clips of various different genres of programming, the audio of which is received by a microphone of a remote control device or other handheld mobile device at various different listening points in the room. The system then compares the audio signal representing audio of the reference audio clip received at the microphone to a reference audio signal representing the reference audio clip and determines other audio characteristics. The system then determines, based on the comparison and other characteristics of the room (e.g., furniture layout, room construction materials, wall treatments and current speaker positioning) suggested changes to a configuration of the audio system to increase audio quality of the audio system for playing audio associated with the various different genres of programming.

The invention discloses an electroencephalogram-controlled video input and auditory display blind guiding apparatus and method. The apparatus includes a video acquisition module, an electroencephalogram acquisition module, a processor and an audio playback module. The video acquisition module is connected to the processor, the electroencephalogram module is connected to the processor and configured to acquire an electroencephalogram signal, the audio playback module is connected to the processor, and the processor is separately connected to the video acquisition module, the electroencephalogram acquisition module and the audio playback module. According to the present invention, control of a region of interest in the blind guiding apparatus is achieved by means of the electroencephalogram signal, so that sensing a whole image and sensing details of interest in the image are switched conveniently. A region of interest in a current video is set by using the electroencephalogram, a flexible auditory display resolution and a control method are provided for a user, and the user can sense global information or local detail information of the image with the setting of the region of interest, so that the defect of low auditory display resolution is overcome effectively. The invention can be widely applied to different occasions where blind guiding is required.

When a first condition related to a change in a position of a virtual microphone in a virtual space is satisfied, a residual virtual microphone is placed at a position of the virtual microphone before the change in the position, and residual virtual microphone acquisition sound data whose volume is set on the basis of a distance between the residual virtual microphone and a virtual sound source and current virtual microphone acquisition sound data whose volume is set on the basis of a distance between the virtual microphone after the change in the position and the virtual sound source are outputted to a speaker such that an output level of the residual virtual microphone acquisition sound data is gradually decreased and an output level of the current virtual microphone acquisition sound data is gradually increased.

There is provided a system for generating instructions for adjustment of vehicle sub-system(s) according to an analysis of a computed six degrees of freedom (6 DOF) of vehicle occupant(s), comprising: hardware processor(s), and a non-transitory memory having stored thereon a code for execution by the at least one hardware processor, the code comprising instructions for: obtaining at least one image of a cabin of a vehicle captured by an image sensor, obtaining depth data from a depth sensor that senses the cabin of the vehicle, wherein the at least one image and the depth data depict at least one head of at least one occupant, computing 6 DOF for the at least one head according to the at least one image and depth data, and generating instructions for adjustment of at least one vehicle sub-system according to the computed 6 DOF of the at least one vehicle occupant.

A method performed by a first electronic device that includes a first speaker, the method includes, receiving, via a network, a representation of audio content, while a second electronic device is playing back the audio content through a second speaker, determining that the first electronic device is moving away from the second electronic device, and, in response to determining that the first electronic device is moving away from the second electronic device, using the representation of audio to play back the audio content through the first speaker.
