A system for generating a virtual engine sound may include a server having information on at least one review of the virtual engine sound, and a virtual engine sound generator to generate “my sound” by tuning the virtual engine sound based on information on customized design settings, to update a preset driver emotion model for each emotion evaluation area of the virtual engine sound, based on the information on the at least one review of the virtual engine sound, which is received from the server, and to update the virtual engine sound based on the “my sound” and the driver emotion model updated for each emotion evaluation area.

Methods and devices for repelling mosquitoes may operate by generating the sounds of fore and hind pairs of dragonfly wings, which may be dragonfly wing beat sounds. Such sounds may be generated using digital or analog circuitry. The digital sounds may be recordings of synthesized or enhanced sounds of dragonfly wings beating. The device may take the form of a button that may be worn or otherwise carried by a user.

An electrically or partially electrically driven vehicle has a system (1) for active sound design. Active sound design sounds emitted by one or more loudspeakers (5) are modified depending on the driver type and/or depending on the current driving style. The system (1) has at least one sensor for recording measurement parameters (2) that permit a classification of a current driving style and/or a driver type of a driver of the vehicle. The device (1) has a classification device (3) that is configured to determine the current driving style and/or driver type of the driver of the vehicle based on the measurement parameters (2) recorded by the at least one sensor. The system (1) has a sound control system for controlling and modifying the sounds emitted by the loudspeakers (5) based on the current driving style and/or driver type classified by the classification device (3).

A vehicle approach notifying device for notifying the approach of a vehicle by causing a loudspeaker to output a warning sound includes: a storage that stores a predetermined threshold of sound pressure; and a controller that: (i) causes a loudspeaker disposed outside a cabin of the vehicle to output the warning sound at a first sound pressure determined in accordance with a speed of the vehicle when a sound pressure of the warning sound acquired by a microphone disposed outside the vehicle is less than or equal to the predetermined threshold; and (ii) causes the loudspeaker to output the warning sound at a sound pressure lower than the first sound pressure when the sound pressure of the warning sound acquired by the microphone exceeds the predetermined threshold.

An audio device being a mobile terminal includes: a display a touch panel that is that is provided on a surface of the display; a display controller that causes a second display area including the information related to the sorting destination to be superimposed and displayed on a first display area provided within a screen and including a list of music of the sorting source; an accepting unit that accepts, via the touch panel, the user operation of selecting music to be registered in the sorting destination from the sorting source and the user operation of selecting the sorting destination, in a state in which the superimposed display is maintained by the display controller; and a music sorting unit that adds the music to the sorting destination on the basis of the user operation.

The invention relates to the technologies used in simulating the sounds reproduced by the exhaust system or the burnt gas exhaust system of a vehicle engine. Method of simulating the vehicle engine sounds reproduced by the burnt gas exhaust, characterized in that the recorded or synthesized sound templates are loaded into the electronic control unit located in the vehicle and connected to its CAN circuits, and the recorded sound templates (modified depending on the CAN circuits information) are reproduced through at least one speaker that is part of the acoustic device connected with the electronic control unit. Also, a system for simulating the vehicle engine sounds reproduced by the burnt gas exhaust system is described. The technical result consists in providing high accuracy in generating and simulating of specific vehicle engine sounds reproduced by the burnt gas exhaust system.

A method and an apparatus for audio signal processing selection are provided. In the method, multiple audio signal processing operations are performed on a synthesized audio signal to generate multiple processed audio signals, the audio signal processing operations are evaluated according to the comparison results between the processed audio signals and the primary signal, and the audio signal processing operation corresponding to a designated application and the designated audio output mode is selected according to the evaluation result of the audio signal processing operations. The synthesized audio signal is generated by adding a secondary signal into a primary signal. The signal processing is related to remove the secondary signal from the synthesized audio signal. Those processed audio signals are used by the designated application at the designated audio output mode. The comparison result is related to signal similarity. The evaluation result is related to the highest signal similarity.
