A vehicle sound generation device includes a controller that generates a sound signal representing a sound and sets the localization of the sound, and left and right front speakers and left and right rear speakers that output sounds corresponding to the sound signals for which localization has been set by the controller, in which the controller sets the localization of the sounds based on the change amounts (such as the pitch rate, the torque change amount, the roll rate, and steering angular speed) per unit time of the physical quantities correlated with a driving operation by the driver of the vehicle so that the sound image of at least part (low frequency component) of frequency components of the sound is located toward the wheel where the ground load is increasing according to the driving operation.

An audio spot forming system (S) is an audio spot forming system which transmits an alert sound to a vehicle traveling on a road, the audio spot forming system including a first parametric speaker (1) configured to emit a sideband wave, and a second parametric speaker (2) configured to emit a carrier wave, in which the sideband wave and the carrier wave are caused to intersect with each other on the road to form an audio spot.

Disclosed is a food texture presentation apparatus 1 including a synthesizer 13 that acquires, with reference of a recipe of a food product selected, audio signals of mastication sounds of ingredients contained in the food product from a database 15 and synthesizes the acquired audio signals of the ingredients into an audio signal of a food texture to be presented, and a presentation unit 14 that uses the synthesized audio signal to present the food texture of the food product.

Provided is an active acoustic control program that can reduce noise in a vehicle interior irrespective of the vehicle type, due to being installed in a device that is easily available to anyone. This active acoustic control program is downloaded using a communicator that transmits and receives data to and from a server, and this program causes a computation process device to execute a process for generating a control signal that causes a canceling sound to be outputted from a speaker provided in an interior of a vehicle in order to reduce noise in the vehicle interior. Said program is provided with an adaptive notch filter that processes a reference signal as an adaptive signal to generate a control signal, and a control filter coefficient update unit that continuously updates a filter coefficient of the adaptive notch filter so that an error signal is minimized.

This information processing device comprises: a control unit which receives an input of information indicating one or more timings in a playback time of a piece of music, and generates a file including information pertaining to a timbre control performed from each of the one or more timings; and a transmission unit which transmits an audio signal of the piece of music and the information pertaining to the timbre control in the file to a device which outputs a synthesized sound of the playback sound of the piece of music and the playing sound of a musical instrument.

A sound generation apparatus for an electrification vehicle and a method of use thereof are provided. In example embodiments, the sound generation apparatus receives driving information, determines a driving situation based on the driving information, designs an acceleration sound when the driving situation is determined as an acceleration situation, or designs a cornering sound when the driving situation is determined as a cornering situation, and plays and outputs the acceleration sound or the cornering sound.
