A roof of a vehicle includes a panel, and at least one audio device selected from the loudspeakers and the actuators, and when the at least one audio device is an actuator, it is located on the panel, the panel being capable of vibrating.

A sound processing method includes obtaining an image of an acoustic space, setting a plane in the acoustic space using the image, setting a virtual speaker in the image of the acoustic space, calculating sound pressure distribution to the plane using characteristics of the virtual speaker, and overlapping the sound pressure distribution and the image of the plane.

A sound data processing device includes: a sound data acquisition unit configured to acquire first sound data that is data about a sound whose sound image is localized in a cabin of a vehicle; an object specifying unit configured to specify an attention object that is an object to which an occupant of the vehicle directs attention; a sound data processing unit configured to generate second sound data that is data about the sound for which a sound relating to the attention object is emphasized in comparison with the first sound data; and a sound data output unit configured to output the second sound data to an output device that outputs a sound to the occupant.

A computer-based method for modifying a sound source. The method includes: accessing, by an acoustic processing facility including at least one processor, a multi-dimensional sound signature of an acoustic environment, wherein the multi-dimensional sound signature comprises a time-based sound reflection sequence for the acoustic environment; and receiving sound source data from a sound input device in a recording space. The method further includes modifying, by the acoustic processing facility, the sound source data based at least in part on the multi-dimensional sound signature to generate a modified sound source data; and recording the modified sound source data on a sound recording device.

The method includes activating a sound emitter.

Proposed is a noise avoiding method for a space monitoring apparatus using a sound signal and, more specifically, is a technology that allows the space monitoring apparatus, which uses a sound signal to monitor a spatial condition, to avoid noise in a space to be monitored to correctly determine the spatial condition.

A reproduction apparatus that realizes reproduction of which sound leakage is small with use of a speaker installed near a head, and a method and a program thereof are provided. The reproduction apparatus is used in a seat. The reproduction apparatus includes: at least two speakers; an acquisition unit that acquires, from a predetermined sound source, an acoustic signal of which sound is emitted by the reproduction apparatus; and a control unit that controls the acoustic signal acquired by the acquisition unit such that reproduction sound is only transmitted to a first seat and the reproduction sound is not transmitted to a second seat, the speakers each emit sound of the acoustic signal controlled by the control unit, and the speakers are disposed so as to be closer to an ear of a user that sits in the first seat than to the second seat.
