    摘要: Microphones are provided at an air inlet of the engine and a vehicle-cabin-side wall surface of an engine room, and engine sounds are picked up. The engine sound is processed by a signal processing section, and the processed engine sound is output from a speaker provided in a vehicle cabin. The signal processing section is provided with a filter which simulates a sound insulation characteristic of the vehicle cabin and a transformation section for processing the engine sound according to driving condition. A spectrum transformation characteristic of the transformation section is determined according to values detected by a vehicle speed sensor, an engine speed sensor, and an accelerator depression sensor, and a spectrum of the engine sound is transformed by means of specification of the spectrum transformation characteristic, thereby enhancing an engine sound.

    摘要: An inattention determining device includes range changing unit and inattention determining unit. When a curve detection result is output from curve detector, the range changing unit changes a first predetermined range to a second predetermined range by the predetermined amount in the curve direction before a turning direction of an acquisition result is changed in the curve direction of the curve detection result. The inattention determining unit determines whether or not a driver is in an inattention state on the basis of the second predetermined range.

    摘要: A three-dimensional sound reproducing apparatus is configured by cascading a sound field effect adding unit and a crosstalk canceling unit. The sound field effect adding unit adds a predetermined three-dimensional sound field effect to an input audio signal, thereby generating audio signals respectively corresponding to left and right channels. The crosstalk canceling unit performs a calculation process on the audio signals of the two channels so that, when the audio signals are respectively generated by two loudspeakers positioned in front of a listener, the audio signals reach the left and right ears of the listener without producing crosstalk. The resulting audio signals are supplied to the loudspeakers, respectively. A sound image localizing unit receives two-channel audio signals which are obtained by encoding a center-channel audio signal, a left-channel audio signal, a right-channel audio signal, and a nonlocalization audio signal, and outputs two-channel audio signals in which sound images are to be respectively localized at virtual loudspeakers.
