Title: Binaural reproduction device and program
Inventor: SUGIMOTO TAKEHIRO
IPC: H04S7/00
Filed: 2020-08-18
Abstract: To provide a binaural reproduction device that can reflect the angle dependence of the radiation characteristics of a sound source using an existing head-related transfer function.SOLUTION: A propagation path derivation unit derives a propagation path from a sound source to the ear on the basis of the position of the sound source, the shape of the listener's head, and the position of the listener's ear. A sound source radiation direction determination unit determines the radiation direction from the sound source to the ear on the basis of the propagation path. A sound source database outputs a sound signal having acoustic characteristics corresponding to the determined radiation direction, and a head-related transfer function selection unit selects a transfer function on the basis of the direction from the center of the listener's head specified by the position of the center of the listener's head and the position of the sound source, to the sound source. A reproduction signal generation unit generates a reproduction signal for the ear on the basis of the output sound signal and the transfer function selected by the head-related transfer function selection unit.SELECTED DRAWING: Figure 1

Title: vehicle
Inventor: TAKAHASHI AYUMU
IPC: F02M26/33
Filed: 2020-08-21
Abstract: To protect an intake pipe or the like of an engine while suppressing the increase in size of a pump.SOLUTION: When a first flow path valve and a second flow path valve are open, an exhaust gas recirculation device is controlled so that an amount of recirculation of engine exhaust to intake air is limited compared to a case where at least one of the first flow path valve and the second flow path valve is closed. Consequently, when a maximum flow rate of cooling water flowing through a third branch flow path is small, it is possible to suppress the lack of cooling performance by a heat exchange unit for exhaust flowing through a connection pipe, to suppress the supply of high-temperature exhaust to an intake pipe of an engine. As a result, it is possible to protect the engine, especially the intake pipe, while suppressing increase in size of a pump.SELECTED DRAWING: Figure 3
