SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, MEASUREMENT METHOD, AND MEASUREMENT DEVICE |
摘要 |
Provided is a signal processing device including an input unit inputting a sound collection signal of a sound of a user collected by user-surrounding microphones with inward directivity in a reproduction environment, an acoustic-signal processing unit obtaining a reproduction signal of a sound field in a measurement environment by performing a process on the sound collection signal based on a transfer function measured based on a result of sequential emission of predetermined sounds from speakers at positions set on a first closed surface with outward directivity in the measurement environment and collection of the sounds with microphones at positionst on a second closed surface with outward directivity in the measurement environment and indicates how the sounds are transferred to the positions on the second closed surface, and a sound-emission control unit causing user-surrounding speakers to emit sound based on the reproduction signal with inward directivity in the reproduction environment. |
