    • Provided is a signal processing device including a display control unit for causing a display to display an image corresponding to a specified place, a sound-collection-signal input unit for inputting a sound collection signal of a sound collection unit that collects a user sound produced with microphones surrounding the user, an acoustic-signal processing unit for performing a first acoustic-signal process for reproducing a sound field where the user sound is sensed as if the sound were echoing in the place on the signal input by the sound-collection-signal input unit, based on a first transfer function measured in the place to indicate how a sound emitted on a closed surface inside the place echoes in the place and then is transferred to the closed-surface side, and a sound-emission control unit for causing a sound based on the processed signal to be emitted from speakers surrounding the user.
    • 提供了一种信号处理装置,包括:显示控制单元,用于使显示器显示与指定地点相对应的图像;声音采集信号输入单元,用于输入收集用户声音的声音采集单元的声音采集信号; 具有围绕用户的麦克风,声信号处理单元,用于执行用于再现声场的第一声信号处理,其中感测到用户声音,如同声音在由收集声音的信号输入的信号中的位置回波, 信号输入单元,基于在该位置测量的第一传递函数,以指示在该位置内的封闭表面上发出的声音如何在该地方回波,然后传送到封闭表面侧;以及声发射控制单元, 导致基于处理的信号的声音从围绕用户的扬声器发射。
