Abstract

Humans can recognize approximate room size only by binaural audition. However, sound reverberation is not negligible in most environments. The reverberation causes temporal fluctuation in the short-term Interaural Phase Differences (IPDs) of sound pressure. In this study, a novel method for estimating room volume is proposed based on the short-term IPDs of sound pressure by using a binaural humanoid robot. The humanoid robot turns its head toward a sound source, recognizes the sound source, then estimates the ego-centric distance by its stereovision. By interpolating the relations between room volume, average standard deviation and egocentric distance experimentally obtained for various rooms in a prepared database, the room volume was estimated by binaural audition from the average standard deviation of short-term IPDs at the estimated distance.
基于双耳信号统计特性的仿人机器人房间体积估计
人类只能通过双耳听来识别房间的大致大小。然而,在大多数环境中,声音混响是不可忽略的。混响引起短期耳间声压相位差(IPDs)的时间波动。本文提出了一种基于声压短期ipd的双耳仿人机器人估算房间容积的新方法。人形机器人将其头部转向声源,识别声源,然后通过其立体视觉估计以自我为中心的距离。通过插值实验得到的各个房间的房间体积、平均标准差和自我中心距离之间的关系,用双耳听法从短期ipd在估计距离上的平均标准差估计房间体积。
