目前的研究调查了受试者感知自然发生的听觉事件(人类行走)的来源特征(人类步行者的性别)的能力。测量了一些声学特性，并进行了统计分析，以识别那些区分男性和女性行走脚步的特性。通过对频谱能量分布统计特性的主成分分析，确定了两类在确定受试者对步行者性别感知方面的重要信息：(1)频谱峰值，它综合了频谱中心的频率趋势和频谱峰值形状的信息；(2)高频频谱分量的贡献。随后的实验对这些光谱特性进行了处理，以验证它们在步行者性别感知分类中的作用。此外，通过让男性和女性步行者都穿男性的鞋子来评估鞋子对行走序列中性别判断的影响。
The current study investigated the ability of subjects to perceive source characteristics (the gender of a human walker) of a naturally occurring auditory event (human walking). A number of acoustic properties were measured and subjected to statistical analyses in order to identify those properties that differentiate male and female walking footsteps. A principal component analysis on the statistical properties of the spectral energy distributions then identified two classes of information that were important in determining subject perception of the gender of a walker: (1) the spectral peak which integrates the information about the spectral central tendency of frequency and shape of the spectral peak; and (2) the contribution of high-frequency spectral components. A follow-up experiment then manipulated these spectral properties to verify their contributions in the perceptual classification of walker gender. Additionally, the effect of shoe on the gender judgement in walking sequences was assessed by having both male and female walkers wear male's shoes.
