摘　　要：人耳听觉是目前研究的热点之一,但是对于房间中声源定位的精度和感知机理,并没有很完善的研究。为此,通过主观实验,探究人耳在普通房间中的空间定向效果。采用布放在不同位置的7个音箱作为声源,比较不同性别被试对于男声、女声、白噪声这三种信号的判决正确率,并初步分析被试是否转头这个因素对判决正确率的影响。实验结果表明,在普通房间中,各种复杂的混响等因素会对声源的听觉定位精度造成一定的影响。Human hearing is one of current research hotspots, but accuracy and perception mechanism of source localization in rooms has not been well studied. Localization effect of human ear in an ordinary room is explored by subjective experiments in this paper.Seven loudspeakers located differently are used and judgement accuracies are compared with subjects of different genders. Three types of sound sources as male voices, female voices and white noises are utilized. Influence of head rotation is also analyzed. Experimental results show that in rooms, complicated factors including reverberation do affect accuracy of the sound localization.
