摘　　要：听觉距离感知是人耳的基本功能之一,研究其机理对于人工智能等领域具有重要意义。实际环境中的听觉距离感知除了受声场要素的影响外,还受到噪声的干扰,以室内环境为研究对象,利用主观听觉实验研究背景噪声、声源信号的信噪比对听觉距离感知规律的影响。ADP （Auditory Distance Perception） is one of the fundamental functions of human ears and is very significant for the areas such as artificial intelligence. In the real environment, besides the essential factors of the sound field, noise also has influence on ADP. In this paper, the impact of background noise and SNR（Signal-to- Noise Ratio） on ADP is studied based on subjective hearing experiments.

关 键 词：听觉距离感知 背景噪声 信噪比
