| 中文摘要: |
| 为了探讨人体侧卧状态下垂直轴向距离感知的规律，在消声室中进行了听音实验，并将其和仰卧状态下的实验数据进行对比分析。结果表明，侧卧状态下垂直轴向距离感知与信号频率及信号种类相关。在人体下方的距离感知中，纯音信号的距离感知趋势和窄带信号的距离感知趋势大体相同，在人体上方的距离感知中，窄带信号的距离感知趋势较纯音信号的距离感知趋势有一定的提升。 |
| 英文摘要: |
| In order to explore the law of vertical axial distance perception in the lateral lying state of human body, the subjective listening experiment is carried out in the anechoic chamber, and the experimental data are compared with the experimental data in the supine state. The experimental results show that the vertical axial distance perception in the lateral lying state is correlated with the signal frequency and the signal type. There is no significant difference between the pure and narrowband signals in the distance perception when the sound source is below the body. However, the distance perception trend of narrowband signal is improved to a certain extent compared with the pure tone signal when the sound source is above the body. |
