| 摘 要： | 研究45,50,55,60 dB(A)等4种声压级下的鸟叫声、流水声和安静状态(背景噪声为38 dB(A))的恢复性效应.结果表明:声压级大小对鸟叫声和流水声的注意力和心理恢复效果均存在重要影响,45 dB(A)的鸟叫声和流水声对心理状态的恢复效果最好,50 dB(A)的鸟叫声和流水声对注意力表现的恢复效果最好;鸟叫声、流水声状态(45,50 dB(A))与安静状态对比,鸟叫声和流水声的注意力恢复效果和心理恢复效果显著优于安静状态.此外,在各种声压级下,鸟叫声和流水声的注意力恢复效果和心理恢复效果均无显著差异,在45,50 dB(A)下,鸟叫声的注意力恢复效果和心理恢复效果均略高于流水声.

| Abstract: | The recovery effects of bird sound, water sound and quiet state(38 dB(A)background noise)were studied under four sound pressure levels(45,50,55 and 60 dB(A)). The results show that the sound pressure level has an important effect on the attention and psychological recovery of both bird sound and water sound. The bird sound and water sound at 45 dB(A)has the best recovery effect on the psychological state, and the bird sound and water sound at 50 dB(A)has the best recovery effect on the attention performance. Compared with the quiet state, the attention recovery and psychological recovery effects of bird sound and water sound are significantly better than that in the quiet state. In addition, there are no significant differences in the attention recovery and psychological recovery effects between bird sound and water sound at various sound pressure levels. At 45,50 dB(A), the attention recovery and psychological recovery effects of bird sound are slightly higher than that of water sound. |
