Abstract:

Aims: The aim of this study was to investigate the influence of birdsongs on the perception of natural soundscapes and the potential for soundscape restorativeness, and to provide reference for the public to achieve higher levels of restoration from nature.

Methods: In July and August 2021, we conducted a research in Beijing Xishan National Forest Park, where extra songs of ten bird species were played through speakers to enhance the diversity of birdsong in the environment. Educational signages were also installed to provide information about local bird species and their songs. A survey was conducted with 744 visitors to measure their perception of soundscape restorativeness and the level of birdsong diversity.

Results: Visitors in the environment with a greater diversity of birdsongs achieved higher level of soundscape restorativeness. Visitors who received educational information about birdsongs reported a higher level of perceived birdsong diversity. However, there was no correlation between visitors’ perceived birdsong diversity and the actual diversity of birdsongs in the environment.

Conclusion: The results indicate a positive correlation between the diversity of birdsong in the environment and the perceived soundscape restorativeness. Increased birdsong diversity can enhance visitors’ experiences and benefits in natural environments. The presence of educational signage can promote visitors’ attention to the soundscape and increase their perception of the birdsong diversity.
