University of Tübingen study identifies most pleasant birdsongs

A study conducted by researchers at the University of Tübingen has identified the acoustic characteristics that humans find most pleasant in birdsong. Published in ‘Frontiers in Bird Science’, the research involved 84 participants rating the vocalizations of 123 different bird species.

The Common Blackbird was ranked as having the most pleasant song, receiving an average score of 4.52 out of 5. Other high-ranking species included the willow warbler and the blackcap, while the barn owl was rated as the least pleasant.

Researchers found that humans generally prefer songs that are complex, varied, and higher-pitched, provided they are not excessively loud. High amplitude, or volume, was associated with lower pleasantness ratings. Notably, the study found that a person’s level of expertise or knowledge regarding birds did not influence their perception of the songs, suggesting that the appreciation of certain birdsongs may be a fundamental human trait.

Scientists noted that these findings could assist in designing restorative environments, such as parks or hospital waiting rooms, by utilizing ‘restorative’ bird species whose songs are known to reduce stress and promote psychological well-being.
