It doesn’t take much to change our emotional state. According to recent research published in Journal of Environmental Psychologyjust one minute of natural sounds can significantly influence stress and concentration. But the most surprising fact does not concern the amount of nature listened to, but rather its origin: the human brain reacts better to familiar sounds than to those coming from distant and complex ecosystems.
The nature we know works better than the exotic one
The study compared different soundscapes, comparing recordings from European temperate forests with those from tropical forests. The initial hypothesis was that greater acoustic biodiversity – that is, more animal species recognizable in sounds – could generate a stronger positive effect.
The result has overturned expectations: it is not the variety that matters most, but the degree of recognisability. The sounds of birds inhabiting environments close to participants’ daily lives were perceived as more relaxing, clearer and even more “refreshing” than those of distant, unfamiliar forests.
The experiment and the brain’s response
A group of researchers led by Aletta Bonn involved 195 students, subjecting them to listening to short environmental recordings lasting one minute. There were two variables: the quantity of animal species present in the sounds and the geographical origin of the sound environment.
Before and after listening, participants rated their emotional state, perceived level of stress and ability to concentrate. The results were clear: even a very short exposure to sound nature improves mood, but the effect is stronger when the sounds are associated with familiar experiences.
Familiarity beats biodiversity
As mentioned, however, one of the most interesting aspects that emerged concerns perception. The sounds of European forests were judged more pleasant and “closer” than tropical ones. This generated a more positive emotional response and a greater feeling of psychological well-being.
The mere presence of many different species did not produce the same effect. In some cases it increased the feeling of wonder, but only when the sounds were already recognisable. The brain, therefore, does not only respond to complexity, but above all to the ability to interpret what it hears.
The role of perception in the nature of sound
Another key element concerns subjective perception. When participants believed they were listening to multiple animal species, they reported an improvement in their mood even though, in reality, the number of species was limited. This suggests that it is not just acoustic reality that influences well-being, but also how the brain interprets it. In contrast, sounds that were too complex or difficult to identify reduced the positive effect. Indistinct or barely recognizable noises do not activate the same relaxation mechanism.
The everyday soundscape as a mental resource
The final result of the study redesigns our relationship with nature. You don’t need to seek out remote environments or exotic ecosystems to gain psychological benefits. Even a simple park outside the house, with the song of a robin or a blackbird, can have a concrete impact on our mental balance. The brain seems to build a direct link between familiarity and security: what it knows relaxes it, what it recognizes stabilizes it. In this sense, everyday nature becomes an accessible resource, always available, capable of improving well-being immediately.
