Birdsong has previously been linked to lower stress levels and improved mood.
Traffic noise, by contrast, has been associated with stress and irritation, according to The Guardian.
More than 1,500 people took part in the new study, which was published in the journal People and Nature. They listened to nine different artificially created soundscapes featuring birdsong and traffic noise.
The participants were then asked how the sounds made them feel.

The researchers found that birdsong generally had a positive effect on participants' well-being.
We react differently
The study also found differences between participants. Younger people reported greater well-being than older people.
The researchers suggest that younger people generally have better hearing and may therefore experience the sounds in greater detail.
Participants also felt better when they believed they could hear many different species of birds.

The effect was greater among people who already knew more about birds.
According to the researchers, this suggests that experiencing a diverse range of birdlife may make the sounds of nature more beneficial.
Disruptions in everyday life
According to The Guardian, the study found that even relatively low levels of traffic noise could reduce the positive effects of birdsong.
Measurements of some participants' heart rates also indicated a stronger physical stress response when traffic noise was part of the soundscape.

The researchers therefore believe that traffic noise should be taken into account when planning green spaces.
They mention lower speed limits and denser vegetation around parks as possible solutions.
