Experiment let the primates choose what they wanted to hear, with rumbling vehicles thought to mimic elements of their own communications
They may be naturally suited to swinging in rainforests, but monkeys in a Finnish zoo have demonstrated a “significant” preference for traffic sounds instead of the noises of the jungle, researchers have found.
As part of an experiment to see how technology could improve the wellbeing of captive animals, researchers installed a tunnel fitted with sensors in the enclosure of the monkeys at Helsinki’s Korkeasaari zoo, giving the primates the chance to choose to listen to the sounds of rain, traffic, zen sounds or dance music.
