These wooden megaphones were installed by architecture students in Estonia to allow forest trekkers to better listen to the sounds of nature – the rustling of the leaves, the flowing creeks, the chirping birds and rainfall. They're electricity-free, sturdy and gigantic. In fact, they're so large that they can function as tiny stages for musicians or accommodate hikers who need temporary shelter.
Located at Pähni Nature Centre in southern Estonia, the structures are placed at a predetermined distance and at specific angle to create a sound feed in the center of the installation. They're free for all visitors to enjoy and will remain in the forest until the wood is reclaimed by nature.
