We don’t know about you, but our idea of a hike in the woods doesn’t involve much in the way of noise, apart from the crunch of leaves underfoot and the occasional ‘cooee’.
That’s apparently a bit tame for the group of Estonian uni students who just built three whopping big megaphones in a forest near the Latvian border. Their aim is to help people appreciate the sound of nature by amplifying it.
Each wooden cone is positioned to create a surround-sound experience, and stretches about three metres in diameter – large enough to sleep in or be used as a performance stage. Their acoustics are actually so good that they’re capable of transforming a sparrow’s tweet into the piercing screech of an owl.
They can carry a human voice pretty well, too, which means they can be used as loudhailers if any members of your group get lost.
