"Sound helps shape our perception and how we learn about the world around us. Some sounds are quite simple to identify, like the sound of a rocket launch or the sound of waves crashing against the shore. But how about the sound of all human knowledge?
Through an open contest, organised by the Wikimedia Foundation, we are inviting the world to create The Sound of All Human Knowledge. This sound will help communicate what the Wikimedia movement stands for — trustworthy, reliable, open, and accessible knowledge for all."
