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?

The Wikimedia movement is searching for a sound logo that will identify content from all of our projects, like Wikipedia, when visual logos are not an option — for example, when virtual voice assistants answer queries.

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.
