Tinnitec Clairaudience, which means "Clear Hearing." This energy center is at the 5th chakra, located at your throat. (There are also smaller chakras at your ears.) Clairaudience is about communication, which is the 5th chakra's job. Clairaudience doesn't mean you literally hear someone speak out loud to you when you're alone (although that can happen in some situations). Rather, when you ask a question to your guides (or the Divine or the angels), you receive the answer in the form of words inside your head, as opposed to a vision, or a visual picture. Neale Donald Walsh, the author of the "Conversations with God" series, is a good example of clairaudience.
