Clairaudience is defined as "the act of hearing, or the ability to hear sounds not normally audible; claimed as a special faculty in connection with Spiritual Mediumship." If you possess Clairaudient powers, the Crystal will help to bring them to your consciousness. The same experiments as suggested for Crystal gazing may be carried out, except, of course, instead of visions or pictures in the Crystal, the Psychic Phenomena will become apparent in sound, as though the words were actually spoken.
