A system and method upper auditory frequency range hearing. A speech signal is filtered, and then modulated to an upper auditory frequency range. The modulated signal is then provided to a transducer, which causes a vibration in the ear canal, the head or the neck of a user, which is received in an inner ear of the user. That vibration is translated as a signal to the brain, which interprets that signal as intelligible speech.
