I also get the sensation of "feeling" the sound in the brain by running the output audio signal from the tape, PC, or CD through a device such as the Flanagan Neurophone or the cheaper knockoff, the Echofone. You attach a pair of transducers on the temples. I combine it with the regular audio headphones. The electrodes are said to have a higher frequency response (400 Hz to 100,000 Hz) so it's better for Tomatis effects. Perhaps spoken suggestions may be enhanced by this technique.
