Interesting development. I listened to a headphone a few years ago that had haptic sensors (transducers) for low bass. It did work. I can't help but think that this application will not be strictly for the deaf. Something like sonic VR for enhanced home enjoyment. Think wearable subwoofers at least, and probably something much more inclusive. At least until we have Holodecks like Star Trek TNG. "Feel the music" will never be quite the same. Awesome use of software. So many here have mentioned being adverse to headphones because they want the skin to be part of the experience. Well, here you are.
