Just received an email about a new sleep product from iLs that helps with auditory sensitivity. It is priced at $295 and available for purchase by parents. It is described as follows:
The iLs Pillow delivers processed music through a vibration which is carried by the body (our bones are great conductors). The music travels internally to the bony area surrounding the inner ear, and is audible only by the user. It is used to de-senstitize those with auditory sensitivity, reduce anxiety and improve sleep.
