The EASe CD is an easy to use, simple and safe tool for occupational therapists, physical therapists, speech therapists, and parents, to teach a child challenged with sensory processing issues, sound sensitivity, hearing or developmental issues, to better manage noise. EASe CD #4 is designed to compliment EASe CD's #1, 2 and 3. The EASe CD #4 contains open ocean dolphin and whale songs, natural crickets and dynamically encoded music.One of the disadvantages that EASe has in regard to other auditory stimulation techniques such as AIT (auditory integration training) is the amount of variation that can be contained in one, one hour long compact disc as opposed to many hours of in-office therapy. To address that problem we have created additional EASe CDs to compliment EASe CD #1. We now have ten EASe CD's, totalling ten hours of therapy.
