The book is called "Hearing Equals Behaviour: Updated and Expanded" - can be found on Amazon - and the sound therapy is called Berard AIT or Auditory Integration Training; unfortunately there are people who claim to offer it, or have "at home" sessions they'll sell you where you rent equipment - however it's not the same high-end equipment that should be used, so "buyer beware." There are other sound therapies on the market that are reaching mainstream via well-written books, however the actual products they released don't seem to actually follow the AIT protocol and logically they shouldn't have anywhere near the same level of efficacy due to a few factors. I do know of a gentle old man in Montreal, Quebec, who was trained directly by Dr. Berard.
