It sounds to me like it's basically a white noise machine. For those who don't know there is a sound therapy called Auditory Integration Training (Berard AIT) - along with a book you can buy on Amazon called "Hearing Equals Behaviour: Updated and Expanded" that can help reduce or eliminate tinnitus; it more or less from my understanding and experience is allowing the brain to un-focus from the sound, from that sensory, allowing the brain and sensory input to equalize - as body is a system designed to constantly find homeostasis.
