Building upon the psychoacoustic techniques originally developed in Europe and further refined over the past 8 years in the U.S. by Dynamic Listening Systems (DLS), iLs programs combine auditory stimulation with balance, movement and visual motor activities.
The design of iLs programs is based around the listening component. Each product has a specific listening schedule, into which the balance and visual activities are included. These "integrating" activities comprise 15-20 minutes of each listening session, and are explained in a Playbook which accompanies each product.
