An apparatus for training learning disabled subjects, such as autistic children, induces sound waves into a body of a user through two paths, one heard by the ears through air and the other through a liquid or solid in contact with tissues, such as skin and skeleton on the back of a user, below the collar and centered across the vertical axis of the spine. Two transducers produce waves in the audible sound spectrum, repeat persistently, and provide a tone about a location on which the subject may focus attention. A controller and actuator adhered to the skin by an adhesive gel pad against the back of a wearer. The sound, repeating (after a selected delay), decaying, and seeming to originate above and behind the head of a wearer is a waveform becomes a focus; effective to orient a subject, who lacks natural, self-orientation.
