Elizabeth Rintel and Derek Rintel conducted a study in Brisbane in 1995 using the Joudry Sound Therapy system on children in a remedial learning program. An experimental and a control group were used, each consisting of seven children. The experimental group (E group) received the Joudry Sound Therapy listening program and the control group (C group) listened to the same music without the Sound Therapy recording method. Due to time limitations the children received only 32 hours of treatment, which is less than the recommended minimum of 100 hours. This study can therefore be said to only partially demonstrate the effectiveness of the program.
Five normed tests were administered to the children. These were:
1) Test of Auditory discrimination (TAD); Goldman-Fristoe-Woodcock. (AGS 1970) revised 1976 using a standard audio cassette.
2) Neale Analysis of Reading Revised (Neale 1987)
3) Neale Analysis of Reading Revised (Neale Comprehension.)
4) Westwoood Spelling (1979)
5) Schonell Spelling Test
Parent and teacher observations were recorded on: Distractability, Overactive behavior, Reading improvement, Left/right confusion and Misinterpretation of questions.
The general trend on most of the indices of standard tests and parent-teacher observations was that the experimental group advanced faster than the control group.
