Study on the Correlation between Hearing Quality and Learning Ability (2001)

The researcher verified Dr. Berard’s hypothesis that hearing quality is so important for classroom activity that learning success and failure depend on its level. Three student groups were studied and the overall conclusion is: if a student’s grades are consistently low, you can guess that her/his hearing quality is poor. If an audio test shows that a child has a poor hearing quality, most probably she/he is not among the top students.
