The present study examined the effect of progressive filter testing in children with normal auditory processing skills and children with (central) auditory processing disorders [(C)APD]. The primary purpose of this study was to determine if a new screening procedure designed by the investigator called Progressive Filtering would differentiate between a control group (i.e. children with normal auditory processing skills) and an experimental group [children with (C)APD]. Twenty subjects (age 6 to 14 years) participated in the study. All subjects received an audiological examination, an auditory processing test battery, and the Progressive Filtering screening tool. Results indicated that the investigator-designed Progressive Filtering screening tool did differentiate between the control and experimental groups for certain frequencies.
