Abstract

BACKGROUND AND OBJECTIVES: To develop and apply a diagnostic test tool for central auditory processing disorder (CAPD) and to obtain normative data of Korean subjects with normal hearing.
SUBJECTS AND METHOD
After obtaining the approvement of the Institution Review Board of Asan Medical Center for this clinical study, we conducted this study for 135 subjects with normal hearing. Frequency & duration pattern tests and dichotic test were administered to subjects with normal hearing were evaluated by pure tone audiometry. Patients were separated into the following age categories:up to and including 7-year-olds, 8- and 9-year-olds, 10- and 11-year-olds, 12- to 18-year-olds and adults over 18.
RESULTS
The frequency pattern test showed that the mean score was 14.4+/-7.1, 19.7+/-9.2, 23.8+/-8.6, 24.1+/-7.0 and 28.5+/-2.7, for each age category, respectively. The duration pattern test showed that the mean score was 13.8+/-6.2, 17.0+/-6.1, 21.6+/-5.4, 25.6+/-4.3 and 28.4+/-2.1, respectively. The dichotic test showed that the right mean scores were 26.5+/-3.2, 27.0+/-3.2, 27.8+/-3.2, 29.4+/-0.9, 27.9+/-1.5 and left the mean scores 26.4+/-3.7, 27.0+/-2.6, 28.6+/-1.4, 28.6+/-1.3, 27.9+/-1.6 for each age category, respectively.
CONCLUSION
We obtained the normative data of Korean subjects for the diagnosis of CAPD. Additional diagnostic tools and treatment methods must be developed continuously.
