<p>　　We established age-dependent and side-dependent reference values for auditory processing test (APT) batteries. This study was conducted in 53 subjects aged 20-59 years with normal hearing. The results of the APT were used to establish reference values for each 10-year age group, using the 2SD method. Reference values for the tests performed on one ear at a time were established separately as the “superior” or “inferior” side, depending on the results for each test item.</p> <p>　　Statistical differences among age groups were noted in the following test items: dichotic listening test, speech recognition under multi-talker noise (signal to noise ratio of +15dB, +10dB, and +5dB) of the Hatta-Ota version of APT, dichotic listening monosyllable test, fast speech recognition test (2x speed, mid-word), and speech recognition under speech noise of the Obuchi version of APT. The dominant test performance side was almost equally distributed between the right and left sides, even though most of the participants were right-handed. Based on these results, we propose different reference values for the APT for different age groups. We further propose setting up separate reference values for tests conducted on one ear at a time by the superior and inferior sides for each test item.</p>
