Abstract

The purpose of the present study was to determine typical acceptable noise levels (ANLs) in children diagnosed with auditory processing disorder (APD) and compare those to ANLs in children without APD. Sixteen participants, eight children with APD and eight children without APD, were administered a complete audiological evaluation and a series of APD tests [Filtered Words, Competing Sentences, and Auditory Figure Ground (0) subtests of the SCAN– 3C; Staggered Spondaic Word test; and Pitch Pattern test] to determine normal or abnormal auditory processing ability. Conventional ANLs were measured on each participant to determine acceptance of background noise. The results revealed no significant difference for ANLs in participants with and without APD; however, a trend for lower ANLs in those without APD seemed to be presented. Furthermore, the results showed no significant correlation between ANL and any administered APD test. Possible clinical implications/applications were discussed.
