This study examines auditory processing abilities of children with severe-to-profound unilateral sensorineural hearing loss. Children typically experience a right ear advantage until auditory maturation occurs during the early stages of adolescence. The objective of this study was to determine if laterality of the hearing loss impacts how auditory stimuli are processed. There were six subjects, 4 males and 2 females, ranging in age from 6 to 13 years. Two subjects had a left ear loss, while 4 subjects had a right ear loss. Each subject had a severe to profound unilateral sensorineural hearing loss, with normal hearing sensitivity and an absence of middle ear pathology in the opposite ear. The peripheral audiologic characteristics of the subjects were determined in the ear with normal hearing sensitivity by standard pure tone audiometry, tympanometry, physical examination, speech recognition thresholds, and distortion product otoacoustic emission testing. Subjects were administered a battery of auditory processing assessments, including Filtered Words, Auditory Figure Ground, Random Gap Detection Test, Pitch Patterns Sequence Test, and Time Compressed Sentence Test. Results are reported in the form of six case studies and performance on the auditory processing battery. Given the limited number of subjects, comparison data is not available. This is an ongoing study, with the intention of acquiring 50 subjects, with an equal distribution of male and female and right verses left ear hearing loss.
