title: Middle ear resonance and acoustic immittance measures in children.
abstract: This study established a normal middle ear resonance estimated from sweep frequency tympanometry (250-2000 Hz) and established normal equivalent ear canal volume, static acoustic admittance, and tympanometric peak pressure at 226 Hz in children with normal hearing (N = 90) and in children with severe to profound sensorineural impairments (N = 68). Children's ages ranged from 6 to 15 years. No statistically significant differences between the groups or across ages were found. Means, standard deviations, and 90% ranges (5-95%) for these four tympanometric measures are presented and compared to other studies.
