Slight-Mild Sensorineural Hearing Loss in Children: Audiometric, Clinical, and Risk Factor Profiles

OBJECTIVES:Slight or mild hearing loss has been posited as a factor affecting speech, language, learning, and academic outcomes, but the risk factors for slight-mild sensorineural hearing loss (SNHL) have not been ascertained. The two specific aims for this research were (1) to describe the audiometric and clinical characteristics of children identified with slight-mild bilateral SNHL and (2) to compare children with slight-mild SNHL with those with normal hearing (NH) with respect to potential risk factors for congenital or acquired for hearing loss. DESIGN:A cross-sectional cluster sample survey of 6581 children enrolled in years 1 and 5 of Australian elementary school was completed. Children were screened for slight-mild SNHL, defined as a low- and/or high-frequency pure-tone average of 16 to 40 dB HL in the better ear, with air-bone gaps
