What is Longitudinal study of children's hearing: Its relationship to noise and other factors about?
Six-month auditory threshold levels (ATL) have been obtained from children aged 6 to 18 years over a 4-year period. The means decrease with age especially at lower frequencies. Past otological problems are associated with poorer hearing. Stature and thresholds are not associated in boys, but taller girls tend to have worse hearing at younger ages and better at older ages. After the effects of stature are removed, rapid maturation is associated with lower thresholds in boys from 10 to 18 years and in girls at 8 and 9 years. Mean thresholds are significantly higher in those reporting higher noise exposure, especially from loud TV and power tools. High thresholds are associated with elevated systolic pressures in boys but with low pressures in girls. There are no associations with diastolic pressure or between noise exposure and blood pressure. Leq(24) levels have been obtained using General Radio and Metrosonics dosimeters. The mean Leq(24) for these children is between 77 and 84 dB with no significant age or sex effects; Leq(24) was correlated with ATL in girls but not boys. [Work supported by USAF and EPA.]
