Abstract

Twenty-eight children with steep high tone sensorineural hearing loss were analyzed. Those clinical findings were described as follows;<br>1) The number of patients according to the first frequency of their steep sloping was one in 0.5kHz, 7 in 1kHz, 15 in 2kHz, 3 in 4kHz and 2 in 8kHz.<br>2) Most of them were diagnosed at 7 years old after regular screening hearing test at their elementary school. Most of their parents had no doubt of their hearing loss.<br>3) Speech discrimination score (SDS) anylized in 2kHz steep frequency were distributed from 50% to 95%.<br>4) Articulation errors were appeared mostly in confusion of fricatives and unvoiced affricates.<br>5) 8 cases had the possibility of familial deafness, and the other 9 cases had asphyxia episode at their birth. These factors should be cared as a high risk of steep high tone hearing loss.
