Abstract
Audiometric pattern in 76 cases of Congenital Sensorineural Hearing Loss (S.N.H.L.) with Delayed Development of Speech and Language (D.D. S.L.) were analysed in children from the ‘Deaf & Mute’ School in Benghazi. Air conduction threshold was recordable bilaterally in 89.3% of the cases and unilaterally in 15.7% of cases. Bone conduction threshold was observed in 3.9% of cases in the right ear and 5.2% of cases in the left ear. Hereditary pattern of audiogram was seen in 96.4% of cases, prenatal pattern in 1.8% of cases and perinatal pattern of audiogram in 1.8% of cases. The average threshold in the speech frequencies of 0.25 KHz, 0.5 KHz, 1 KHz and 2 KHz were 79.4 dl,, 89.0db, 97.9db and 97.3db respectively.
