One hundred eighty-five cases with functional hearing loss (39 males, 146 females) were investigated. The final audiogram obtained and the subjective awareness of hearing loss were examined. Follow-up of all the cases was intended until their audiogram became normal, or if this was not achieved in the near-term, for at least a year. According to the age at diagnosis, the cases were classified into 3 age groups; there were 130 cases in the under 11 years old group, 40 cases in the 12 to 17 years old age group, and 15 cases in the 18 years old or over age group. A normal audiogram at the final examination was obtained in 81.5% of the cases in the under 11 years old age group, 60% of the cases in the 12 and 17 years old age group and 47% in the 18 years old or more age group. Eighty-six percent of the cases in the under 11 years old age group were no longer conscious of their own hearing loss at the time of the final examination. On the other hand, a lower percentage, that is, 60% of the cases between 12 and 17 years old and 47% of the cases 18 years old or over were not aware of their hearing loss at the time of the final examination. About 20% of all the cases under 17 years old showed a discrepancy between the abnormalities in the final audiogram and the subjective awareness of hearing loss. Awareness of hearing loss is as important as audiometry test abnormality in the assessment of the seriousness of the functional hearing loss in the younger age group. The audiogram abnormality was well correlated with subjective hearing disturbance in the adults. Pure-tone audiometry is a good test to estimate the severity of functional hearing loss in adults.
