Hearing Thresholds for a Geriatric Population Composed of Korean Males and Females

BACKGROUND AND OBJECTIVES: The purpose of the present study was to provide the hearing threshold levels in the elderly Korean population, and to compare Korean data with that in the International Organization for Standardization (ISO) 7029 (2000). SUBJECTS AND METHODS: Data were collected from a total of 526 ears from 112 males and 151 females aged 60-84 years. All participants were screened otologically by the procedure given in ISO 8253-1 (2010). RESULTS: Results showed that the pure-tone average was gradually elevated with increasing age. The amount of hearing loss was greater in males than in females, and the high frequency hearing thresholds were worse than the low frequency hearing thresholds in males and females. The hearing threshold levels were higher at low frequencies in males and at all frequencies in females than the norms of ISO 7029 (2000). CONCLUSIONS: Results from this study will be partly used for standardization of hearing thresholds as a function of age in Korea and for updating the ISO 7029.
