초록
The purpose of this study was to examine characteristics of geriatric hearing loss based on word recognition scores (WRSs) in terms of response patterns. Three hundred hearing impaired participants whose age range was 55 to 92 years, grouped 55~64, 65~74, and 75+, performed WRSs and puretone audiometry with the agreements. The results showed as follows. First, the results showed no gender difference, but showed difference in age group and the degree of hearing loss with PT average with 500, 1,000, and 2,000 Hz. As the age and the degree of hearing loss increased, WRSs decreased. Second, 2,000 Hz puretone thresholds were most important to WRSs with statistical significant correlations of 42 words out of 50, followed by 1,000, 4,000, 500, 250, 8,000 Hz in the order. Third, initial consonants and vowels which showed 5 or more frequencies /ㄱ, ㄷ, ㅅ, ㅇ, ㅈ/ and /ㅏ, ㅓ, ㅗ, ㅜ, l/ revealed statistical significance whereas final consonants did not. Fourth, the average hearing thresholds figures of the participants who showed lower than 70% WRSs and higher than 90% WRSs were similar. Conclusively, this results should be considered in rehabilitation process and hearing aid fitting for the geriatric population.
Abstract
The purpose of this study was to examine characteristics of geriatric hearing loss based on word recognition scores (WRSs) in terms of response patterns. Three hundred hearing impaired participants whose age range was 55 to 92 years, grouped 55~64, 65~74, and 75+, performed WRSs and puretone audiometry with the agreements. The results showed as follows. First, the results showed no gender difference, but showed difference in age group and the degree of hearing loss with PT average with 500, 1,000, and 2,000 Hz. As the age and the degree of hearing loss increased, WRSs decreased. Second, 2,000 Hz puretone thresholds were most important to WRSs with statistical significant correlations of 42 words out of 50, followed by 1,000, 4,000, 500, 250, 8,000 Hz in the order. Third, initial consonants and vowels which showed 5 or more frequencies /ㄱ, ㄷ, ㅅ, ㅇ, ㅈ/ and /ㅏ, ㅓ, ㅗ, ㅜ, l/ revealed statistical significance whereas final consonants did not. Fourth, the average hearing thresholds figures of the participants who showed lower than 70% WRSs and higher than 90% WRSs were similar.
