Abstract

It is difficult to detect the adult hearing loss after the language acquisition because of its slow progression, which can be evaluated voluntarily and actively when the appropriate tools are provided. Smartphones are one of useful tools, and they can utilize surveys and/or applications for hearing screening. This study aims to verify the possibility as a tool discovering delayed acquired hearing losses by comparing the pure tone screening application (app_PTS) which was recently developed by our research team and hearing handciap inventory (HHI). The subjects were 22 people whose age ranges from 10s to 80s. For pure tone averages (PTAs), hearing threshold level was selected the best one in same frequency, in both ears. Sensitivity and specificity of HHI were confirmed based on self awareness of hearing loss and PTAs at 1, 2, 4 kHz. Comparisons of two tests were measured by analyzing simple regression of correlation between PTAs of App_PTS and HHI scores. Sensitivity and specificity were 1.000 in both criteria. There was a statistically significant relationship between the PTAs_4 kHz and HHI (R-square = .951, p = .000). Hearing screening by questionnaire showed high correlation with smart phones based on application. Therefore, it can be useful as a hearing screening tool for individual life cycle using an user-friendly tool.

언어 습득 이후 성인 난청은 진행 속도가 느려서 발견이 어렵다. 이들은 적절한 도구를 제공하면 자발적이고 적극적인 평가가 가능하다. 스마트 폰도 도구들 중 하나이며, 설문이나 애플리케이션을 이용하여 효과적인 평가가 가능하다. 이 연구에서는 순음청각선별(pure tone screening, PTS)을 위한 스마트 폰 앱을 개발 후 이의 효과성을 검증하기 위해, 난청자각 설문조사방법(hearing handciap inventory, HHI)을 동시에 진행한 후 결과를 비교하여 진행 속도가 느린 지연성 후천성 난청 발견을 위한 도구로서 가능성을 확인하고자 한다. 대상은 10대부터 80대 사이 남녀 22명으로 하였다. 가청역치 평균(PTAs)은 두 귀 같은 주파수 가청역치 중 좋은 것을 선택(최량청력, best hearing)하였다. HHI의 민감도와 특이도는 난청 자각 여부나 PTAs_4 kHz를 기준으로 하였다. 두 검사 간 비교는 App_PTS의 PTAs와 HHI 점수 사이의 상관관계를 단순회귀 분석하였다. 민감도와 특이도는 두 기준 모두에서 1.000으로 관찰되었다. 최량청력 PTAs_4 kHz와 HHI 사이에는 통계적으로 유의한 관계를 보였다(R-square= 0.951, p= .000). 설문을 이용한 청각선별은 정량적 계측을 통해 구현한 스마트 폰 애플리케이션 기반 청각선별과 높은 상관관계를 보였다. 따라서 app_PTS는 개인 친화적 도구로 생애 주기별 청각선별에 유용하게 사용할 수 있을 것이다.
