소음환경하에서의 어음명료도와 인지기능과의 상관관계에 대한 분석 = Analysis of Correlation between Cognitive Function and Speech Recognition in Noise

다국어 초록 (Multilingual Abstract)

Background and ObjectivesZZSpeech in the noise test has been known to reflect the distortion component of hearing impairment originated not only from the cochlea but also from the central auditory system. For communication with language, a proper cognitive function of the cerebral cortex is essential. In the present study, we aimed to evaluate the correlation between the cognitive function and the speech recognition ability against background noise.
Subjects and MethodZZThirty one listeners with sensorineural hearing loss in both ear participated in this study. We performed pure a tone audiometry, a speech recognition test with and without multitalker babble noise, a computerized cognitive function test and the Mini-Mental Status Examination-Korea.
ResultsZZSpeech recognition score in noise showed significant correlations with the results of both computerized cognitive function test and Mini-Mental Status Examination-Korea, whereas,the pure tone average and speech recognition score in the quiet background did not.
ConclusionZZThese results support that speech recognition ability in background noise reflects the cognitive function. Korean J Otorhinolaryngol-Head Neck Surg 2010;53:215-20
