청각장애인의 난청 종류, 정도, 형태 등을 평가하기 위해 순
음을 사용하여 주파수별 청력역치를 측정한다. 그러나 순음청
력역치만으로 실제 의사소통 시 사용하는 다양한 청각적 능력
을 평가하기는 제한적이다(Killion & Niquette, 2000). 이를 보
완하기 위해 청능사(audiologist)는 어음청각검사를 시행하여
난청인의 어음 인지 능력과 의사소통 장애의 정도를 평가할 뿐
아니라 보장구 착용 혜택을 파악하고 청각재활을 계획하는 데
활용한다(Killion et al., 2004).

영어 초록

Purpose: Daily communication often requires the ability to understand speech in background noise. Given that speech-in-noise understanding
is not predictable from speech recognition in quiet and that sentences are more representative of daily communication, different
forms (fixed vs. adaptive) of sentence-in-noise tests have been developed and standardized. Relative to the fixed test, the adaptive sentence-
in-noise tests are known to be more useful to adjust the difficulty level of the test. Given this advantage, the present review focuses
on the features of the adaptive sentence-in-noise tests. Methods: Various types of adaptive sentence-in-noise tests have been developed
internationally and standardized for multi-language. This paper compares and summarizes three adaptive sentence-in-noise tests (Hearing
in Noise Test, Quick Speech-In-Noise test, and Matrix test) in terms of the three aspects: 1) sources of target sentences and background
noise, 2) test procedure and scoring formula, and 3) norms and interpretation of test results. Results: For all the types of adaptive tests,
the intensity level of the target sentence or the noise is adjusted based on the listener’s response. The sources of target sentences and
background noise differ among tests. Various multi-lingual versions of the Hearing in Noise Test and the Matrix test have been developed
and reported. All the three tests measure sentence recognition threshold where correct sentence recognition of 50% occurs. However,
the test procedure (i.e., presentation of stimuli/noise, the step size), the scoring formula, and the method to establish norms and interpret
the test results depend on the purpose of each test. Conclusion: Compared to other languages, a lack of Korean adaptive sentence-innoise
test tools poses challenges for clinical practice and research in Korea. Thus, development of the adaptive Korean sentence-in-noise
test which is reliable and efficient is required to quantify speech-recognition abilities of listeners with hearing loss. After developing the
adaptive test, the reliability and validity tests need to be continued to estimate the amount of everyday communication difficulty sensitively
and to provide better insights into the appropriate amplification and communication strategies.
