Evaluating psychometric properties of the Cantonese integrated Digit-in-Noise Test: perhaps the 2-digit sequence can also be used for hearing screening.

Objective: This study developed and validated the Cantonese integrated Digit-in-Noise Test (iDIN) for speech-in-noise measurement and hearing screening.

Design: The development of the Cantonese iDIN followed the International Collegium of Rehabilitative Audiology guidelines. Its psychometric properties, including normative data, psychometric function, test-retest reliability, and criterion validity, were established.
