The Korean version of the DIN (K-DIN) test was previously validated for both normal-hearing and hearing-impaired listeners. This study aimed to explore the factors influencing the outcomes of the K-DIN test further by analyzing the threshold (representing detection ability) and slope (representing test difficulty) parameters for the psychometric curve fit.Subjects and Methods: In total, 35 young adults with normal hearing participated in the K-DIN test under the following four experimental conditions: 1) background noise (digit-shaped vs. pink noise); 2) gender of the speaker (male vs. female); 3) ear side (right vs. left); and 4) digit presentation levels (55, 65, 75, and 85 dB). The digits were presented using the method of constant stimuli procedure. Participant responses to the stimulus trials were used to fit a psychometric function, and the threshold and slope parameters were estimated according to pre-determined criteria. The accuracy of fit performance was determined using the root-mean-square error calculation.Results: The listener\u2019s digit detection ability (threshold) was slightly better with pink noise than with digit-shaped noise, with similar test difficulties (slopes) across the digits. Gender and the tested ear side influenced neither the detection ability nor the task difficulty. Additionally, lower presentation levels (55 and 65 dB) elicited better thresholds than the higher presentation levels (75 and 85 dB); however, the test difficulty varied slightly across the presentation levels.Conclusions: The K-DIN test can be influenced by stimulus factors. Continued research is warranted to understand the accuracy and reliability of the test better, especially for its use as a promising clinical measure.<\/jats:p>","DOI":"10.7874\/jao.2022.00472","type":"journal-article","created":{"date-parts":[[2023,3,22]],"date-time":"2023-03-22T02:07:23Z","timestamp":1679450843000},"page":"88-96","update-policy":"https:\/\/doi.org\/10.7874\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Factors Influencing the Korean Version of the Digit-in-Noise Test"],"prefix":"10.7874","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3812-2938","authenticated-orcid":true,"given":"Subin","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5657-7536","authenticated-orcid":true,"given":"Chanbeom","family":"Kwak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1623-9676","authenticated-orcid":true,"given":"Woojae","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8443-8581","authenticated-orcid":true,"given":"Jae-Hyun","family":"Seo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1083-7774","authenticated-orcid":true,"given":"Yonghee","family":"Oh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4621","reference":[{"key":"ref1","first-page":"1545","volume-title":"Global, regional, and national incidence, prevalence, and years lived with disability for 310 diseases and injuries, 1990\u20132015: a systematic analysis for the Global Burden of Disease Study 2015","year":"2016"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(11)61143-4"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2015.04.011"},{"key":"ref4","first-page":"155","volume-title":"","author":"V\u00f6lter","year":"2020"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.21848\/asr.200066"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1121\/1.2642072"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1121\/1.408469"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1121\/1.4789933"},{"key":"ref9","first-page":"17","volume-title":"International Collegium of Rehabilitative Audiology (ICRA) recommendations for the construction of multilingual speech tests.
