This study aimed to preliminarily investigate the associations between performance on the integrated Digit-in-Noise Test (iDIN) and performance on measures of general cognition and working memory (WM). The study recruited 81 older adult hearing aid users between 60 and 95 years of age with bilateral moderate to severe hearing loss. The Chinese version of the Montreal Cognitive Assessment Basic (MoCA-BC) was used to screen older adults for mild cognitive impairment. Speech reception thresholds (SRTs) were measured using 2- to 5-digit sequences of the Mandarin iDIN. The differences in SRT between five-digit and two-digit sequences (SRT5−2), and between five-digit and three-digit sequences (SRT5−3), were used as indicators of memory performance. The results were compared to those from the Digit Span Test and Corsi Blocks Tapping Test, which evaluate WM and attention capacity. SRT5−2 and SRT5−3 demonstrated significant correlations with the three cognitive function tests ( rs ranging from −.705 to −.528). Furthermore, SRT5−2 and SRT5−3 were significantly higher in participants who failed the MoCA-BC screening compared to those who passed. The findings show associations between performance on the iDIN and performance on memory tests. However, further validation and exploration are needed to fully establish its effectiveness and efficacy.

综合数字噪声测试中老年人助听器用户记忆性能的探索


本研究旨在初步调查综合数字噪声测试 (iDIN) 表现与一般认知和工作记忆 (WM) 测量表现之间的关联。该研究招募了 81 名年龄在 60 至 95 岁之间、双侧中度至重度听力损失的老年助听器使用者。中文版蒙特利尔认知评估基础版（MoCA-BC）用于筛查老年人是否存在轻度认知障碍。使用普通话 iDIN 的 2 至 5 位数字序列测量语音接收阈值 (SRT)。五位数字序列和两位数字序列之间的 SRT 差异（SRT 5−2 ），以及五位数和三位数序列之间（SRT 5−3 ），被用作内存性能的指标。结果与评估 WM 和注意力能力的数字跨度测试和 Corsi 块敲击测试的结果进行了比较。选择性RT 5−2和SRT 5−3与三项认知功能测试显着相关（rs 范围为 -.705 至 -.528）。此外，SRT 5−2和SRT 5−3与通过 MoCA-BC 筛查的参与者相比，未通过 MoCA-BC 筛查的参与者的这一比例显着更高。研究结果表明 iDIN 表现与内存测试表现之间存在关联。然而，还需要进一步的验证和探索来充分确定其有效性和功效。
