Characterize performance for adults aged 20 to 79 years with normal hearing on tasks of AzBio, Bamford-Kowal-Bench speech-in-noise (BKB-SIN), quick speech-in-noise (QuickSIN), and acoustic Quick Spectral Modulation Detection (QSMD) in the sound field.
Cochlear implant (CI) program.
Eighty-one adults with normal hearing and cognitive function were recruited evenly across four age groups (20-49, 50-59, 60-69, and 70-79 yr).
Subjects completed AzBio sentence recognition testing in quiet and in five signal-to-noise ratios (SNRs: +10, +5, 0, -5, -10 dB), as well as the BKB-SIN, QuickSIN, and QSMD tasks.
AzBio, BKB-SIN, QuickSIN, and acoustic QSMD scores were analyzed to characterize typical sound field performance in an older adult population with normal hearing.
AzBio sentence recognition performance approached ceiling for sentences presented at ≥ 0 dB SNR with mean scores ranging from 3.5% at -10 dB SNR to 99% at +10 dB SNR. Mean QuickSIN SNR-50 was -0.02. Mean BKB-SIN SNR-50 was -1.31 dB. Mean acoustic QSMD score was 88%. Performance for all measures decreased with age.
Adults with age-normative hearing achieve ceiling-level performance for AzBio sentence recognition at SNRs used for clinical cochlear implant and/or hearing aid testing. Thus, these tasks are not inherently contraindicated for older listeners. Older adults with normal hearing, however, demonstrated greater deficits for speech in noise compared to younger listeners-an effect most pronounced at negative SNRs. Lastly, BKB-SIN data obtained in the sound field replicated previous normative data for only the youngest age group, suggesting that new norms should be considered for older populations.
描述年龄在 20 至 79 岁、听力正常的成年人在 AzBio、Bamford-Kowal-Bench 言语噪声比（BKB-SIN）、快速言语噪声比（QuickSIN）和声学快速频谱调制检测（QSMD）任务中的表现。
人工耳蜗（CI）项目。
81 名听力和认知功能正常的成年人按年龄分为四组（20-49 岁、50-59 岁、60-69 岁和 70-79 岁），每组各有 21 人。
受试者在安静环境和五个信噪比（SNR：+10、+5、0、-5、-10dB）下完成了 AzBio 句子识别测试，以及 BKB-SIN、QuickSIN 和 QSMD 任务。
分析 AzBio、BKB-SIN、QuickSIN 和声学 QSMD 评分，以描述听力正常的老年人群的典型声场表现。
在 SNR≥0dB 的情况下，AzBio 句子识别的表现接近上限，平均得分范围从-10dB SNR 时的 3.5%到+10dB SNR 时的 99%。平均 QuickSIN SNR-50 为-0.02dB。平均 BKB-SIN SNR-50 为-1.31dB。平均声学 QSMD 评分为 88%。所有指标的表现均随年龄的增长而下降。
听力正常的成年人在用于临床人工耳蜗和/或助听器测试的 SNR 下，可达到 AzBio 句子识别的上限水平。因此，这些任务对老年听众来说并不是固有禁忌的。然而，听力正常的老年成年人在噪声中的言语表现比年轻成年人表现出更大的缺陷，这种效应在负 SNR 时最为明显。最后，声场中的 BKB-SIN 数据仅复制了最年轻年龄组的先前正常数据，这表明应该为老年人群考虑新的正常数据。
