To determine if postlingually deaf adult cochlear implant (CI) users have better environmental sound awareness (ESA) compared with adult patients eligible for CIs who have not yet undergone implantation.
Cross-sectional cohort study.
Tertiary referral center.
A group of 39 postlingually deaf adult patients who are experienced CI users (ECI), and a group of 20 postlingually deaf adult patients who are cochlear implant candidates (CIC) awaiting implantation.
Cochlear implantation.
Environmental sound awareness as measured by accuracy (percent correct) using the computerized, Familiar Environmental Sounds Test-Identification (FEST-I).
There was no significant difference between ESA in our sample of ECI users versus CIC patients. The ECI users scored an average FEST-I accuracy of 59.9% (SD 14.3). In comparison, the CICs had an average FEST-I accuracy of 54.7% (SD 26.4). This difference was not statistically significant.
Our findings suggest that, despite the commonly held notion that improved ESA may be a benefit of cochlear implantation, our sample of ECI users did not demonstrate superior performance compared with CICs.
比较成年后天聋人工耳蜗（CI）使用者与尚未植入人工耳蜗但符合植入条件的成年患者的环境声音感知（ESA）能力，以确定前者是否更佳。
横断面队列研究。
三级转诊中心。
一组 39 名后天聋成年人工耳蜗使用者（ECI），以及一组 20 名后天聋成年人工耳蜗候选者（CIC），他们正在等待植入。
人工耳蜗植入。
使用计算机化的熟悉环境声音测试识别（FEST-I），通过准确性（正确百分比）来衡量 ESA。
在我们的 ECI 用户与 CIC 患者样本中，ESA 没有显著差异。ECI 用户的 FEST-I 平均准确率为 59.9%（SD 14.3）。相比之下，CIC 的平均准确率为 54.7%（SD 26.4）。这一差异没有统计学意义。
我们的发现表明，尽管普遍认为人工耳蜗植入可能带来更好的 ESA，但我们的 ECI 用户样本与 CIC 相比并未表现出更高的性能。
