The purpose of this study was to determine (a) if acceptable noise levels (ANLs) are different in cochlear implant (CI) users than in listeners with normal hearing, (b) if ANLs are related to sentence reception thresholds in noise in CI users, and (c) if ANLs and subjective outcome measures are related in CI users.
ANLs and the Hearing in Noise Test (HINT; M. Nilsson, S. Soli, & J. Sullivan, 1994) were examined in 9 adult CI users and 15 adult listeners with normal hearing. In addition, the Abbreviated Profile of Hearing Aid Benefit (APHAB; R. M. Cox & G. C. Alexander, 1995) and a satisfaction questionnaire were administered to CI users only.
Results indicated that (a) ANLs were not significantly different for CI users and listeners with normal hearing, (b) ANLs were not correlated with HINT values for either group, (c) ANL was not significantly correlated with APHAB scores, and (d) ANL was significantly correlated with overall CI benefit on the satisfaction questionnaire.
CI users with large ANLs reported more benefit from implants than those with small ANLs. The results of this preliminary study of ANL in CI users suggest that ANL can be used as a tool for evaluating processing in noise in individual CI users.
本研究的目的是确定：(a) 人工耳蜗（CI）使用者的可接受噪声水平（ANL）是否与正常听力的聆听者不同；(b) CI使用者的ANL是否与噪声环境下的句子接受阈值相关；以及(c) CI使用者的ANL与主观结果测量指标是否相关。
对9名成年CI使用者和15名成年正常听力聆听者进行了ANL和噪声环境下听力测试（HINT；M. 尼尔森、S. 索利和J. 沙利文，1994）。此外，仅对CI使用者进行了助听器效益简表（APHAB；R. M. 考克斯和G. C. 亚历山大，1995）和满意度问卷调查。
结果表明：(a) CI使用者和正常听力聆听者的ANL无显著差异；(b) 两组的ANL与HINT值均无相关性；(c) ANL与APHAB得分无显著相关性；以及(d) ANL与满意度问卷中CI的总体效益显著相关。
ANL较高的CI使用者比ANL较低的使用者从植入物中获得的益处更多。这项关于CI使用者ANL的初步研究结果表明，ANL可作为评估个体CI使用者在噪声环境中处理能力的工具。
