Background noise acceptance while listening to speech, assessed via the acceptable noise level (ANL) measure, has been shown to be an accurate predictor of hearing-aid success. No specific listener characteristics have been identified as being related to a listener's ability to accept background noise. The purpose of this study was to determine whether or not locus of control and self-control are related to ANL.
Correlational design.
Participants were seventy young adults (21 male, 49 female; aged 19 to 39 years) with normal hearing. Participants completed psychological profiles that evaluated locus of control and self-control and their ANLs were measured.
Results revealed correlations between ANL and self-control. Listeners with higher levels of self-control accepted more background noise than listeners with lower levels of self-control.
This research suggests that exercises aimed at strengthening a listener's auditory self-control may lead to improved background noise acceptance. Improvement in background noise acceptance could lead to improved hearing-aid success. Future research should explore these possibilities.
通过可接受噪声级（ANL）评估，背景噪声下的言语聆听接受能力被证明是助听器效果的准确预测指标。目前还没有发现与聆听者接受背景噪声能力相关的特定个体特征。本研究旨在确定控制源和自我控制是否与 ANL 相关。
相关设计。
70 名年轻成年人（21 名男性，49 名女性；年龄 19 至 39 岁），听力正常。参与者完成了心理特征评估，包括控制源和自我控制，并测量了他们的 ANL。
结果显示 ANL 与自我控制之间存在相关性。自我控制水平较高的聆听者比自我控制水平较低的聆听者能接受更多的背景噪声。
这项研究表明，旨在增强聆听者听觉自我控制的练习可能会导致背景噪声接受能力的提高。背景噪声接受能力的提高可能会导致助听器效果的改善。未来的研究应该探索这些可能性。
