背景：LISN&LINE听觉训练软件是专门为提高疑似中枢听觉处理障碍(SPD)儿童的双耳处理能力而开发的。SPD在这里被定义为一种情况，即个体在使用双耳提示选择性地注意来自一个方向的声音同时抑制来自另一个方向的声音的能力方面存在缺陷。目的：开发和评估LISN&LINE听觉训练软件，用于经空间噪声句子听力测验(LISN-S)诊断为SPD的儿童。LISS-S是一种自适应噪声中语音测试，旨在鉴别诊断疑似中枢性听觉加工障碍儿童的空间和基音处理缺陷。研究样本：9名儿童(年龄在6岁9个月到11岁4个月之间)，他们在LISS-S上的表现超出了正常范围。研究设计：在治疗结果的前期后研究中，参与者接受LISN训练，每天学习15分钟，持续12周。参与者充当他们自己的对照。参与者被评估了LIS-S，以及注意力和记忆力测试以及听力能力自评问卷。在没有进一步训练的3个月后，对所有任务的表现进行了重新评估。干预：LISN&LINE在用户的家庭计算机上的耳机下产生了一个三维听觉环境。孩子的任务是从背景噪音中出现的目标句子中辨认出一个单词。结果：在训练过程中，LISN和LEARN上的语音接收阈值平均提高了10分贝。根据假设，在LISN-S条件下，目标和分心刺激在空间上分离，并且专门评估双耳处理能力的情况下，训练后的表现有显著改善(p范围从
Background: The LiSN & Learn auditory training software was developed specifically to improve binaural processing skills in children with suspected central auditory processing disorder who were diagnosed as having a spatial processing disorder (SPD). SPD is defined here as a condition whereby individuals are deficient in their ability to use binaural cues to selectively attend to sounds arriving from one direction while simultaneously suppressing sounds arriving from another. As a result, children with SPD have difficulty understanding speech in noisy environments, such as in the classroom.Purpose: To develop and evaluate the LiSN & Learn auditory training software for children diagnosed with the Listening in Spatialized Noise-Sentences Test (LiSN-S) as having an SPD. The LiSN-S is an adaptive speech-in-noise test designed to differentially diagnose spatial and pitch-processing deficits in children with suspected central auditory processing disorder.Study Sample: Participants were nine children (aged between 6 yr, 9 mo, and 11 yr, 4 mo) who performed outside normal limits on the LiSN-S.Research Design: In a pre-post study of treatment outcomes, participants trained on the LiSN & Learn for 15 min per day for 12 weeks. Participants acted as their own control. Participants were assessed on the LiSN-S, as well as tests of attention and memory and a self-report questionnaire of listening ability. Performance on all tasks was reassessed after 3 mo where no further training occurred.Intervention: The LiSN & Learn produces a three-dimensional auditory environment under headphones on the user's home computer. The child's task was to identify a word from a target sentence presented in background noise. A weighted up-down adaptive procedure was used to adjust the signal level of the target based on the participant's response.Results: On average, speech reception thresholds on the LiSN & Learn improved by 10 dB over the course of training. As hypothesized, there were significant improvements in posttraining performance on the LiSN-S conditions where the target and distracter stimuli are spatially separated and which specifically evaluate binaural processing ability (p ranging from
