背景：听觉稳态反应（ASSR）是一种听觉诱发电位（AEP），可用于客观评估听力敏感度正常以及不同程度和配置的感音神经性听力损失（SNHL）个体的听力敏感度。因此，许多听力学家希望更多地了解用于成功获得这种反应的刺激和记录参数，以及有关这种反应如何准确地预测不同临床人群的行为阈值的信息。目的：科学目标是为听力学博士 (Au.D.) 学生和具有有限（1-5 年）AEP 临床经验的听力学家创建有关 ASSR 的教程。本教程是必要的，因为与其他 AEP 相比，ASSR 在用于描述此响应的术语类型、用于记录此响应的刺激类型、这些刺激的传递方式、客观分析响应的方法以及用于校准刺激的技术方面是独一无二的。第二个目标是让听力学家了解 ASSR 能够估计各种成人和儿童临床人群的纯音阈值的准确性。设计：本教程分为多个部分，包括 ASSR 的历史、与此响应相关的独特术语、用于引发响应的刺激类型、两种常见的刺激方法、客观分析响应的方法、记录 ASSR 的技术参数以及成人和儿童 ASSR 阈值预测的准确性人口。在手稿的每个部分中，与 ASSR 相关的关键术语/概念在文本中以粗体显示，并在附录中的术语表中进行了简要定义。本教程包含大量图表，旨在引导读者了解与此响应相关的关键概念。此外，还包括几个汇总表，讨论各种主题，例如单频刺激技术与多频刺激技术对通过 ASSR 估计行为阈值的准确性的影响；单耳与双耳 ASSR 阈值的差异（如果有）； SNHL的程度和结构对ASSR阈值的影响； ASSR 的重测可靠性；神经成熟度对 ASSR 阈值的影响；以及影响骨传导 ASSR 的各种技术因素（即振荡器放置、耦合力和录音通道数量）的影响。结论：大多数研究人员都认为，未来 ASSR 测试将在临床听力学中发挥重要作用。因此，对于临床听力学家和 Au.D 来说非常重要。学生对与 ASSR 相关的技术概念有一个良好的基本了解，了解用于准确记录此反应的最佳刺激和记录参数，并了解使用 ASSR 来估计不同程度和配置的听力损失婴儿的行为阈值的当前作用和/或局限性。
Background: The auditory steady state response (ASSR) is an auditory evoked potential (AEP) that can be used to objectively estimate hearing sensitivity in individuals with normal hearing sensitivity and with various degrees and configurations of sensorineural hearing loss (SNHL). For this reason, many audiologists want to learn more about the stimulus and recording parameters used to successfully acquire this response, as well as information regarding how accurately this response predicts behavioral thresholds across various clinical populations.Purpose: The scientific goal is to create a tutorial on the ASSR for doctor of audiology (Au.D.) students and audiologists with limited (1-5 yr) clinical experience with AEPs. This tutorial is needed because the ASSR is unique when compared to other AEPs with regard to the type of terminology used to describe this response, the types of stimuli used to record this response, how these stimuli are delivered, the methods of objectively analyzing the response, and techniques used to calibrate the stimuli. A second goal is to provide audiologists with an understanding of the accuracy with which the ASSR is able to estimate pure tone thresholds in a variety of adult and pediatric clinical populations.Design: This tutorial has been organized into various sections including the history of the ASSR, unique terminology associated with this response, the types of stimuli used to elicit the response, two common stimulation methods, methods of objectively analyzing the response, technical parameters for recording the ASSR, and the accuracy of ASSR threshold prediction in the adult and pediatric populations. In each section of the manuscript, key terminology/concepts associated with the ASSR are bolded in the text and are also briefly defined in a glossary found in the appendix. The tutorial contains numerous figures that are designed to walk the reader through the key concepts associated with this response. In addition, several summary tables have been included that discuss various topics such as the effects of single versus multifrequency stimulation techniques on the accuracy of estimating behavioral thresholds via the ASSR; differences, if any, in monaural versus binaural ASSR thresholds; the influence of degree and configuration of SNHL on ASSR thresholds; test-retest reliability of the ASSR; the influence of neuro-maturation on ASSR thresholds; and the influence of various technical factors (i.e., oscillator placement, coupling force, and the number of recording channels) that affect bone conducted ASSRs.Conclusion: Most researchers agree that, in the future, ASSR testing will play an important role in clinical audiology. Therefore, it is important for clinical audiologists and Au.D. students to have a good basic understanding of the technical concepts associated with the ASSR, a knowledge of optimal stimulus and recording parameters used to accurately record this response, and an appreciation of the current role and/or limitations of using the ASSR to estimate behavioral thresholds in infants with various degrees and configurations of hearing loss.
