电声学 听觉测量设备 第7部分：听觉诱发电位测量仪器

[中文适用范围]： IEC 60645-7:2025适用于专为测量由短时声学或振动刺激引起的耳内、听神经和脑干诱发听觉电位的仪器。本文件规定了制造商应指定的特性，规定了两类仪器（筛查型和诊断/临床型）的性能要求，并规定了这些类型仪器应具备的功能。此外，本文件还规定了描述用于听觉诱发电位设备及其他设备（如耳声发射仪器）的短时听觉参考和测试信号的物理特性（以电信号波形表示）的方法，以及测量这些信号的方法。本文件的目的是确保在符合本文件的不同仪器上，于可比测试条件下进行的测量结果具有一致性。本文件不旨在限制新功能的开发或集成，也不应阻止创新方法的采用。对受试者施加电刺激进行诱发反应测量的内容超出了本文件的范围。 [外文原描述]： IEC 60645-7:2025 applies to instruments designed for the measurement of auditory evoked potentials from the inner ear, the auditory nerve, and the brainstem, evoked by either acoustic or vibratory stimuli of short duration. This document defines the characteristics to be specified by the manufacturer, specifies performance requirements for two types of instruments (screening and diagnostic/clinical), and specifies the functions to be provided on these types. It also specifies a means of describing the physical characteristics, in terms of electrical waveforms, of audiometric reference and test signals of short duration used with auditory evoked potential equipment and other equipment (e.g. otoacoustic emission instruments), and methods for their measurement. The purpose of this document is to ensure that measurements made under comparable test conditions with different instruments complying with this document will be consistent. This document is not intended to restrict development or incorporation of new features, nor to discourage innovative approaches. Evoked response measurement using the application of electric stimuli to a subject is beyond the scope of this document.
