汽车充气装置的脉冲噪声

[中文适用范围]： 本文档提供了评估充气装置（例如安全气囊和安全带预紧器）产生的脉冲噪声引起听力损失风险的新方法。文档介绍了脉冲噪声测量技术和评估标准的背景信息。关于测试细节的相关信息，例如前置放大器规格、滤波方法和标准，将在未来的推荐实践中讨论。 本文档旨在传播有关这些工具和技术的信息，以协助汽车约束系统的开发过程。 [外文原描述]： New methods are available to assist in evaluating the risk of impulse noise-induced hearing loss from inflatable devices, for example, airbags and seat belt pretensioners. This document presents some background on impulse noise measurement techniques and assessment criteria. Related information relative to test details, for example, preamplifier specifications and filtering methods and criteria, will be discussed in a future recommended practice.Cross Reference: ANSIS12.7,J247,J247_201211
