该方法通过测定冲击声的显著性对声源进行客观分类，目的是与社区反应相关。这种测量冲击声显著性的方法适用于未识别为枪声或高能冲击声的声源。它通常会在0,0？范围内进行调整dB到9.0dB。这些调整旨在将声源归类为常规冲击声源或高冲击声源，并适用ISO？中规定的惩罚1996-1. 然而，这些调整可以直接应用，正如在NT中所做的那样ACOU112和BS4142。ISO1996-2提供了执行这些测量的额外指南。该方法旨在用于具有冲击特性的源，这些冲击特性尚未在ISO？中分类1996-1. 非详尽的示例列表包括压缩空气释放、废料处理、货物交付、带有卡嗒卡嗒的叉车、滑板坡道、工业剪切、气体排放、拆除中的冲击工具、电动铆接等。该方法不适用于火器发出的声音。尽管显著性测量可能会得出相关结果，但研究表明，对这些来源的反应受到本文件范围以外的因素的影响。此外，该方法不适用于ISO？中规定的高能冲击声源1996-1.注意本方法不适用于职业性听力损失，不在本文件范围内。见附件A用于推荐的额外研究。

This method objectively categorises sources by determination of the prominence of impulsive sound, with the aim of correlating to community response. This method for measuring the prominence of impulsive sounds is intended for sources not identified as gunfire or high-energy impulsive sound. It typically produces adjustments in the range 0,0 dB to 9,0 dB. These adjustments are intended to be used to categorise the sources as either regular impulsive or highly impulsive sound sources and apply the penalty indicated in ISO 1996-1. However, the adjustments may be applied directly, as is done in NT ACOU 112^[2], and BS 4142^[3]. ISO 1996-2 provides additional guidance for performing these measurements.The method is intended for use on sources with impulsive characteristics that are not already categorised in ISO 1996-1. A non-exhaustive list of examples includes compressed air release, scrap handling, goods delivery, fork lifts with rattling forks, skateboard ramps, industrial shearing, gas discharges, percussive tools in demolition, powered riveting, etc.The method is not intended for use on sounds from firearms. Although the measurements of prominence may give relevant results, research has shown the response to these sources is influenced by factors outside of the scope of this document. In addition, the method is not intended to use for high-energy impulsive sound sources as specified in ISO 1996-1.NOTE      This method is not intended for occupational hearing loss, which is outside the scope of this document.See Annex A for recommended additional research.
