标准摘要
[中文适用范围]: 本部分规定了一种工程方法(2级准确度),该方法利用声强法现场测定机器和设备工作位置和其 他指定位置发射声压级,该方法是GB/T17248.2、GB/T17248.3和GB/T17248.5之外的另一种可供 选用的现场测量方法。当背景噪声和声场指数满足要求时,该方法适用于所有的测试环境。 本部分适用于发射稳态宽带噪声的没备。这些噪声在不同的运行周期内可以有所不同,噪声可以 有或没有离散频率成分或者窄带成分。 [外文原描述]: ISO 11205:2003 specifies an engineering method (grade 2 accuracy) to determine the emission sound pressure level of machines in situ , at the work station or at other specified positions, using sound intensity. It is an alternative to ISO 11201, ISO 11202 and ISO 11204 for in situ measurements. It is applicable to all kinds of test environments provided that the requirements on background noise and field indicators are fulfilled. ISO 11205:2003 is applicable to equipment emitting stationary broadband noise. The noise can differ between operational cycles and can be with or without discrete frequency or narrow band components.
