Scope: This part specifies an engineering method (level 2 accuracy), which uses the sound intensity method to measure the emission sound pressure level at the working position of machines and equipment and other designated positions on site. This method is GB/T 17248.2, GB/T 17248.3 and Another optional on-site measurement method other than GB/T 17248.5. When the background noise and sound field index meet the requirements, this method is applicable to all test environments. This section applies to equipment emitting steady-state broadband noise. These noises can vary from cycle to cycle, with or without discrete frequency components or narrowband components
