声音强度校准器
声强校准器设计用于现场声压校准和压力-剩余强度-指数验证
Type 4297
声强校准器Type 4297用于现场声压校准和压力-剩余强度-指数验证。
该设备是一个完整的声强校准器,在一个紧凑的便携式单元中,内置声源。声反馈系统根据大气压力的变化自动调节,符合IEC 61043标准。
声强校准器 Type 4297 使测量声强的仪器能够进行精确校准。它打算与Brüel & Kjær声强探头3599和3654配合使用,带有声强麦克风对TYPE 4197。麦克风必须与¼"前置放大器一起使用。
声强校准器可用于声压灵敏度的校准。为此,麦克风都位于校准室中。无需拆卸探头,两个麦克风的声压(振幅和相位)完全相同。不需要气压计,因为精确的反馈系统将声压级保持在恒定值。
宽带声源用于测量压力-残余强度指数谱。用于评估声强测量的准确性。

The most important and unique feature of Type 4297 is that there is no need to dismantle the sound-intensity probe for calibration.
The calibrator is optimised for use with Hand-held Sound Intensity Analyzer Type 2270 G, but it can also be used with sound intensity analysis systems.
A calibration chart is supplied that states the levels that should be detected during calibration.
