Sound Intensity / Sound Power

ACI conducts sound intensity and sound power level measurements using a portable dual microphone intensity probe with a digital camera and motion tracking capability.

The result is a color contour map of the noise producing equipment at various frequencies.  This can be used for specific noise source identification  

Sound Power Levels can be measured as per ISO 9614-2

Standards and Guidelines:

• ISO 9614-2:  Determination of sound power levels of noise sources using intensity
• ISO 3744: Determination of sound power levels and sound energy levels of noise sources using sound pressure.
• IEEE C57.12.90-2010:  Standard test code for Liquid-Immersed distribution, power, and regulating transformers.
