Summary:

Monopole sound sources (id est omni directional sound sources with a known volume velocity) are essential for reciprocal measurements used in vehicle interior panel noise contribution analysis. Until recently, these monopole sound sources use a sound pressure transducer sensor as a reference sensor. A novel monopole sound source principle is demonstrated that uses a Microflown (acoustic particle velocity) sensor as a reference sensor.As compared to a sound source that uses a sound pressure transducer as a reference sensor, the new sound sources demonstrated are relatively easy to calibrate, not sensitive to changes in ambient temperatures, and suitable to use in all sorts of acoustic environments
