Microflow
Microflow can directly measure at one spot the sound pressure and acoustic particle velocity. Any sound field is described by two complementary acoustic properties, the scalar value 'sound pressure' and the vector value 'particle velocity'. In the acoustic near field, acoustic particle velocity is the dominant acoustic property. The Microflow is the only sensor which physically can measure the acoustic particle velocity directly. It can be used for a variety of applications but is mainly used in situations when size is important. The properties like sound intensity, sound power, acoustic absorption can be measured under a very high spatial resolution on small objects as for example laptop or cellphones. Or for example when the sound power output of cars dashboard needs to be determined, the part where the front window comes close to the dashboard and thus space is limited.
Beneficial of the measurement principle is that measurement can be done in-situ under realistic condition. The sensors have no need to create anechoic conditions and can be used within closed cavities, such as a car interior, the sensor is not having P/I ( pressure over intensity ) index problems.
