The new mid-high frequency volume velocity source is completely redesigned to deliver a final product that on any aspect drives it to a higher level. The improved performance going hand in hand with a user friendly experience, puts it top of your mind when looking for a sound source.

The sound source has an embedded reference particle velocity sensor. This reference sensor measures the output of the source, volume velocity, directly and accurately.

This Mid-High Frequency Volume Velocity Source can be used for a wide range of applications like transfer path analysis, airborne source quantification, component vibroacoustic behavior characterization, airborne source quantification and pass by noise simulations. This omnidirectional source will guide your decisions in the right direction.
