Microflown
Microflown Technologies are based in the Netherlands and developed the unique Microflown probe which directly measures 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 Microflown is the world’s first and only MEMS technology based sensor that can measure acoustic particle velocity. By measuring the temperature difference across two extremely thin platinum wires placed in parallel, this extremely fast mass flow sensor is capable of monitoring the movement of air particles.
U Regular Probe
The ½ inch U Regular integrates one single Microflown sensor. The Microflown is the only transducer which can physically measure the acoustic particle velocity directly.…

A Deep Dive into Scan&Paint 2D
April 15, 2026
NVH Engineers face acoustic challenges every day. This could be troubleshooting noise, optimising products or improving soundproofing. Identifying the true source of unwanted sound is rarely straightforward. Traditional acoustic measurements can tell you how loud something is, but they often struggle to clearly show where the noise is coming from.…
