GRAS Sound and Vibration
G.R.A.S. Sound & Vibration has concentrated its development
effort and production expertise on Acoustic front-end products.
This includes in principle all products necessary for the precise

Microflown Technologies
Microflown Technologies will be exhibiting it’s particle velocity
based sound probes and acoustic camera arrays.
As various scientific papers recently submitted submitted
reveal, particle velocity based measurement techniques
overcome much of the problems encountered in p-p sound
intensity measurements, sound source localisation and sound
field prediction techniques.»
