“Air”
(4): virtual beamforming
Industrial
Engineering Dept.

Advanced Industrial Design in Acoustic
To increase the directivity of the scanning
equipment processing
software has been modified, allowing a “virtual” beamforming making use of a number of adjacent impulse
responses (optimal results Û virtual array of 7 mic.).
Measure without beamforming (left) and with
fixed focalization at 3.5 m (right).
