The acoustic imagery is our speciality. Our line of products, our publications and our many applicability such as industry, R & D and environment reflect our means of actions.ACB started by obtaining an algorithm of beamforming in the temporal field to analyze any unstable acoustic phenomenon like thermal engines, mobile aéro-accoustics and other objects. We supplement this mode of processing by a holographic technique, also working in the temporal field. The association under the same interface of the 2 algorithms has the principal advantage a remarkable extension of the frequency band of analysis.
ACB proposes 3 sizes of antennas compatibles Beamforming - Holography to meet the industrial situations. The examples are given for 64 microphones :
- 30 cm X 30 cm Objects of small sizes 300Hz - 10.000 Hz
- 70cm X 70 cm Objects of average sizes 150Hz - 4000 Hz
- 140cm X 140 cm Objects of big sizes 80 Hz - 2000 Hz
Finally, a particular processing of waves reflected on the ground and the direct ones enables us to virtually double the size and the number of microphones for the final result. This Miroir algorithm is available only starting from a technical base of beamforming.
