AB  - The engineered measuring probe uses three pairs of miniature microphones coupled. The signals from the microphones after an initial amplification are fed to differential circuits. Due to the required symmetry of the circuit it was necessary to select electronic components very carefully. Moreover, additional digital signal processing techniques were applied to avoid amplitude and phase mismatch. The view of the engineered probe is presented in photographs. Characteristics of the probe measured in an anechoic chamber are attached followed by a discussion of achieved results. The obtained results were compared with the reference USP probe, produced by the Microflown company.
