Abstract
A method has been developed for tuning the microphone array for optimal visualization of acoustic dipoles. Acoustic dipoles were generated under experimental conditions in an anechoic chamber using a subsonic air flow around a thin metal rod and thin rectangular plate. To confirm the operability of this approach, we compared the visualization maps obtained using the approach with the results obtained with a similar array class tuned in the traditional monopole method. The developed approach, which adapts the array to the dipole radiation model and modifies the transfer functions that take into account the influence of the incidence pattern of sound waves, demonstrates an increase in the array’s dynamic range with optimal microphone placement.
