要約

Interference immunity of directional microphones for spatially distributed signal and noise sources has been studied. A new parameter "off-axis noise suppression index" has been suggested and engineering formulas for its calculation have been obtained. Recommendations on the use of directional microphones, which ensure maximum off-axis noise suppression, have been given.
