DESCRIPTION:A new concept of a directional sound sensor circuitry with a du
 al-microphone and a parabolic rellecting bowl was costructed and presented
 . Its purpose is to eliminate inappropriate sounds coming from directions 
 perpendicular to the main axis direction of the arrangement. The noise eli
 mination was realized using adaptive filtering. With the proposed equipmen
 t more than 12 dB improvement of the signal-to-noise ratio has been achiev
 ed. usefulness of the built equipment has been confirmed with successful s
 peech intelligibility tests performed with both logatoms and sentences.\n\
