IMAGING METHOD AND DEVICE INTENDED FOR SPEECH SOUND PROPAGATION DETECTION Russian patent published in 2009 - IPC G09B21/00 G10L21/06 

FIELD: physics, acoustics.

SUBSTANCE: invention refers to speech sound propagation detectors and deaf-mute spatial orientation facilities. Sound propagation is displayed relative to direction of listener's direct sight on colour displays by means of vertical indicating strips of width varying depending on sound propagation change. Indicating strips travel across displays field relative to neutral position depending on sound propagation from above or from below with respect to patient's head. Colour of vertical indicating strips varies depending on speech distribution propagation change in two potential opposite directions: in front or behind. The device contains eyeglass frame with left and right eyepieces, two ear arms with mounted microphones, left and right speech perception and imaging channels, speech sound identification unit, left and right colour liquid crystal displays. The central microphone is mounted by means of ball-and-socket joint on eyeglass frame bridge.

EFFECT: development of speech sound propagation detector and deaf-mute spatial orientation facility.
