METHOD FOR HIGHLY DIRECTIONAL RECEPTION OF SOUND WAVES Russian patent published in 2013 - IPC H04R31/00

Abstract RU 2494570 C1

FIELD: physics.

SUBSTANCE: method in which during lateral arrival of sound waves at an angle of ±α to the zero position of the axis of a disclosed microphone receiver, directed towards the sound source, a time delay is formed between two acoustic inputs, equal to: ${Δt}_{d} = \frac{L \cdot sinα}{C_{s}},$ where C_s is the speed of sound, L is the distance between acoustic inputs.

EFFECT: smaller linear dimensions of the receiver while improving high directivity of receiving sound.
