ACOUSTIC STRUCTURE WITH WIDER SUPPRESSING RANGE Russian patent published in 2016 - IPC G10K11/172

Abstract RU 2596960 C2

FIELD: sound.

SUBSTANCE: frequency band or acoustic range of nacelle or acoustic structure of another type is increased due to acoustic connection of cellular cells to each other to form pairs of acoustic cells, having effective acoustic or resonator length up twice greater than acoustic length of separate cells.

EFFECT: formation of pairs of acoustic cells.
