FIELD: physics, acoustics.
SUBSTANCE: invention relates to noise cancelling means designed to be installed on aircraft. An acoustic panel for an aircraft gondola having at least one structure capable of capturing noise, one solid envelope without acoustic openings and one acoustic envelope in contact with said structure. Said acoustic envelope has a row of stacked layers of composite flat strips, each aligned by its longitudinal axis which defines a certain direction, wherein the longitudinal axes of strips of the same layer are parallel to each other, and said strips of said same layer are spaced from each other such that acoustic openings are formed in the acoustic envelope.
EFFECT: high reliability of the structure.
