Abstract
Plate for sound-absorbing coating, which consists essentially of a plurality of profiles articulated together, each formed by tubular bodies joined together by grooved areas, both tubular bodies and grooves being provided with external openings for the passage of sound waves to be absorbed, whose profiles are limited by their longitudinal edges, respectively, by a tube and an arrow-tipped fin, destined to be crimped in a longitudinal slit made in the tube corresponding to the adjacent profile, being attached to the face back of the profiles a sound-absorbing layer.
