A sound-absorbing modular panel (10) is described, comprising a tubular jacket (11), formed BY a single body in plastic material, that defines a compartment (12) for accommodating sound-absorbing material (13). Inside the tubular jacket (11) there are defined longitudinal (19, 20, 21, 22, 23, 24), angular (19, 20, 21, 22) and/or central (23, 24) reinforcement portions, which develop in the direction (X) transverse to the thickness of the panel (10) and comprise a plurality of longitudinal ribs (31, 32, 33, 34) defining a plurality of longitudinal cells (35, 36, 37, 38). |
