a front face (2) and a rear face (3), and
recesses (4, 6) which extend from the front face (2) and from the rear face (3) into the acoustic panel (1),
wherein at least one front-face recess (4) and one rear-face recess (6) are arranged so as to be offset from one another in sections and comprise a through-opening (7)
wherein
locking profiles (16), which correspond to one another and which are lockable to one another without the use of adhesive, are arranged on at least two opposing side edges (10a, 10b) and
the front-face recesses (4) protrude to below a profile plane (P) of the acoustic panel, wherein the profile plane (P), starting from the front face (2), extends parallel to the front face and rear face (2, 3) at the deepest point of the locking profiles (16).
