The invention relates to an acoustic treatment device for a cooling system of a vehicle. The acoustic treatment device (1) is intended to be fitted to a cooling system of a vehicle and comprises at least one wall (4) which participates in delimiting a duct (2) for the circulation of an air flow, the acoustic treatment device (1) comprising at least one array of resonators (16) formed by one or more rows (18) of resonators (16) arranged around the duct (2) perpendicular to an axis of elongation (A) of the duct, each resonator (16) of a row (18) of resonators (16) comprising at least one cavity (20) arranged in the wall (4) and a neck (22) connecting the cavity (20) to the duct (2), characterized in that, at least for a given dimension of the cavity (20) or of the neck (22), at least one resonator (16) of the row (18) has a value that is different from the value of the corresponding dimension of the other resonators (16) of the row (18).
