A ventilation device for a passenger compartment (H), specifically for an automobile, includes a casing (1) with an exterior air intake (4) and a recirculated air intake (5) that supply a fan (9-13) with a variable suction airflow rate that is housed inside the casing, controlled by at least one variable-position air intake shutter (8). At least one of the exterior air intakes (4) and recirculated air intakes (5) includes attenuation means (15) capable of limiting propagation toward the outside of the casing (1), at least on the passenger compartment (H) side, of the sound waves generated by the airflow circulating in the air intakes (4, 5).
