An aircraft door arrangement includes a door, a door seal, and a door opening. The door opening has an opening edge adjoining the door opening and extending into the aircraft fuselage, at which a seal seat is arranged, which can be brought into flush contact with the door seal. A hollow space, partially covered by the edge region of the door, is formed by the door seal, the seal seat, and the opening edge. A gap (located between the door and the door opening when the aircraft door is closed) is connected with the hollow space. A sound reducing profile is arranged at the opening edge in the hollow space, and it includes a sound reflecting surface oriented oblique with respect to a surface of the door, which is adjacent to the gap. The sound reflecting surface at least partially follows the course of the gap.
