Apparatus and method for controlling the orientation of a fundamental panel vibration mode shape of a structure, such as a skin panel of a fuselage of an aircraft, relative to the direction of a turbulent boundary layer flow over the fuselage, and in a manner to achieve a level of noise reduction within the fuselage. The fuselage is constructed either through orientating stringers and/or frame members, or by using stiffening members placed diagonally between the stringers and frame members, in a manner that produces a fundamental panel vibration mode shape that extends at an angle of between about 30.degree.-45.degree. relative to the direction of the turbulent boundary layer flow over the fuselage. Aligning the fundamental panel vibration mode shape at an angle of between about 30.degree.-45.degree. relative to the direction of the turbulent boundary layer flow results in a reduction of the vibration response of the skin panel, and thus a reduction in the noise level within the fuselage.
