Abstract:
An aircraft includes a fuselage, a cabin surface, and a first chamber. The cabin surface is disposed within the fuselage and defines a first aperture and at least part of a cabin air mass having a first acoustic mode. The first chamber is acoustically coupled with the aperture and has a length that is one quarter of a wavelength of sound at the first acoustic mode.
