Abstract
A sound absorbing structure includes a vehicle structure having a surface and at least one acoustic scatterer coupled to the surface. The at least one acoustic scatterer has a resonant frequency. The at least one acoustic scatterer has an opening and at least one channel. The at least one channel has a channel open end and a channel terminal end, the channel open end being in fluid communication with the opening. The sound absorbing structure may be configured to absorb sound waves at a certain frequency generated by a noise source. The certain frequency may be substantially similar to the resonant frequency of the at least one acoustic scatterer.
