Acoustic absorbing structures
An acoustic absorbing structure comprises a surface comprising an array of apertures 103a, 103b, each aperture defining an opening for a corresponding channel 105, each channel forming a non-resonant acoustic attenuation structure with an axially decreasing cross-section over at least a portion of the length of the channel.
