Abstract
A sound attenuation panel that includes an incident wall and a frame unit connected to the incident wall. The incident wall defines an aperture therethrough. The frame unit includes multiple spoke members spaced apart from one another and radially extending from one or more central hub openings of the frame unit. The one or more central hub openings align with the aperture of the incident wall. The frame unit defines channels between adjacent pairs of the spoke members. The channels fluidly connect to the one or more central hub openings. The frame unit is configured to receive sound waves into the central hub opening through the aperture of the incident wall to dissipate the sound waves through the channels between the spoke members.
