A structural panel (20) may be configured for attenuating noise. This panel (20) includes a first skin (22), a second skin (24) and a core (26) forming a plurality of cavities (42) vertically between the first skin (22) and the second skin (24). The core (26) may include a wall (36) connected to and extending vertically between the first skin (22) and the second skin (24). The wall (36) may be laterally between and fluidly separate at least a first of the cavities (42) from a second of the cavities (42). The wall (36) may include a vertical stiffener (50). One or more perforations (30) in the first skin (22) may be fluidly coupled with the first of the cavities (42).
