A sound-damping panel. The sound-damping panel includes a first face sheet. The sound-damping panel also includes a core connected to the first face sheet. The core has a honeycomb structure. Walls of the honeycomb structure are embedded with a viscoelastic material configured to dampen sound in a pre-selected frequency range. The sound-damping panel also includes a second face sheet connected to the core, the second face sheet opposite the first face sheet relative to the core.
