Abstract: A sound isolating ventilation panel is provided. The panel includes: a core assembly having a plurality of horizontal channels; a pair of cartridges having hollow centers and flanking both sides of the core assembly; and a pair of hollow sides flanking the pair of cartridges. Each of the cartridges has a proximally facing side having a plurality of air channel side apertures and a distally facing side comprising a plurality of sound resonator side apertures. A vertically oriented ventilation groove is formed through a front face of a first one of the cartridges and a vertically oriented ventilation groove is formed through a back face of the second one of the cartridges. The ventilation grooves, the hollow centers, the air channel side apertures and the horizontal channels together partially define Z-shaped air channels. The sound resonator side apertures and the hollow sides partially define a plurality of resonators.
