1. An acoustic attenuation device comprising:
a fan assembly, the fan assembly including:
a first fan module configured to direct a first airflow in a first direction; and
a second fan module adjacent to the first fan module and configured to direct a second airflow in a second direction opposite the first direction;
a first air deflector mounted to an outlet of the first fan module;
a second air deflector mounted to an inlet of the first fan module;
a third air deflector mounted to an inlet of the second fan module; and
a fourth air deflector mounted to an outlet of the second fan module;
wherein the second and fourth air deflectors are adjacent to one another but face in opposite directions and are configured to direct air exiting the second fan module away from air entering the first fan module, and
wherein the first and third air deflectors are adjacent to one another but face in opposite directions and are configured to direct air exiting the first fan module away from air entering the second fan module; and
acoustic attenuating foam, wherein the acoustic attenuating foam has a two-dimensional (2-D) surface and is applied to a flat interior surface of at least one of the first, second, third and fourth air deflectors.
