1. An information handling system, comprising:
at least one processor;
a memory medium, coupled to the at least one processor, that stores an operating system and at least one application executable by the at least one processor;
a plurality of fans;
a chassis configured to house components of the information handling system, the chassis including:
a lid; and
a body including a bottom sidewall, a first sidewall, a second sidewall, a front sidewall, and a back sidewall,
wherein the chassis includes a plurality of holes through the chassis,
wherein the lid includes a first subset of holes of the plurality of holes, wherein the bottom sidewall includes a second subset of holes of the plurality of holes,
wherein the first sidewall includes a third subset of holes of the plurality of holes,
wherein the second sidewall includes a fourth subset of holes of the plurality of holes; and
a plurality of mats fastened to the chassis via at least one adhesive;
wherein the plurality of mats cover the plurality of holes and is in direct contact with the plurality of holes such that the plurality of mats cover are directly adjacent to the plurality of holes,
wherein a first mat of the plurality of mats is fastened to the lid of the chassis and covers the first set of holes of the plurality of holes,
wherein a second mat of the plurality of mats is a single mat and fastened to the first, second, and bottom sidewalls and covers the second, third, and fourth sets of holes of the plurality of holes,
wherein the plurality of mats and the plurality of holes are configured to reduce reflected acoustic energy within the chassis produced by the plurality of fans.
