Acoustic dampening air moving device housing

An air moving device comprising:

• a housing comprising an airflow inlet, an airflow outlet, a downstream focal-bearing surface, and an upstream focal-bearing surface;
• a fan system comprising a fan that rotates about an axis of rotation that emits noise as it impinges an airflow in a first direction away from the airflow outlet and against the downstream focal-bearing surface, wherein the downstream focal-bearing surface redirects the airflow in a second direction at an acute angle to the first direction toward the airflow outlet;
• a first noise dampening structure at a focal point of the downstream focal-bearing surface, wherein the downstream focal-bearing surface redirects and concentrates the noise at the focal point of the downstream focal-bearing surface, and wherein the first noise dampening structure reduces the concentrated noise;
• and
• a second noise dampening structure at a focal point of the upstream focal-bearing surface, wherein the upstream focal-bearing surface redirects and concentrates the noise at the focal point of the upstream focal-bearing surface, and wherein the second noise dampening structure reduces the concentrated noise
• wherein the first noise dampening structure and the second noise dampening structure are aligned with the axis of rotation.
