ACOUSTIC DAMPENING AIR MOVING DEVICE HOUSING

An air moving device (AMD) includes a housing that dampens noise and routes airflow. The AMD housing includes a focal-bearing surface that has an associated focal point. The focal-bearing surface routes airflow through the AMD housing and reflects and concentrates noise to the focal point. The AMD h...

Beschreibung
Zusammenfassung:	An air moving device (AMD) includes a housing that dampens noise and routes airflow. The AMD housing includes a focal-bearing surface that has an associated focal point. The focal-bearing surface routes airflow through the AMD housing and reflects and concentrates noise to the focal point. The AMD housing further includes a noise dampening structure at the focal point to reduce, absorb, and/or dampen the concentrated noise. Because the noise is concentrated, a relatively smaller size noise dampening structure may effectively or adequately reduce or dampen AMD noise. The smaller size noise dampening structure relatively reduces airflow impedance. As such, AMD housing may provide for both reduced AMD noise and relatively reduced airflow impedance therein and/or therefrom.
