Abstract
A noise producing fan with low air movement or variable air movement is provided. The device comprises a conventional mechanical fan that is adapted to provide a soothing and steady volume of ambient noise for a user to block out background noise and sleep comfortably. The mechanical fan includes several embodiments, including different fan blade arrangements, means of interchanging fan blades on the mechanical fan hub, different fan shrouds that allow for access to the fan hub, and finally an imbalanced fan hub that creates an oscillatory motion to increase noise production. The fan blades for low air movement and efficient noise generation are flat or perforated, and secure to the fan hub as it oscillates and rotates within the mechanical fan housing.

1) A noise generating fan assembly, comprising:
- a fan housing having a front portion, a rear portion, and an interior, said fan housing supported by a stand;
- an electric motor connected to a fan blade assembly within said fan housing interior;
- said fan blade assembly comprising a fan hub and a plurality of fan blades extending therefrom;
- said fan blades comprising a planar forward surface and a planar rear surface;
- said fan blades adapted to create noise during rotation of said electric motor with minimal air flow through said fan housing front portion.
6) A noise generating fan assembly, comprising:
- a fan housing having a front portion, a rear portion, and an interior, said fan housing supported by a stand;
- an electric motor connected to a fan blade assembly within said fan housing interior;
- said fan blade assembly comprising a fan hub and a plurality of fan blades extending therefrom;
- said fan blades comprising elongated members having a narrow planform area;
- said fan blades adapted to create noise during rotation of said electric motor with minimal air flow through said fan housing front portion.
