Abstract
Embodiments of the present invention are generally related to acoustic white noise machines. In particular, embodiments of the present invention are directed to an acoustic white noise machine that comprises a fan blade designed to shear airflow against a sharp edge in order to create broadband turbulent noise. Embodiments of the present invention may further include an adjustable enclosure that may be manipulated via the rotation or other movement of an outer shell to alter the amount of air being sheared by the fan blade, thereby changing the frequencies which resonate in the adjustable enclosure.
