Black Screen Droning Deep Fan 1 Hour White Noise

One hour of deep, rhythmic droning fan noise. Blocks out most other noise and allowing the mind to drift, or focus, without the imposed emotional influence of music. This is a large barrel almost-industrial fan used for white noise. Drowns out other sound, rhythm is nearly constant and contains no jarring transitions-- without having to buy a giant fan to get it. May be too bold for some nervous systems, while perfect for others who need stronger aural input, or something making sound in the background to make a room feel less oppressively quiet.
