Your best subliminal`s training routine

[ArcticFox]

I cant tell if its the optimum setup but here is what ive finally got down to:

My speakers are setup in my bedroom and are M-Audio Carbon BX5s connected to my Iphone 4 which is used just for subs. I turn on the US as soon as I get home. This way I get at least 8 hours everyday from sleeping, and hopefully a couple more hours while I potter around the room. I then try to get 1 hour of masked while I walk to work.

I've measured the Db level of the US and it is a consistent 70dB with the meter reading taken from my pillow.

I might setup a US in the front room to play while I watch TV. From reading others posts I could be getting 12-16 hours which potentially could double my daily sub usage - which I think will have a dramatic effect.

I'm also interested to know if its safe (for others) to play an US at my desk, its an open plan office and people are frequently talking to me, and around my desk. (there is a printer sat right behind me).
