That will depend on the individual I think. Some can listen during the night and be fine, others can't as it keeps them awake or affects their sleep too adversely. Others can use one type of subliminal and sleep fine, masked or ultrasonic, and yet the other drives them nuts trying to sleep. Some have very sensitive hearing, especially our younger users, so ultrasonics aren't usable by them for long periods of time, or at all. I don't think it's so cut and dry that one is better than the other 100% of the time. That's also part of the reason Shannon makes two kinds of masked subliminals, AND an ultrasonic. To give you the flexibility to experiment and choose which suits your needs and wishes the best. They all have the exact same subliminal program in them.
Also, aside from the reasons I gave, I think 6 hours a day and 6 hours a night, and 12 hours a day, is six of one, have a dozen of the other. Hours listened, is hours listened. As long as the volume is set to the right level, and you've made sure your speakers or headphones can play the sub properly, then as long as you hit the minimum amount daily, you'll see results.
Also, here's some more info to backup what I've said in more detail. Read the whole section to get a better understanding. I'm sure that will help out. Link: http://subliminal-talk.com/thread-5238-p...l#pid70061
