Ultrasonic track range - Subeternal - 10-30-2012
I was curious to know the area of proximity that ultrasonics could reach when played on independent speakers as opposed to a cellphone. Considering you have to listen to ultrasonic at a lower volume I figure its ability to fill a room is much greater.
The reason I ask is because I normally listen in my living room during the day but sometimes I'm in the kitchen for extended periods which is next to the living room. Also there was another situation in the past where I used to sleep in the open loft right above the living room and I decided to leave my main stereo down stairs thinking I would get exposure from down there while I sleep.

I have found that playing a subliminal on my cell phone at maximum volume, I can hear and be affected by it in any room in my entire house, as long as doors between myself and the phone are open.
You can hear it anywhere in a 20x20 room and be affected by it on a cell phone at 33% volume and sometimes less.
How to know where it can be heard? Play the trickling stream track at the intended volume. Wherever you can hear the trickling stream, you can hear the ultrasonic. I would say it's probable that you can be affected by the masked subliminal tracks at about 50 to 75% of that distance.
