What things might affect someone hearing a silent subliminal being played in the next room over?
I know if I play music at normal level with the door open it can be heard in several rooms but not sure if a silent subliminal would make it out the door or have effect on someone in the next room.
If I take a source speech volume where the original file can be heard in the next room then take that volume file and make it a silent subliminal without decreasing the volume…. will that silent subliminal that results also be able to be “heard” in the next room?
Does any of the nyquyst prompt affects or the frequency adjustments etc change the likelihood of that sound carrying through a wall or door or furniture? Will it carry the same distance as the original out loud file that was used to make the silent subliminal?
There are many factors that influence what gets heard where. The total volume of the sound is one of them, but the pitch and speaker placement can have an even greater influence.
Higher frequencies tend to be more directional, for example. But they also tend to be both better absorbed by some materials, yet better reflected by others. Consider the effectiveness of Bose’s “direct/reflecting” speakers. Or think of the “magic” spot pairs in certain rooms, where a whispered conversation at one of them can be heard a clear as day in the other, but not at all two or three feet away.
Thus you could be surprised that an ultrasonic that might otherwise be absorbed by bedding, actually gets reflected out because the speaker’s tweeter is pointed at the wall behind or beside the bed.
