If they are in the same room, you can affect them by playing your subliminal on a speaker, or sometimes even if you play it loudly enough on headphones. If they are in another room, they may also be affected if the subliminal audio is loud enough through the wall(s) for their subconscious to detect. Subliminal audio remains effective down to the range of -60 to -80 decibels at the ear, which is extremely faint. We have heard cases of office mates, room mates, people in nearby apartments and others being affected noticeably by the use of a subliminal, even in a closed room.
