This is a combination of factors:
- In addition to receiving the physical dimension, your body perceives the frequencies as hearing because part of the vibrations travel through your body and to your inner ears. This is a benefit of the SUBPAC because it’s an extension of hearing, not just something on you feel.
- You are closer to it than other people. So you can hear it a bit but it still is silent to other people in the room and to your neighbors.
