Sound

The physical body has the potential for perceiving stimuli on a generalized basis. Although the eyes are for seeing and ears for hearing and so forth the potentials of physical body include the capacity to hear for example through any given portion of the bodily expanse.

Sound then can be felt as well as heard and you can say that the sound is felt in the depth of the tissues.

Colors may be perceived as sound (chromesthesia or colored heafing). They have connection with human moods.

Sound alone entering the body instantaneously changes it. Any perception instantly changes the perceiver. It also changes the things perceived.

Many people undergo some form of chromesthesia that is certain colors or color patterns are seen upon hearing certain sounds.
