You feel vibrations; the deaf may "hear" vibrations.

Wonderful things are happening in the human brain. Yes, hearing vibrations as opposed to feeling them. The portions of the brain of a deaf person which are dedicated to hearing are not being used, right? WRONG, those regions  (auditory cortex) are "looking" for stimulation and those portion of the brain responsible for FEELING vibrations  are willing and able  share the stimuli of "vibrations" with the formerly unused neurons to let them interpret vibration as quasi-sounds.  Both regions require the same type of neural processing.

An article in the prestigious magazine Nature (Nov. 27, 2001) covers this exact subject. Erica Klarreich point out that Beethoven sawed the leg of his piano do that he could better feel ("Hear) the vibrations.
