It seems no coincidence that one's sense of balance and sense of hearing incorporate themselves in the same region of the human body - the inner ear. Just like in perceiving something heard, one senses balance through the movement, diffusion, and adjustment to gravity by the fluids within the inner ear, particularly the cochlea and semicircular canals, both of which eventually attach themselves to the same nerve, the vestibular cochlear nerve, subsequently leading to the brain.
Additionally, both hearing and the sense of balance sense through vibrations, placing the smallest and most sensitive bones of the body, the malleus, incus, and stapes. These vibrations lead to the same pathways, disrupting the fluids within the cochlea and three semicircular canals (one vertical, one horizontal, one diagnal).
Thus, by the same means of perception of balance and hearing, but interpreted differently in the temporal lobe and sensory cortex of the brain, this, I believe, makes the sense of balance and hearing nearly synonymous.
