Answer:
*Sensory adaptation* is the common adaptation in all three sense. Sensory adaptation is the process in which changes in the sensitivity of sensory receptors occur in relation to the stimulus. All senses are believed to experience sensory adaptation.
Explanation:
This adaptation is shared as well as used differently as explained below.
1) Hearing+balance :In terms of hearing, our ears adapt to loud sound as it hits the small bones located in the inner ear. The loud sound leads the inner ear bone/s to contract. This contraction causes the reduction or delay of transmission of sound vibrations to the inner ear. Detection of the vibrations follows. However, this process of auditory adaptation usually does not work very well with loud sounds that are sudden or instantaneous. Examples of these sounds are gun shots or explosions
2)Smell :Low concentrations of several chemicals present in the air can be detected by the sensory receptors in the nose. These chemicals that we quickly detect include those in perfumes or air fresheners
