As a jackhammer operator who has experienced prolonged exposure to high-amplitude drilling, Alex is beginning to lose his hearing. It is most likely that this hearing loss results from damage to

Explanation:

Hair cells are present in the ears of all the vertebrates. They detect the movement in the environment through mechanotransduction. they are the sensory receptors of the vestibular and auditory system in vertebrae.  

Disease, ageing and ototoxic drugs can damage the hair cells, once damaged they cannot be regenerated in humans while they do regenerate in other species to restore hearing.  Listening to loud noise or sound form long time overworks the  hair cells and the cells can die as a result of it.

The jackhammer's hair cells could have been damaged due to prolonged exposure to the high-amplitude hearing.
